  • FOREWORD The purpose of this brochure is to provide Airbus aircraft Operators with the agreed interpretations of the currently applicable RNP, RNAV and RVSM regulations. Should there be any discrepancy between the information provided in this brochure and that published in the applicable Flight Manual, MMEL, FCOM and SB, the information in the latter publications prevails unless otherwise approved by the national operational authorities. This brochure is designed to provide recommendations, which satisfy RNP, RNAV and RVSM, operational and certification requirements, in order for airlines to obtain operational approval from their national operational authorities. All recommendations conform to current regulatory requirements, and are intended to assist Operators in maximizing the cost effectiveness of their operations. We enc ourage you to submit any suggestions concerning this brochure, or any questions concerning the information to: Flight Operations Support & Line Assistance (STL Dept.)

  • 1. INTRODUCTION Traffic density is limited by aircraft vertical and horizontal separations, imposed by current navigation procedures associated with the performance of ground and airborne equipment. Due to increased traffic in specific areas, airspace is becoming saturated. This necessitates a reduction in aircraft separation while maintaining at least, the equivalent level of safety. Recent navigation systems offer the required navigation performance to achieve this objective, in conjunction with increased routing flexibility. Aircraft separation reduction with required level of safety requires the aircraft manufacturer, airspace administrators and Operators to demonstrate compliance with new standards referred to as: Required Navigation Performance (RNP), and Reduced Vertical Separation Minimum (RVSM). Another modern navigation trend involves the development of instrument procedures that are not based on conventional radio navaids. This type o
