Part 121 · Duty, rest & fatigue

Crew duty board

A live board shows each crew member's duty used, derived from their shifts and flight log, so the desk sees who's running out of legal duty before assigning the next trip. It replaces reconstructing duty totals from paper.

Who it's for

Crew desks that need to see who's running out of legal duty before assigning the next trip, instead of reconstructing duty totals from paper after the fact.

What it replaces

Reconstructing each crew member's duty totals from paper.

What crew duty board gives you

  • Live duty used per crew member
  • Derived from shifts and the flight log
  • Who's running out of legal duty, before the next trip

Duty used, derived live

A live board shows each crew member's duty used, derived from their shifts and flight log rather than tallied by hand. Because the figure updates as duty is logged, the desk reads an accurate picture rather than a stale tally.

See it before the next assignment

Because the figure updates as duty is logged, the crew desk can see who's running out of legal duty before assigning the next trip instead of reconstructing totals from paper after the fact. It's the running picture the assignment-time legality check reads from, presented so a human can scan it.

How an operator uses this

A live board shows each crew member's duty used, derived from their shifts and flight log rather than tallied by hand. Because the figure updates as duty is logged, the crew desk can see who's running out of legal duty before assigning the next trip instead of reconstructing totals from paper after the fact. It's the running picture the assignment-time legality check reads from, presented so a human can scan it.

Illustrative — every screen reflects what's in your own data, nothing more.

How it works

Crew duty board, step by step

  1. Each crew member's shifts and flight log feed their duty total.

  2. The board shows duty used per crew member, live.

  3. Scan it to see who's running out of legal duty before the next assignment.

  4. Assign the next trip against an accurate, current picture — not a paper reconstruction.

Questions

Crew duty board — frequently asked

Where does the crew duty board get its numbers?

From each crew member's shifts and flight log. Duty used is derived live rather than reconstructed from paper, so the desk sees who's running out of legal duty before assigning the next trip.

Is the board current?

Yes. It's a live board — duty used updates as shifts and the flight log are recorded, so the desk reads an accurate picture rather than a stale tally.
