Whats PBN?

Performance-Based Navigation RNAV & RNP

Whats RNAV? Area Navigation

Whats RNP? Required Navigation Performance

Area Navigation (RNAV) + (monitoring & alerting)

What about RNAV (GPS)?

RNAV (GPS) approach is an RNP approach RNP APCH

No change in titling approach procedures

No requirement for a new airworthiness approval!

RNP AR Terminology

RNP with Authorization Required PBN!

FAA Perspective Like Cat II & Cat III ILS

Aircraft Qual + Flight Crew Qual = Safe Ops

Qualification is not for every pilot/operator or OEM

Intended to provide specific benefits at specific locations

Ops approval requires Ops Specs, M Specs, LOA

AFM should not imply ops qualification

Recommend Note ops approval required

RNP SAAAR became RNP AR

Change in AC 90-101A harmony w/ICAO PBN Manual

March 2011 AIRAC cycle update to all pubs

RNP AR Operational Concept

Safety Assurance Philosophy

No change in hazard ID & mitigation TLS 110-7

Took advantage of existing airworthiness approvals

Applies to new airworthiness projects contact us!

Remain New Airworthiness & Ops Concepts

No published FAA guidance prior to AC 90-101 (2005)

Still evolving AC 90-101A & AC 20-138D

RNP AR Approach Operational Success Requires Close Coordination Across Disciplines

Applications of RNP AR Criteria

Approach minimums lower than existing minima

Increased arrival & departure rates for adjacent airports involved

Arrival capacity gains up to 50% over single runway operations

Arrival capacity gains up to 60% vs. single runway ops

Hundreds of runway ends

10 to 15 Top Airports
