Crew Duty Time Limits

Mission viability is restricted by FAA/EASA regulations limiting crew flight and duty hours, which can force mission delays or aircraft substitutions.

Decision Question

Does the mission schedule preserve enough crew duty time to absorb unanticipated operational delays?

Trigger Conditions

  • • Unanticipated delays consume duty time
  • • Overnight stay limits next-day departure
  • • Crew arrives late

Affected Mission Layers

Propagation Paths

  • ATC delay → Duty time consumed → Crew times out → Flight cancelled or augmented crew required

Failure Modes

  • • Flight cancellation
  • • Forced overnight delay
  • • Aircraft substitution

Unknowns (Requires Confirmation)

  • • Real-time crew duty status
  • • Augmented crew availability

Recovery Dependencies

  • • Augmented crew planning
  • • Schedule buffer
  • • Alternate crew sourcing
