Administration 2
FAA’s Roadmap for
Performance-Based Navigation
• Collaborative effort among aviation industry
stakeholders
Performance-based Operations Aviation Rulemaking
Committee (PARC)
• Three Planning Horizons (updated version)
Near-term 2003 to 2006 (2006 to 2010)
Mid-term 2007 to 2012 (2011 to 2015)
Far-term 2013 to 2020 (2016 to 2025)
• Harmonization considerations
• Focuses on operational capabilities in:
En route domain
RNAV Q-Routes
RNAV T-Routes
Terminal domain
RNAV Standard Terminal Arrivals (STARs)
RNAV Standard Instrument Departures (SIDs)
Approach domain
RNP Special Aircrew and Aircraft Authorization
Required (SAAAR)
RNP Parallel Approach Transition

Administration 5
En Route
•RNP-2 Q Routes
•RNP-1 in selected areas high altitude
•GPS Direct and RNAV T Routes
•Lower MEAs on routes based on GPS
Near Term (2006-2010) Mid Term (2011-2015) Far Term (2016-2025)
Terminal
•RNAV SIDs/STARs at OEP Airports
•Controller Tools for Merging and
Spacing
•RNP-2/1 SIDs/STARs in busy
terminal areas
Approach
•Complete Standards for
Performance-based
Approaches
•Initial sites for Basic RNP
•25 RNP SAAAR per year
•300 LPV per year
•Standards for closely spaced parallel
and converging approaches
(e.g., enhanced surveillance)
Mandate RNAV
above FL350
En Route
•RNP-2/1 Q Routes and Airspace
•GPS Direct and RNAV T Routes
•Lower MEAs
Terminal
•RNP 2/1 and RNAV SIDs/STARs
•Merging and Spacing with Time of
Arrival Control
Approach
•Hundreds of Basic RNP, RNP
SAAAR, and LPV per year
•Standards for closely spaced parallel
and converging approaches
(e.g., improved surveillance)
Mandate RNP
above FL290
Mandate RNAV above FL180
and for arriving/departing at
OEP Airports
Mandate RNP in
busy en route and
terminal airspace
Explore need for
4D, data link, and
enhanced
surveillance
capability
mandates

Operations
•Optimized Airspace and
procedures based on
Required System
Performance
•4D Trajectory
Management
•Delegation of separation

Enabling Criteria and Guidance
• AC 90-100 U.S. Terminal and En Route Area Navigation (RNAV) Operations
Airworthiness, Operational Approval, Operating Procedures, and Training guidance for RNAV
Departure Procedures, RNAV Standard Terminal Arrivals, and RNAV routes
Currently in revision by FAA and Industry team to incorporate lessons learned and harmonize with
international developments
• Order 8260.52 United States Standard for Required Navigation Performance
(RNP) Approach Procedure with Special Aircraft and Aircrew Authorization
Required (SAAAR)
Written for approach procedure designers to develop public RNP SAAAR instrument approach
procedures
• Notice 8000.300 RNP SAAAR
