Implementation of ADS-B Surveillance System in Sri Lanka Airspace

Preliminary Notice

This is to inform all aircraft operators operating in Sri Lanka airspace that steps are being taken for the implementation of ADS-B covering the entire Sri Lanka Airspace. Accordingly the aircraft operators will have to equip their aircraft suitably for the operation of aircraft in the respective airspace in which they plan to operate. The following is a short description of the ADS-B for the general information of those who are interested and concerned.

Implementation of ADS-B Surveillance System in Sri Lanka Airspace

Preliminary Notice

This is to inform all aircraft operators operating in Sri Lanka airspace that steps are being taken for the implementation of ADS-B covering the entire Sri Lanka Airspace. Accordingly the aircraft operators will have to equip their aircraft suitably for the operation of aircraft in the respective airspace in which they plan to operate. The following is a short description of the ADS-B for the general information of those who are interested and concerned.

ADS-B

ADS-B is one of the most important, underlying technologies to transform the country’s air traffic control system from the current radar-based system to a satellite-based system. ADS-B is bringing the precision and reliability of satellite-based surveillance to the nation’s skies.

Working Principle

ADS-B uses GPS signals along with aircraft avionics to transmit the aircraft’s location to ground receivers. The ground receivers then transmit that information to controller screens and cockpit displays on aircraft equipped with ADS-B avionics.

Benefits

ADS-B for the first time allows pilots to see what controllers see: other aircraft in the sky around them. Pilots are also able to see – and avoid – bad weather and terrain, and receive flight information such as temporary flight restrictions. The improvement in situational awareness for pilots greatly increases safety.

The improved accuracy, integrity and reliability of satellite signals over radar means controllers will be able to safely reduce the mandatory separation between aircraft. This will increase capacity in the nation’s skies.

ADS-B also provides greater coverage, since ADS-B ground stations are so much easier to place than radar. Remote areas without radar coverage at present will be covered by ADS-B.

Relying on satellite signals instead of ground-based navigation aids also means aircraft fly more directly from Point A to Point B, saving time and money while reducing fuel burn.

ADS-B will also reduce the risk of runway incursions. Pilots and controllers will be able to see the precise location of aircraft and properly equipped ground vehicles moving on the ground – even at night or during heavy rainfall.

Necessity

Radar technology dates back to World War II. Radar occasionally has problems discriminating airplanes from migratory birds and rain “clutter.” ADS-B, which receives data directly from transmitters rather than scanning for targets like radars, does not have a problem with clutter.

Radars are also large structures that take up a lot of space, are expensive to deploy and maintain, and require the Air Navigation Service Provider to lease the land upon which they are situated. ADS-B ground stations take up only 20 square feet, including the perimeter fence. Ground stations are the size of mini-refrigerators.

Aircraft Avionics Required

The CAA will issue shortly the Implementing Standards to be complied with by aircraft operators for implementing ADS-B across the national airspace system. Under the proposed system, operators would equip their aircraft with avionics based on the airspace in which they plan to operate. The Implementing Standards will specify the specifications of the airborne equipment required.

National Civil Aviation Policy (Draft)

The Airspace over Sri Lanka is a public asset which has enormous potential to contribute for its socio-economic development. With clear, consistent and farsighted policies in place, the country’s airspace can be made busier and more productive with numerous activities that would demand a variety of ground support, services and resources triggering the country’s growth engine to spin faster producing wider socio-economic benefits. It is with above the objective in mind, that the National Policy for Civil Aviation has been drafted at the instruction of the Hon. Minister of Transport and Civil Aviation and under the guidance of the Hon. Prime Minister’s office, in close coordination and consultation with a representative group of all key stakeholders involved in aviation, setting out the overall objectives of the Government for civil aviation and the high-level policies that should be used to achieve those primary objectives on midterm and long term basis.

One of the main objectives of the proposed National Civil Aviation Policy is to improve the air connectivity enhancing the accessibility to any part of the country from any corner of the world so that Sri Lankan community may enter and compete successfully in the globalized air transport market for economic growth opportunities. Accordingly, the draft civil aviation policy framework proposes opening up of Sri Lanka’s skies to the rest of the world for international commercial traffic on the basis of reciprocity aiming at enhanced connectivity and accessibility. Also the draft National Policy encourages private sector to invest in the development of aviation infrastructure including construction, operation and maintenance of civil airports. It also proposes permitting local private airlines that satisfy the applicable international safety and security requirements to operate international commercial scheduled passenger flights in competition with foreign carriers aiming at securing and consolidating the country’s share international air transport market.

The draft National Civil Aviation Policy document deals with a variety of subjects in greater detail. 

  •    International Air Transportation
  •    Custom Duties
  •    Taxation applicable to International Airlines           
  •    Domestic Air Services
  •    Maintenance, Repair and Overhaul Organizations (MRO)
  •    General Aviation
  •    Stakeholder Participation in Aviation Development
  •    Designation of Airspace for Special Use
  •    Off-shore operations
  •    Airport Infrastructure
  •    Airport Master Plans
  •    Air Cargo Transshipment
  •    Land Use Planning
  •    Air Space Management
  •    State Aviation Safety Programme (SASP)
  •    Aviation Security
  •    Civil-Military Coordination
  •    Facilitation at Airports
  •    Human Resources Development
  •    Public Private Participation and Investment Promotion
  •    Consumer Protection
  •    Regulation of air cargo industry
  •    Access for Persons with Reduced Mobility and Special Needs
  •    Multi-Modal Transportation
  •    Environmental Safeguards
  •    International Conventions
