Association information

The main function of CATS is to provide air traffic control services, both civil and military throughout the Flight Information Region (FIR) of Cambodia. The services provided are in accor-dance with international standards and regulations to ensure safe, convenient and expeditious air travel. Air Traffic Control Services of Cambodia are divided into 3 sectors as follows:

Aerodrome Control
The Aerodrome Control Services are provided at all airports in Cambodia including Phnom Penh International Airport, Siem Reap Angkor International Airport and all other domestic airports (i.e., Battambang, Stung Treng, Rattanakiri, Mondulkiri, Sihanoukville, Koh Kong.) where the control covers a radius of 10 nautical miles from each of these airports and from the ground up to the altitude of 3,000 feet.

Approach Control
The Approach Control Services are provided at Phnom Penh International Airport and Siem Reap Angkor International Airport. The responsibility covers an area within a radius of 30 nautical miles from each of these airports from the ground up to an altitude of 10,000 feet.

Area Control
Area Control Center consists of only 1 sector covering all airspace of the whole country of Cambodia. Its responsibility is the provision of air traffic control and flight information services throughout the Phnom Penh FIR, which starts from an altitude of 10,000 feet up to flight level 460. The service is provided continuously, 24 hours a day.
CATS is equipped with a modern Air Traffic Control radar system which can present aircraft's call signs, alphanumeric information of aircraft positions, altitudes, and ground speed. The system also displays airways, digital video maps of restricted and danger areas as well as other relevant data necessary for the control of air traffic.

At present, CATS has its radar equipment installed at Phnom Penh and Siem Reap international airports and provides radar coverage over the entire airspace of Cambodia.
Moreover, the pilot-to-controller air/ground communication on VHF is provided by radio transmitters/receivers installed within the CATS's compound in Phnom Penh and by remote-controlled radio equipment located at 2 other stations in Siem Reap and Strung Treng. The VHF coverage is consequently extended over the entire Phnom Penh FIR at all altitudes and down to 5,000 feet or lower.

In addition, CATS provides air navigation-aid services at all airports in Cambodia. The navigation-aid equipment includes NDB (Non Directional Beacon) and VOR (Very High Frequency Omni Range), which provide the pilot with directions to and from the airport, DME (Distance Measuring Equipment) provides the distance to airport.
