CAASL Shifts its Office from Colombo to Katunayake

Civil Aviation Authority of Sri Lanka, which is located at No.4, Hunupitiya Road, Colombo 2 has started shifting its office to a new building located at 152/1, Opposite Radar Hill, Katunayake- Minuwangoda Road, Katunayake, with effect from 16.01.2018. It is expected that the office shifting process will go on for upto 31.01.2018 and consequently, the members of the public are informed that the services delivered by the CAASL are likely to be adversely affected. Hence it is advised to avoid the abovementioned period when seeking services from the CAASL.

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.
