Flight crewmembers at stations

Read the official rule

In plain English

Required flight crew must be at their stations during takeoff, landing and en route — except when away for flight duties or physiological needs — with the seat belt fastened, and the shoulder harness fastened for takeoff and landing if one is installed.

Key points

  • Be at your crew station for takeoff, landing and en route (except for duties or physiological needs).
  • Keep the seat belt fastened while at the station.
  • Keep the shoulder harness fastened for takeoff and landing if installed (unless it impedes required duties).

Common pitfalls

  • Loosening belts or harness too early on approach.
Summary: Required crew stay at their stations with seat belts fastened (and shoulder harness for takeoff/landing if installed), except when flight duties or physiological needs require otherwise.
