The main objective of the Implementation Project is to implement new procedures for landing aircrafts using Required Navigation Performance (RNP) approach procedures with vertical guidance (RNP APCH) in the high-density Terminal Manoeuvring Area (TMA) of Amsterdam Airport Schiphol, as part of the Performance Based Navigation (PBN) implementation.
RNP APCH is an approach specification offering performance superior to conventional non-precision approach and without dependency on ground-based infrastructure. Instead, RNP APCH utilises the capabilities of the on-board navigation system to provide 3D guidance.

Specific objectives:
The Implementation Project specifically aims to deploy RNP APCH procedures to the remaining six runway ends at Amsterdam Airport Schiphol (EHAM) at runway ends 27, 18R, 24, 36C, 04 and 09. For each corresponding runway end, two RNAV approach procedures will be established:

• LPV (Localizer Performance with Vertical guidance) approach using the European Geostationary Navigation Overlay Service (EGNOS) system, aiming for CAT (Category) I minima;

• LNAV/VNAV (Lateral Navigation/Vertical Navigation) approach as present in large part of the fleet, with LNAV as reversionary mode.

• For RWY (Runway) 18R there will even be a third design, aiming at independence from RWY 27, possibly with RF (Radius to Fix) leg.

The Implementation Project will establish ATC (Air Traffic Controller) working methods and flight procedures considering the PBN equipped fleet mix.

Expected Results:
The following results are expected:

• RNP APCHs and operational procedures are designed,

• validation flights for the designed procedures are executed,

• the safety of the designed procedures is analysed,

• RNP APCH procedures are published in the National Aeronautical Information Publication (AIP),

• Air Traffic Controllers are trained,

• Operational use of the procedures is ensured.

Performance Benefits:
In terms of performance benefits, the following areas can be identified:

• Backup procedures are established enhancing operational sustainability;

• Independent converging operations will improve reliability in adverse weather conditions;

• Several runway ends will be accessible where the IFR (Instrumented Flight Rules) business case was not positive until now.

This project completes the implementation of Family 1.2.1 “RNP Approaches with vertical guidance” at Amsterdam Airport Schiphol. The withdrawing of existing non-precision approach procedures and the corresponding decommissioning of related nav-aids (radio beacons) for Amsterdam Airport Schiphol is part of another CEF Transport funded project named ""Performance Based Navigation procedures and rationalisation of Air Navigation infrastructure in the Netherlands"", action number 2016-NL-TM-0336-W, the RNP APCH procedures for Amsterdam Schiphol (in this IP) are not included in the scope of this action.
Publication and operational implementation of RNP APCH to RWY 22 is funded under Action 2014-EU-TM-0136-M (IP #107AF1: ""First phase of RNAV1 and RNP-APCH approaches Amsterdam Schiphol (EHAM)"") and of RNP APCH to RWY 06, 18C and 36R under Action 2015-EU-TM-0196-M (IP 2015_186_AF1: ""RNP approaches to three main landing runways Amsterdam Schiphol"")."
