Roadmap for Performance-Based
Navigation
• The FAA published the Roadmap in
July 2003
• Collaborative effort among aviation
industry stakeholders
– Performance-Based Operations Aviation
Rulemaking Committee (PARC)
• Aligned with FAA Flight Plan, ATO
Business Plan, OEP, and RTCA
• Updating December 2005 to reflect
lessons learned

What is “Performance-Based
Navigation”?
• Aviation authorities specify the aircraft capabilities and
performance requirements necessary to operate in a
given airspace or use a given procedure (instead of
specifying required technologies or specific avionics)
– RNAV is achieved through a combined use of aircraft navigation
accuracy, route separation and/or air traffic control intervention (e.g.,
via radar monitoring, automatic dependent surveillance (ADS), multilateration,
communications)
– RNP is RNAV operations with on-board navigation containment,
monitoring and alerting

Enabling Criteria, Guidance and Tools
(Completed)
• AC 90-96A
– Approval of U.S. Operators and Aircraft to Operate Under Instrument
Flight Rules (IFR) in European Airspace Designated for Basic Area
Navigation (B-RNAV) and Precision Area Navigation (P-RNAV)

Federal Aviation 8
January 19, 2006 Administration
Enabling Criteria, Guidance and Tools
(Completed)
• US RNP SAAAR Criteria (FAA Order 8260.52) was
submitted to the ICAO OCP as a model for
international criteria for RNP approach procedures
– OCP accepted the order in total
• A drafting group will adapt the order to be consistent with PANSOPS
• Intent is to publish this criteria as a stand-alone document
supplementing PANS-OPS
– The end state objective is to have mature criteria for introduction into
PANS-OPS at OCP/15 in the fall of 2007
• AC 90-101
– Approval for RNP procedures with Special Aircraft and Aircrew
Authorization Required (SAAAR)

Authorization Required (SAAAR)
– 1 public RNP SAAAR
– 4 special RNP SAAARs
– 1 special RNP Parallel Approach Transition (RPAT)
• Published/Implemented 25 RNAV Routes
– 21 high altitude (Q-Routes)
– 4 low altitude (T-Routes)

Atlanta RNAV Departure
Procedures
April 2005
• Approx 90% of 1350 daily IFR
departures are RNAV capable
• Structured “lanes” to en route
airspace
• Over 4,000 routine daily
pilot/controller voice transmissions
eliminated (30% reduction)
• Delta Airlines estimates $30M
annual savings
– Decreased taxi times
– Decreased departure delays
– Improved flight profiles
– Reduced distances

Palm Springs RNP Approach
January 2005
• Avoids non-precision approach
into a valley with mountainous
terrain
• Safety enhancement, with
guided, stabilized 3D path to
runway
• Reduced time & distance
(approximately 30 miles)
• Reduced minima, averting
cancellations & diversions
– 20 flights “saved” in first few weeks
of implementation
– A SAVE is a flight that would have been
canceled or diverted if the RNP
procedure was not available
