RNP SAAAR - Background
On many destinations, opportunities exist in Approach, and
Missed Approach
–For Lower RNP values
–For Curved Approaches / Missed Approaches
Opportunities provided to Operators satisfying SAAAR
(Special Aircrew and Aircraft Authorization Required)

Airbus RNP Operations 17 Implementing RNP, October 4-5 2005
RNP SAAAR - Background
RNP SAAAR benefits:
Reduce minima
More efficient and Predictable Air Traffic Management:
– De-conflicting adjacent airports
– Better access to simultaneous parallel runway or converging
runway approaches
Optimize noise abatement procedures in sensitive areas

RNP SAAAR constraints
RNP SAAAR constraints:
Operational evaluation of each instrument procedure
Special flight crew training
Specific operational approval
National Authorities need to approve FAA SAAAR
criteria or develop their own criteria

Airbus RNP Operations 24 Implementing RNP, October 4-5 2005
International standardisation - Current situation and perspectives
Instrument procedures design criteria:
ICAO RNP RNAV Procedure (PANS OPS) available for
RNP 0.3
- ICAO RNP SORSG meetings:
Objective : to standardize a new approach type for RNP < 0.3
Aircraft airworthiness and operational requirements:
EASA (European Aviation Safety Agency) aims at
standardisation across European countries and
harmonization with FAA
- AMC20-XZ in progress
AIRBUS intent is to be compliant with AMC 20 XZ
