Route Tracking Benefits
•Miles flown benefit
–Example: ATL
•Flight distance benefit found for ‘downwind’, or loop, departures
–Flights departing west and then looping back around to the east
•Up to 0.7 nautical miles per flight saved in favorable conditions
–VMC conditions, RNAV off the runwayBaseline: March 1Initial post implementation: May 3
2 month post implementation: June 29-30
