b'MSP Flights Delayed by ATC* 2009 - 2018 Figure A-2 Airfield Delay per Aircraft Operation The FAA uses ASPM results to create performance benchmarks When calculating the average delay per flight operation, delay isfor airports each year. Since 2005, use of ASPM data has been a 12,000 averaged by each flights taxi time and airborne time.
