Atlanta RNAV Departure Procedures
• 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)
• Validated model estimates of
annualized benefits are ~$39M

RNP SAAAR Approach Site Prioritization
• Single runway access and risk mitigation
• Predominantly future airspace de-confliction
Tier 3
• Regional capacity impact
• Access and risk mitigation enhancement
Tier 2
• Includes converting 2004/2005 specials to public
• Urgent capacity needs, with national impact
• Risk mitigation cases

RNP SAAAR:
KDCA
• First “public” RNP SAAAR, published 1 Sept 05
FAA Order 8260.52 criteria
Avoids prohibited airspace
Significantly improves RWY 19 availability in low visibility
