• Why Flight Plan and ATFCM adherence?

Christian Faber Head of Investigation
2
The problem

• Traffic exceeds capacitiesby more than 10
  ATFCM "over delivery"

• Not flying at the requested flight level (RFL)
• Arriving in the sector earlier or later than
  planned
• Departing at times different from EOBT/CTOT
• Deviating from their original planned route

Network effect impacting SAFETY!

Example 2over delivery in Austria
16 flights flying higher than filed

Whats the effect

• Potentially excessive workload,
• Wasted capacity in some sectors,
• An overall lack of confidence in the accuracy of
  forecast traffic counts,
• Protective capacity reduction,
• Increased workload, stress or working conditions
  such that the ability of ATC controller may be
  significantly impaired and thus a safety issue.

Flight Plan and ATFCM adherence awareness
campaign

• Three main elements of adherence
• Adherence to requested FL (one of the main reason
  for over-deliveries)
• Adherence to Flow Measures, mainly CTOT (thus
  arriving too early/late in the sectors)
• Adherence to filed route (incomplete or incorrect
  ATFCM picture)
• Procedures and rules exist already

9
ICAO Doc 7030/4 (EUR)

• ATC is responsible for departure slot monitoring
  at departure aerodromes
• Aircraft operators shall inform themselves
  ofand adhere to current ATFM measures
• Any changes to the EOBT of more than 15 minutes
  for any IFR flight within the IFPZshall be
  communicated to the IFPS

10
Commission regulation (EC) No 1033/2006 (1st
January 2009)

• The operator shall ensure that the conditions of
  acceptance of a flight plan and any necessary
  changes thereto as notified by IFPS to the
  originator are incorporated into the planned
  flight operation and communicated to the pilot.
• The operator shall ensure prior to operation of
  the flight that the content of the initial flight
  plan correctly reflects the operational
  intentions.

What has been done?

• CTOT adherenceFollowing countries are/were
  involved or have been contacted regarding CTOT
  adherenceEB, LK, HE, LF, LG, LH, LT, EG
• OPS evaluationMaastricht and Rhein UAC
  operational evaluation of requested FL
• TrainingSkyGuide include subject in ATCO
  refresher training (MUAC plans to do the same)
• SystemSkyGuide system trial of identification of
  flights at differing RFL prior to ACC entry.

15
From awareness to improvements

• Continue awareness activities and assessments at
  local, regional and network levels
• Continue to address adherence issues at
  individual airports and ACCs with ANSPs, AOs and
  authorities concerned
• Best Practices (local initiatives, ATCO pilot
  training, etc)
• Trials, comparison exercises (routes filed versus
  flown) and simulations to show impact
• Adherence Day (see next slide)

16
Adherence Day
One day operational evaluation through full
application of adherence procedures

• Objectives
• Measure the effect of adherence to FPL and ATFCM
  measures
• Determine benefits arising from accurate
  EOBT/CTOT RFL with regard to sector counts
  (potential release of capacity)
• Improve the quality of FPL with regard to routes
  (incl. DCT) and FLs

17
Benefits of adherence

• reliable and accurate data for all involved
• improved predictability of traffic
• improved network demand-capacity balancing
• increased capacity
• increased safety
• flight efficiency
