Aerodrome control service is provided by control tower at each airport to landing and departing aircraft within 10 nautical mile radius of the airport from ground to 3,000 feet. This service is currently provided at all the international airports in Cambodia, namely Phnom Penh, Siem Reap and Sihanouk. The service is also available at three domestic airports such as Battambang, Koh Kong and Stung Treng.
Approach control service is provided at the three international airports within 30 nautical mile radius from each airport from 2,000 feet to 10,000 feet. The service guides arriving and departing aircraft between the designated air route and the airport, ensuring that adequate spacing between descending and climbing aircraft is continuously maintained.
Area control service is provided at the whole airspace of Cambodia, called Phnom Penh Flight Information Region (FIR), from 10,000 feet to Flight Level 460. The service tracks aircraft within the airspace with standard separation and coordinates their movement with the neighboring FIRs.
Flight information service and alerting service are provided in Phnom Penh FIR for the purpose of giving advice and information useful for the safe and efficient conduct of flights and for notifying appropriate organizations regarding aircraft in need of search and rescue aid and to assist such organizations as required.

Airspace Management

 The ongoing increase of number of flights using Cambodian airspace has resulted in the considerable concern over the congestion and limitation of airspace available for the users with much regard to safety. Airspace management has been established for the management of airspace with the aims of boosting efficiency of airspace utilization and increasing capacity of flight handling while at the same time enhancing safety.
Airspace management is also performed to safeguards aircraft from activities that may pose hazard to the safety when they are carried out in close proximity to airports or controlled airspace. These activities include balloon release, parachute jumping, rocket firing, etc.
Airspace management involves the arrangement for airspace by adjustment of route structure or sectorization of airspace with a number of methods as the following examples:
 
     
  • Using Performance Based Navigation (PBN) technology to develop uni-directional parallel Area Navigation (RNAV) routes in order to increase capacity and safety of flight handing and reduce the workload of air traffic controllers and pilots.
  • Redesign of air traffic control sector to meet with particular conditions of air traffic at a specific period of time.
  • Coordinating and sharing of information with appropriate military units for the flexible use of airspace during military operations to ensure the smooth conduct of the operations while maintaining safety and regularity of civil aircraft.
