The main objective of this project is to improve the precision of the approach trajectories and to develop and implement fuel efficient and environmental friendly procedures for approach in this high density TMA airport. The new RNP APCH procedures will help increase the accessibility by means of RNP APCH to LPV minima procedures (using SBAS), in combination with LNAV and LNAV/VNAV minima for those operators not equipped with SBAS technology. These procedures will make operations at this site more efficient and profitable, thus enhancing the use of the airport and saving operational costs, both for aircraft and airport operators (AENA). Reduce the missed-approach rate when using non-precision approach runway headers for landing. Increase safety by enabling straight approach procedures when not possible by means of current navaids infrastructure. Reduce costs for Aircraft Operators (AOs) whenever an airport change must be done due to operational restrictions at destination airport. Enhance airports and AOs business types by means of allowing broader kinds of flying activities at the airports.
