Flight Procedure Design
CATS is in charge of the design and maintenance of instrument flight procedures, both conventional and Performance-Based Navigation (PBN), such as instrument approach procedure (IAP), standard instrument departure (SID), standard instrument arrival (STAR) and air traffic services (ATS) route.
CATS ensures that the published procedures are maintained with standard obstacle clearance and that they are met with the users’ requirements. The impacts to the environment, such as CO2 emission and noise abatement, are also taken into consideration.
CATS has so far developed and maintained the instrument flight procedures serving Phnom Penh, Siem Reap Angkor and Sihanouk Airports and whole airspace of Cambodia. Those procedures include:
- Very High Frequency Omni-directional Radio Range / Distance Measuring Equipment (VOR/DME) approach procedures;
- Instrument Landing System (ILS) approach procedures;
- Required Navigation Performance (RNP) approach procedures;
- Standard Instrument Arrival (STAR) procedures; and
- Standard Instrument Departure (SID) procedures.
