CHAPTER 1 – INTRODUCTION

1.1 PREAMBLE

The tourism industry in Kerala has evolved, over the years, in to a significant one, thanks to the varied natural attractions and the effort made by the State and the private sector in marketing these attractions and providing the necessary infrastructure required by the sector. Innovative and novel measures are being taken even now by the industry in promoting tourism. Such measures add great value to Kerala tourism.

It is imperative that in order to add impetus to the growth of tourism industry in Kerala, there must be effective and efficient feeder airlines to link the airports of Kerala with its far-flung tourist destinations like Kumarakom, Thekkady, Munnar, etc. The generally accepted norm is that tourist resorts should be no more than one hour from the nearest airports. Thedestinations of Kerala are several hours away from the nearest airports and the roads are not in the best of conditions most of the time. Air link will be of use to the tourists as well as the travellers to these places.

Beaches and backwaters are two of the major tourist attractions of the State. Seaplanes can help in harnessing these resources by adding greater value to these resources. Maldives has proved it. Seaplanes based in Kerala can also be used in future to connect water bodies in the neighbouring States and Lakshadweep islands.

Seaplanes can help in linking the tourist destinations without expensive runways. As several of the tourist destinations are located close to water bodies, these can be used as the landing ground for seaplanes. Seaplane operations can also be turned in to a tourist attraction by offering an opportunity to take an aerial view of the magnificent panoramic view of God’s Own Country.

1.2 PROJECT BACKGROUND

The State of Kerala – God’s own Country, famous for its backwaters and beaches is amongst the highest visiting state among the tourists. In view to provide better connectivity to domestic and International tourist visiting Kerala and taking a new initiative, Govt. of Kerala with an object of boosting tourism, has decided to introduce Seaplane services in the state of Kerala.

To take this project forward, Govt. of Kerala has appointed Pawan Hans Helicopters Ltd. – a Govt. of India Enterprise, their consultant to conduct the feasibility Study to introduce Seaplane services. Introducing Seaplane services in the state shall not only increase the tourism activities in Kerala, but it shall place Kerala as the first state giving an opportunity to enjoy seaplane rides in the Mainland India.

1.3 KERALA

The state has an area of 38,863 (15,005 sq mi) and a population of 3.33 crore (33.3 million). It is bordered by Karnataka to the north and north-east, Tamil Nadu to the east and south, and the Arabian Sea to the west. Trivandrum is the state capital; other major cities are Kochi (Cochin) and Kozhikode(Calicut). Kerala is socially a very progressive society. It has the highest Human Development Index (HDI) among all Indian states: at 0.790 it is comparable to countries classified as having  Very High Human Development according to the United Nations Development Programme Human Development Report 2011. It has the highest literacy rate (93.91%), highest life expectancy(74 years) and lowest sex ratio(the ratio of the number of men to the number of women: 923 men per 1000 women) among Indian states.

1.3.1 IMPORTANCE

Kerala is an important international and internal tourist destination. In Kerala its backwaters, beaches, Ayurvedic tourism and tropical greenery are among its major attractions. National Geographic's Traveller magazine named Kerala as one of the "ten paradises of the world" and "50 must-see destinations of a lifetime" Travel + Leisure listed it as "one of the 100 great trips for the 21st century".

1.3.2   GEOGRAPHY

Kerala is wedged between the Lakshadweep Sea and the Western Ghats. Lying between north latitudes 8°18' and 12°48' and east longitudes 74°52' and 77°22' Kerala experiences the humid equatorial tropic climate. The state has a coast of length 590 km (370 mi) and the width of the state varies between 11 and 121 km (22–75 miles). Geographically, Kerala can be divided into three climatically distinct regions: the eastern highlands (rugged and cool mountainous terrain), the central midlands (rolling hills), and the western lowlands (coastal plains).

1.3.3   CLIMATE

With around 120–140 rainy days per year, Kerala has a wet and maritime tropical climate influenced by the seasonal heavy rains of the southwest summer monsoon and northeast winter monsoon. About 65 percent of the rainfall occurs during the first season (June to August), corresponding to the southwest monsoon, and the rest during the second season (September to December), corresponding to northeast monsoon. The mean daily temperatures range from 19.8 °C to 36.7 °C. Mean annual temperatures range from 25.0–27.5 °C in the coastal lowlands to 20.0–22.5 °C in the eastern highlands

1.3.4   DEMOGRAPHICS

Kerala is home to 3.44% of India's population; at 819 persons per km2, its land is nearly three times as densely settled as the rest of India, which is at a population density of 325 persons per km2. Kerala's rate of population growth is India's lowest, and Kerala's decadal growth (9.42% in 2001) is less than half the all-India average of 21.34%. Whereas Kerala's population more than doubled between 1951 and 1991 by adding 15.6 million people to reach 29.1 million residents in 1991, the population stood at less than 32 million by 2001. Kerala's coastal regions are the most densely settled, leaving the eastern hills and mountains comparatively sparsely populated.

1.3.4   TOURISM IN KERALA

Kerala is one of the popular tourist destinations in India. Its culture and traditions, coupled with its varied demographics, have made Kerala one of the most popular tourist destinations in the world. National Geographic's Travelers magazine names Kerala as one of the "ten paradises of the world" and "50 must see destinations of a lifetime". Travel and Leisure names Kerala as "One of the 100 great trips for the 21st century". Kerala's beaches, backwaters, mountain ranges and wildlife sanctuaries are the major attractions for both domestic and international tourists. The city of Kochi ranks first in the total number of international and domestic tourists in Kerala.

Until the early 1980s, Kerala was a relatively unknown destination, but in 1986 the government of Kerala declared tourism as an industry and it was the first state in India to do so. Aggressive marketing campaigns launched by the Kerala Tourism Development Corporation, the government agency that oversees tourism prospects of the state, laid the foundation for the growth of the tourism industry.In the decades that followed, Kerala's tourism industry was able to transform the state into one of the niche holiday destinations in India. Many innovative marketing strategies were used and the advertisements branded Kerala with a catchy tagline Kerala, God's Own Country.Today, Kerala Tourism is a global brand and regarded as one of the destinations with highest recall.

Kerala has pioneered in health and medical tourism in India and has attained international attention in this segment. Kerala is known for its ecotourism initiatives and in this segment it promotes mountaineering, trekking and bird-watching programmes in the Western Ghats as the major products.

The state's tourism industry is a major contributor to the state's economy, which is currently growing at a rate of 13.31%. The tourism industry provides employment opportunity to 1.2 million people.

The most popular tourist attractions in the state are beaches, backwaters and hill stations.Major beaches are at Kovalam, Varkala, Kappad, Muzhappilangad and Bekal. Popular hill stations are at Munnar, Wayanad, Wagamon, Peermade, Nelliamoathi and Ponmudi.

Kerala's ecotourism destinations include 12 wildlife sanctuaries and two national parks: Periyar Tiger Reserve, Neyyar Wildlife Sanctuary, Chinnar WildlifeSanctuary, Thattekad Bird Sanctuary, Wayanad Wildlife Sanctuary, Muthanga Wildlife Sanctuary and Eravikulam National Park are the most popular among them. The "backwaters" are an extensive network of interlocking rivers (41 west-flowing rivers), lakes, and canals that center around Alleppey, Kumarakom, Kollam and Punnamada (where the annual Nehru Trophy Boat Race is held in August). Cities such as Thiruvananthapuram, Kochi and Kozhikode are popular centres for their shopping and traditional theatrical performances.

Kerala is also a center of heritage and religious tourism sites. Padmanabhapuram Palace and the Mattancherry Palace are two notable heritage sites. The state is also famous for the large number of festivals (about 10,000 per year) it celebrates; of these, Onam and Thrissur Pooram attract a large inflow of foreign tourists. The main pilgrim tourist spots of Kerala are Sabarimala Temple, Aranmula Temple, Padmanabhaswamy Temple, Guruvayoor Temple, Chettikulangara Temple, Vadakumnathan Temple, Sarkara Devi Temple, Padanilam Parabrahma Temple, Beemapally mosque, Saint Thomas Syro-Malabar Catholic Church, Malayattoor, Parumala Church (Pathanamthitta) and St. Francis Church, Kochi.

2.5 WORLDWIDE SCHEDULE STRUCTURE OF SEAPLANES




2.6 ADVANTAGES OF SEAPLANE

Seaplanes can cater to a variety of air transportation requirements. The use of seaplanes in tourist destinations that are close to large water bodies like sea, lake, etc. is an obvious application. Maldives, for example, has a fairly large seaplane operation catering to the tourism industry there. Seaplanes can also be used to access remote areas that may not have runways for normal planes to land but may have suitable water bodies on which seaplanes can land.

In fact, the greatest advantage of seaplanes is that the large investments required to build airports and runways are not required for their use. The West Coast of the USA and Canada (places like Seattle, Vancouver, Alaska, etc.) has a large number of seaplanes operating in calm stretches of seas and lagoons. There are seaplanes operating in the Florida area also.

There are seaplanes that operate from a water body to another or from a regular airstrip to a water body or vice versa. The latter type is versatile and will be of greater use in conditions in Kerala. For seaplanes that operate only on water, floats can be used as the landing gear where as for the other type both floats and normal landing wheels will be required. There are planes with both floats and wheels fixed and there are others where the floats are to be removed and wheels fixed. There is a third type that does not require floats, with bottoms designed for smooth landing on water with retractable landing gear for landing on normal runways. Such seaplanes are called flying boats.

2.7 SEAPORTS – OVERVIEW OF THE WORLD SCENARIO

There are a variety of different seaplane operations offering scheduled flights with high frequency to seaports up to flights on demand to landing places without or with limited infrastructure. Most of the operators use simple foot bridges sometimes in double use with boat bridges. The lower picture on the right shows the operating bridge from Loch Lemond on the Clyde River in front of the science centre in Glasgow.

Although the infrastructure on a final destination need not to be high sophisticated in case that the home destination is not far away and all service and maintenance activities may happen there. The larger operators as Harbour Air Vancouver, Maldivian Air Taxi and Kenmore operate from seaplane terminals fulfilling the IATA request for safe check-in with separate check-in areas and scanners and the same may be followed in this case as possible/feasible. (As per Fuesetra Report on Future seaplane traffic, version 1.0, available on Public domain on Internet)

While the Vancouver seaport has management and check-in buildings partly built by flexible materials (like tents); Maldivian has wooden buildings. The passengers embark and disembark by pontoon bridges which are also the mooring devices for the planes. On these seaports about 400.000 passengers take a flight to their destination each year.

These seaports are also equipped with fuel stations and small repair shops or in case of Kenmore with dock lift devices for bringing seaplanes into maintenance and overhaul hangars.

Other operators like Harbour Malta hired an existing harbour building as office and check-in building and built its own pontoon bridge equipped with fuel station and necessary safety devices as fire fighting equipment etc.

The largest seaport in the world is the company owned seadrome of Beriev. This port was built for testing the Beriev seaplanes in direct connection to the production facilities. It is the only certified hydroport in Russia for the time being. The complex includes certification of 

  • Hydro Port (airport) facilities
  • air traffic control
  • passengers transportation inside the hydroport
  • air, water and ground security
  • search and rescue means
  • Medical station, etc.

The Hydro Port is included in the register of the airports and airfields of Russia.
Water area used by the Hydro Port is registered in the marine documentation and is secured by the maritime authorities on notification.
Amphibians can taxi out of the water by a ramp. All necessary infrastructure as fuel stations, maintenance facilities, passenger terminal and offices are in direct neighbourhood. Beriev takes this lay out with minor dimensions as a sample for getting permissions for other locations. In total Beriev plans to open additional 22 seaports on lakes and rivers in Russia.

2.7.1 SEAPORT STRENGTHS

Smaller seaports can be realized on many water areas on shore, lakes or rivers without huge investments in concrete and buildings. Larger seaports need intermodal access and terminals, but investment and cost are much less than for airports or airfields for commercial land based operation.

2.7.2 SEAPORT WEAKNESSES

Feasibility of establishing water-dromes by small operators is a matter of concern.  With relatively low traffic, stand alone profitable model will happen only as the market matures contrary to established airports in the general aviation sector.

This process is also problematic because of missing standardized rules. Depending on special rules of a country or local administration several certificates of independent expert groups have to be presented.

Besides missing rules for the construction and operation of seaports there are nearly noindustrial off-the shelf products as terminals, foot bridges, pontoons or fuel devicesavailable. Most of the operators build and manage their own seaport facilities withlowest investments.

However, this hitch could be tide over with Governmental agencies taking up this burden by providing and maintaining waterdromes for dedicated seaplane operations.

2.7.3 SEAPORT OPPORTUNITIES

New materials, new designs and production technologies allow layouts of modern and effective seaports. Modular designs enable a stepwise enlargement equivalent to the business expansion.

These pictures show the possibility how to construct seaport terminals and pontoons by using modular elements. The terminal is built on a pontoon platform and can also be transferred to other locations by a towboat. Fibre materials avoid corrosion which is especially aggressive in salt water.

Retail and event business can be added by a layout with space for shops and restaurants. Most of the land based airports has such offers and make a remarkable profit.

Commercial seaplane operators have the responsibility for their seaport including passenger handling, docking (mooring), security, fuel management, load control, emergency procedures, rescue & fire fighting services and possibly third parties operations. Some services may be economically served by using tender boats which are equipped for refuelling, fire & rescue services and emergency procedures. For security reason a modern tank tender boat should be equipped with twin boat hull and interchangeable tanks.
Regarding economic seaplane operation for future seaplane commuter traffic infrastructure and seaports have to be optimized. The economic layout has a high priority. (Reference Fusetra Report on Seaplane traffic, version 1.0)

But as far as Kerala is concerned, we may introduce some out of the box alternatives making best alternate use of available water based tourism facilities of God’s Own Country.

CHAPTER  3 - TARGET MARKET

3.1 COMMUTER MARKET SEGMENT

Seaplanes have following market segments -

  1. Leisure and Fun Market – joy rides
  2. Semi Commercial Market
  3. Tourism & local Commuter Market Segment
  4. Special Markets

Among the above four segments, Commuter Market Segment remain the key focus of this study:
This category can be taken to consider aircrafts having seating capacity from 5 to 19 passenger seats. The traditional commuter traffic offers scheduled flights from smaller airports to Hubs or point to point connections between smaller airports. In the seaplane business three alternative variants of amphibian aircraft use in the local passenger transport are possible:

  1. The flight from the nearest land airport to the seaport (or the return flight).
  2. The flight between two water landing fields.
  3. The flight from the land airport to the seaport located in a far distance (e.g. transportation between the selected large airports and local tourist resorts).

These kinds of scheduled flights are only served in USA, Canada, Maldives and Malta, for the time being.

Maldivian Air Taxi (MAT) and Trans Maldivian offer flights from Male International Airport to more than 40 resorts on small islands without own airports. The flights are dependent on international flight arrival times and as such, scheduling can change frequently. MAT operates up to 150 flights per day with their 24 Twin Otters. Trans Maldivian operates 25 Twin Otters. Beside the commuter flights both companies serve sightseeing, excursions and special charter flights even in a VIP seating configuration.

In Vancouver Harbour Air Vancouver including West Coast Air (HAV) connects besides others Vancouver city with the city of Victoria on Vancouver Island with scheduled flights. With flights each twenty minutes nearly all over the day these flights are used by business and tourist people. Additionally HAV offers flights to other 8 destinations around Vancouver Bay with its fleet of Beaver, single and twin Otters. HAV owns more than 50 seaplanes and operates during April to October only.

Kenmore Air is flying an eclectic mix of piston Beavers and turbine Otters and Caravans, landing passengers on glaciers, lakes and harbors among the mist-shrouded fjords and islands of the U.S. and Canadian northwest. Beside some scheduled flights to Boeing field and some islands Kenmore offers charter flights to more than 100 destinations and special excursions as whale watching flights or flights to kayak tours also in cooperation with international hotel groups.

The majority of the offered flights to external destinations have a flight time between 15 and 45 minutes with a range of about 30 to 220 km.

Tourist companies see an additional need for longer ranges (with more comfortable planes) for bringing tourist from major populated areas directly to tourist destinations.
Harbour Air Malta was pushed by the local tourist offices to expand its routes to mainland Italy. Many Italian people have a secondary residence at Malta. HAM just got the permission for expanding its business to mainland Italy and Sicily.

Successful companies offer a variety of services beside scheduled commuter flights. Companies operating in this market segments mostly use the DeHavilland models Twin Otter (50 out of 350 A/C are equipped with floats), Single Otter and Beaver as well as the Cessna Caravan (about 100 out of about 1200 are equipped with floats).

3.2 MARKET STRENGTHS

It is a niche market with local aspects and particularity. Therefore only a few operators are on the market with a low competition worldwide but that too is not there at present in the case of India. The opportunities give Newcomers a good chance to start a successful operation and business, at least at the beginning.

3.3 MARKET  WEAKNESS

The general acceptance of seaplane operation within the population is low. On the one side the kind of operation is not really well known because of the few operators and on the other side the existing commuter propeller planes (most are unpressurized) have a want of acceptability.

In case of starting new operations with point-to-point destinations over longer ranges (more than 300 miles) the competition with low cost carrier will force low fare prices which will reduce the commercial success.

For medium ranges a competition with ferries and road transport may occur. While tourists flights are nearly without competition, scheduled flights and off-shore regions are highly competitive with ferries and road transfers. Harbour Air Vancouver and Harbour Air Malta operate in that competitive area. The success of these companies is achieved by a relative low ticket price and a high time saving in comparison to boat transfers.

General weakness is the limited weather capability which is more sensible in comparison to land based flights.

CHAPTER 4 - REGULATORY REQUIREMENTS

4.1 DGCA REQUIREMENTS

The regulations for these operations have been laid down by the Director General of Civil Aviation (DGCA) in Civil Aviation Requirements (CAR). A list of the CARs applicable to seaplane operations is given below:

  1. CAR Section 3 Series ‘C’ Part III or Part V for obtaining Non-Scheduled Operators’ Permit (Passenger) or a non-scheduled operators’ permit to undertake charter operations.
  2. CAR Section 3 – Air Transport Series ‘C’ Part IX for operational and airworthiness requirements for seaplane operation. This CAR deals with airworthiness requirements of aircraft, pilot qualification & experience requirements, operational requirements including preflight, passenger briefings, use of seatbelts and shoulder harnesses, safety requirements for take-off and landing areas, requirements for floating platforms, site selection, size of water runway, approach and departure paths requirements, transfer of passengers, other aids, right-of-way rules, permit for seaplane operations, etc.
  3. CAR Section 2 Series ‘O’ Part II on Operation Of Commercial Air Transport – Aero planes lays down the additional equipment required to be fitted on seaplanes in addition to preflight inspection of seaplanes, oral briefings for seaplane passengers, use of safety belts and shoulder harnesses in seaplanes, escape/egress in water after capsizing, water survival, and flotation gear required for seaplane occupants.
  4. CAR Section 7 – Flight Crew Standards Training and Licensing Series ‘B’ Part XVI regarding seaplane rating for pilots

Detailed CAR enclosed in Annexure – 1

4.2 OTHER AUTHORITIES

Following mandatory clearances are required to be obtained from the following authorities before introducing Seaplane services :

  1. Ministry of Defence
  2. Ministry of Environment and State Department of Environment as  applicable.
  3. Local Body (under whom the Site/ area belongs)
  4. Department of Forest if waterdromes are located in forest areas.

Beside the above clearances, an agency is also required to liaise and obtain no objection certificate to import and operate Seaplane in specified location(s).Inspection of all locations is mandatory by DGCA and BCAS officials as required will also be applicable.

CHAPTER 5 - AIRCRAFT TYPE

5.1  AIRCRAFT TYPE

As per prevailing situation globally, mainly Cessna and DeHavilland Canada aircraft are used for commercial seaplane operation. Almost all aircrafts are land based aircrafts converted to seaplanes by adding floats. The smaller operators use Cessna Series 180 and 210 or some derivates (205, 206, 207, etc.). All these aircrafts were designed about 40 to 50 years ago. Some are still in production and some were upgraded with modern avionics or engines. The basic airframe structures of these seaplanes are built out of aluminium with bolts, hinges and bearings made out of steel to withstand the heavy loads. These dissimilar metals generate an electrochemical process where the aluminium becomes the reactive anode and the steel becomes the cathode, and it is all conducted by the electrolyte water. The more salt in the water the better the conductive properties fuelling corrosion. The larger planes (as Cessna Caravan, Twin + Single Otter) have the same design principles and the same problem. The corrosion causes financial impacts for the operator because of short inspection periods and low life time of some parts.

Corrosion may be avoided by using fibre material for the basic structure. Viking bought the designs and design rights for the Otter and Beaver aircraft family from Canadair/de Havilland. Viking brings a new generation of Twin Otter aircraft to the market but despite of some major changes using fibre materials the basic design principles are unchanged.

Beside the aircraft aluminium floats have the same disadvantage. For the larger planes “Wipaire” is the only company producing floats for the Twin Otter and the new Kodiac plane. These floats are metal floats, as well. For smaller aircraft like the Cessna planes the company “Aerocet” has successfully developed fiber floats and increases the market share permanently. This company intends to widen their products to larger planes as well.

The flight performance of float based seaplanes is limited because of the additional weight and drag generated by the float system. Limitations in payload and/or range are significant.

The main disadvantages of the old designs are that they are partly out of production with higher spare parts and maintenance cost in comparison to modern aircrafts. For instance, the largest manufacturer of aircraft floats require 25 and 50 hourly checks on their floats, very simple checks that involve inspection and lubrication. All other checks on the floats are 100 hourly. The operator had to return the aircraft to its maintenance base every 25 hours; sometimes twice a week in peak season, to have these checks performed.

Recently new flying boats, the Beriev 103 and the Dornier Seastar, were developed with basic structure from fibre material. But both planes do not have a market share in the commercial business, so far.

5.2 AIRCRAFT STRENGTHS

The only strength of the existing seaplanes is the product price for most of the commercially used aircraft as Cessna and Otter Series because of the huge number of produced aircraft and a strong second hand market based on lot of emerging markets. These markets are basically evolved out of tourism needs or local transport needs and non availability of sufficient land for Greenfield airstrips.

5.3 AIRCRAFT WEAKNESSES

The existing float planes are not competitive comparing to state-of-the-art aircraft designs - neither in its performance nor in its cost effectiveness. The seat layout and the available space for luggage is not really passenger friendly. The maintenance cost is high and spare parts have sometimes long lead-times.

The operation with float planes is generally limited in rough waters. They can operate to a sea state 2. This includes strong restrictions in off-shore regions and operation in strong wind conditions.

6.4 OPERATIONAL REQUIREMENTS

6.4.1.1 PILOTS

6.4.1 REGULATORY REQUIREMENTS

Well qualified and experienced pilots as per existing fixed wing norms are required initially until seaplane related changes can be factored in by the regulating authorities which is expected to take much time.

6.4.1.2 SEAPORTS AND TAKEOFF/ LANDING ASPECTS

Operations to licensed aerodromes fall under normal legislation provided they are within the operating area stated in the Operations Manual and Air Operator Certificate (AOC) whereas the same may not be the case for water landing sites.

6.4.1.3 All flights shall be operated in accordance with the Manufacturer’s/Operator’s Operations Manual.
6.4.1.4 Night Operations and operations under IFR conditions are NOT permitted to water aerodromes.

6.4.1.5 ENVIRONMENTAL IMPACTS

Given the fact that in Kerala, seaplanes will be operating with the regular airports as base stations wherein the fueling and maintenance are envisaged ensuring that no undesirable impact to the local environment of the waterdromes happens.
The turbulence and other possible impacts of seaplanes are far lesser than those created by conventional speedboats and outboard engines, which are commonly used in such locations in Kerala.
Since we are proposing to use conventional houseboats for frisking and boarding etc., no other new/additional infrastructure is being developed/constructed. Hence any undesirable impact on topography of local environment is also avoided.


a) AIR AND WATER POLLUTION

Once the aircraft lifts off the water, and until such time as it alights back on the water, the environmental effect is identical to any other aircraft, as subject covered by numerous environmental studies.

Only few studies have been completed to assess the seaplane environmental impact anywhere in the world and in many cases these are independent studies carried out by private seaplane operators. The most inclusive and unbiased is probably an investigation conducted by US Army corps of Engineers (USACE).
The outcomes were:


Air Quality

No Impact

Water Quality

No Impact

Soil Quality

No Impact

Wildlife

No Impact

Fisheries

No Impact

Hydrology

No Impact

It is difficult to gauge the number of local flights versus the number of surface marine vessel movements, so it is futile to compare carbon emissions from a seaplane to those of marine traffic.Consideration anyway should be given to the fact that the number of boat movements within any given area greatly outweighs seaplane movements in this area. Thenext gen aircraft propulsion generation systems are having low noise and carbon emission levels. Further, most seaplanes operate with turbo-prop engines, which use JetA1 aviation fuel which does not contain some of the more volatile compounds found in many marine engine fuels.

Attention should also be drawn to the fact that seaplanes do not discharge sewage or oily bilge water and are not treated with toxic anti-fouling paints unlike boats. Seaplane exhaust is emitted into the air, much above the water giving practically no water impact.

The only water discharge from a seaplane is a small amount pumped from the floats each day. This is water that may have leaked into the floats over a specific time, usually 24 hours. No other matter other than the water in which the aircraft has been operating would be pumped from the floats and hence no impact on the surrounding water.

No other substances are discharged from seaplanes directly into the water. The engines are not cooled through heat exchangers as in marine engines, and the excess fuel after engine shut-down is collected in the accumulator specifically designed for this purpose. This accumulator is emptied on a regular basis to prevent water pollution.

There are no toilets on existing seaplanes, so no waste matter would be discharged into the water from this source. Also, there are no arrangements like restaurant/kitchen (as in case of boats and ships) there is no possibility expected for any waste to be discharged directly into the waters.
As brought out above, seaplanes in Kerala are proposed be operating with the regular airports as base stations wherein the fueling and maintenance are envisaged ensuring that no undesirable impact to the local environment of the waterdromes happens.
It is due to the fact that seaplanes are environmentally friendly, they are widely used for surveillance purpose in various national parks and wild life sanctuaries across the world. This is a mark of acceptance that they are amongst the most environment friendly means of transport.

b) NOISE

The seaplane would for a short duration of time on each flight sector, produce a level of noise comparable to that of speedboat engines as given in the table below. The power required for take-off creates a noise level of some 75 dba only. However, this level of noise is for a very short duration when taken over a particular point. The positioning of the TOLA (Take off landing area) is in general arranged in such a way as to avoid over flying a built up area at low levels. The power settings for an approach are relatively low, resulting in a negligible noise factor.
If the noise level of the seaplane is compared to other pleasure or leisure water craft such as speedboats and Jet Skis, the noise level of the seaplane is shown to be well below these craft (see Table).
As already mentioned, flight operations involving seaplanes are at present only conducted in day light hours, which precludes possible noise levels of the annoying nature.

6.5    OTHER OPERATIONAL CONSIDERATIONS

For seaplanes to really take off there are a number of barriers that must first be overcome. This paragraph highlights the major threats that seaplane operation is facing today and the fundamental issues that need to be addressed:

  • Public perception of light aircraft safety may impact on the acceptability of seaplane transportation. However, it should be noted that in the UK there has not been a single reported accident according to their air accidents investigation branch (AAIB).Making passengers aware of emergency procedures associated with seaplane aircraft while on the ground then it will go a long way to addressing some of the public’s safety concerns.
  • It is a not-well known means of transport and it could seem to be difficult to use.
  • Lack of a minimum level of training and acceptability of Dock Operating Crew so as to be multifunctional with regard to, assisting in the arrival and departure of aircraft on pontoons or piers, passenger handling, as well as manning the requirements of Rescue and Fire Fighting activities.
  • Certification process for new seaplanes (Modification of existing, and already certified, planes should also be considered).
  • Air traffic is perceived as expensive in general and costs mayappear to be high especially at the beginning.
  • Corrosion resistance. Use of new materials or methods to help to alleviate, delay or fully prevent corrosion should be available in order to widen the number of solutions that can be chosen among, based on functionality, cost and ease of maintenance.
  • Seaplanes are still too much depended on the weather conditions.
  • There are ordinary means of transport used everywhere and people are used on them.
  • Prices of tickets could be too expensive for common journeys (because of operational costs including high investment cost for aircrafts &related infrastructure)

CHAPTER 7 – INFRASTRUCTURE REQUIREMENTS

The landing site being on water, can be shared with other activities –mainly water vessel operations- so does not have the need for an area of ground/water surface to be set aside specifically for aviation purposes other than the narked waterdrome during times of operation.
Depending on the size of the operation in the area, a pontoon for passenger handling and docking of the aircraft is required. The apron area for manoeuvring in the dock area at this is calculated as approx1.5 times the wing span, or 1.5 times the overall length of the aircraft whichever is the greater. The Take-off and Landing Area (TOLA) although of considerable dimensions, does not of necessity have to be closed off to other marine activities. A pilot approaching to land is well able to adjust his approach path to ‘fit in’ with other traffic considering the relative speeds of an aircraft to that of marine traffic. It is for this reason that we call it a take-off area as opposed to a runway. The seaplane is able to adapt to a runway direction within the TOLA to suit conditions and conflicting traffic.Furthermore a seaplane at take-off speed can stop in a much shorter distance that it would be able to on land.

7.1     AIRCRAFT

     Type of Seaplanes mainly in service across the world

7.1.1   RECOMMENDED AIRCRAFT TYPE

It is recommended that, Govt. of Kerala may introduce Seaplane operations with a medium capacity Aircraft with seating capacity of 9-10 passengers, which could be upgraded over a period of time to a 19-20 seater Aircraft. Type of Aircraft could be selected based on the traffic expected and Infrastructure to be developed. Based on the feedback of the service, a higher capacity Aircraft could be deployed in future.

7.2     SITE SELECTION

When selecting a site for water aerodrome and installation of floating platform, the following will be considered:

  • If the location of the proposed water aerodrome is inside protected waters
  • Depth of sea bed on the proposed water runway and the size of aircraft intended to operation.
  • Distance of water aerodrome from the servicing resorts and islands.
  • Maritime movements in the location,
  • Navigable airspace,
  • Effect on the surrounding community
  • Available length of clear and safe water runway strip with respect to the size and type of aircraft intended for use.
  • Unobstructed approach and departure paths for the type of seaplanes to be accommodated
  • Current flow, water level, wave heights and floating debris
  • Bird hazards

Note: Location shall be such that cross wind operations are kept to a minimum and downwind operations shall be avoided. In other words the landing and take-off areas should be oriented to permit operations into the wind. Nature Reserved designated marine areas and Fishing Grounds shall not be used for water aerodromes. The strip of water shall be free from large obstructing corals rubbles to a definite depth and located inside protected waters which are safe to use of landing/ take-off of a definite seaplane.
