Design of a new RNAV approach procedure

The use of area navigation (RNAV), based on the Global Navigation Satellite Systems (GNSS), brings several benefits to access remote airports not equipped with traditional ground based radio navigational guidance: it increases safety by providing precise guidance for pilots and therefore makes the approach easier to fly and reduces chances of controlled flight into terrain. RNAV approaches can further enhance the availability of the airport as well as flight efficiency.

Air Austral is a French commercial airline with headquarters and main-base in La Réunion. It operates scheduled services to Europe, Africa, Thailand as well as to a number of destinations in the Indian Ocean, including the island Ajouan of the Comoros.

On behalf of Air Austral, airsight designed a new RNAV instrument approach procedures to Ajouan’s Ouani Airport in accordance with ICAO PANS-OPS, ICAO PBN Manual and the guidelines of ICAO Document 9906 Volume I - Flight Procedure Design Quality Assurance System.

This project introduced Instrument Flight Rules (IFR) procedures for Air Austral to Anjouan Ouani Airport.
