In order to operate in high level airspace above FL290 and to utilize aircraft navigation systems that offer fully independent or satellite based flight navigation capability, both the aircraft and the flight crew must be authorised to do so by the CAACI.
The Designated Airspace Approval Certificate identifies the Performance Based Navigation (PBN) equipment installed on the aircraft that is approved for use on the aircraft and that flight crews have been trained to operate. Typical approvals include Minimum Navigation Performance Specifications (MNPS), Reduced Vertical Separation Minima (RVSM) and Required Navigation Performance (RNP).
Follow this link to apply for the Designated Airspace Approval. The approval is usually issued for two (2) years and its scope is determined by the PBN Equipment on board the aircraft along with the level of training received by the flight crew on that equipment.
