  1. BENEFITS OF FLIGHT ACTIVATION MONITORING Hans Koolen EDITION 16/01/2013

  2. FAM - SUMMARY The CFMU has developed and implemented Flight Activation Monitoring (FAM) – a tool which: • Monitors flights that should have departed (monitors ETOT/CTOT) • Takes action on these flights through an internal to CFMU update of the Take-off time (internal shift) , as to improve the forecast. • Suspends them, after a time parameter unless a message, which confirms that the flight is airborne or delayed, has been received in the meantime. • Informs the AOs and local ATC of the suspension, enabling them to react.

  3. DEPARTURE MONITORING In August 2007: • 67% flights are monitored. • 18.5% are updated. • 533 flights suspended. • 286 updated by AO after suspension • 108 never updated  Ghosts. • (139 airborne when suspended) Flight Activation Monitoring (FAM) increases accuracy.

  4. AOs UPDATE FLIGHT PLAN Within 10 min after reception of FLS: • 48% are updated by DLA or CHG. • 12% are cancelled (21 flights). 222 flights are updated by AO After suspension

  5. DEPARTURES WHEN SUSPENDED • 70% (90 flights) are recorded airborne within -5 min, +10 min. • CPR/FSA/DEP late, over-flights, runway change, local conditions. 120 flights departed while being suspended

  6. IMPROVED FLIGHT PLAN ACCURACY • FAM leads to improved flight plan data due to a change in flight plan updating behavior: • More DLA messages • 1.5% overall increase in number of DLA messages • 6.5% increase for major monitored airports • Improved EOBT accuracy (for non regulated flights) • Slight change for early departures • 1.2% overall reduction in number of late departures • 2.1% reduction in late departures for major monitored airports • Less ghost flights due to more CNL messages. • Slight increase in number of CNL messages • 1% increase in CNL messages for major monitored airports.

  7. CONCLUSIONS • The main adverse effect of FAM are the approximately 100 flights recorded as departing while being suspended; • It is due to several reasons including late messages, local problems, incorrect taxi-times etc; • The main impact is unnecessary message. • The main benefit of FAM is the improvement of the short-term prediction of the ATFCM situation (around 4000 flights are updated although the coverage is still below 70%). • It is also a reminder for flight plan update and a way to reduce the impact of ghost flights.
