The radio navaid infrastructure supports the required Navigation Accuracy level

– It is not the Operator’s duty to verify the adequacy of radio navaid coverage

– Inadequate radio navaid coverage should be notified by NOTAM or on the instrument procedure chart ⇒ GPS required

GPS acceptable if TSO C 129A certified– All Airbus with GPS comply

Single or Dual RNAV system– Single system acceptable, unless flight path below area MSA

or/and (?) no radar coverage (TGL 10)– Should be stated on the instrument procedure chart

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)RNP RNAV or Containment Based RNAVprocedures

–Links RNAV airspace design to Aircraft Performance

RNP SAAAR benefits:Reduce minimaMore 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

Conclusions

A large part of the Airbus fleet has the capacity to benefit from cost-effective RNAV(GNSS) or RNP RNAV approach implementation

Airbus is already involved in RNP SAAAR projects with several Airlines

Airbus will anticipate the future developments of RNP RNAV Operations, and other approach and landing means, to optimize the Airbus aircraft capabilities through R&T projects such as Optimal (www.optimal.isdefe.es)

Conclusions

Deploy in priority P-RNAV and RNAV(GNSS) or RNP 0.3 RNAV straight-in (PAN OPS)

RNP SAAAR (or equivalent) to be used only when an operational benefit can be achieved

Develop ICAO standards similar to SAAAR, harmonized with FAA “Public” SAAAR

Harmonize regulations between Europe and USA
