Abstract

Required navigation performance authorization required (RNP AR) approach (APCH) procedures are a special form of approaches with vertical guidance (APVs) where tougher navigation system requirements in terms of accuracy, integrity and functionalities allow smaller obstacle clearance areas and the use of curved legs in all approach segments. That leads to very flexible approach design possibilities compared to other instrument approach procedures and becomes especially valuable at airports surrounded by limiting terrain and/or airspace. This paper guides through the development of an RNP AR approach on runway 15L at Isa Air Base in Bahrain. The establishment of instrument approaches on this runway has been complicated so far as the final approach would have led straight through the controlled traffic region (CTR) of an adjacent air base. We show that entering the CTR, which ends less than 3.3 NM before the runway threshold, can be avoided with an RNP AR approach by employing a curved leg in the final approach segment and the highest possible navigation accuracy of RNP 0.1 – two unique features of RNP AR APCH. We then fly and test the procedure in an Airbus A320 level D full flight simulator under the wind and weather conditions considered by the procedure design rules. The results show that the actual navigation performance met the required one, so that we can prove that our approach is safe to fly.
