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.
Launching the first quarter of 2027.

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
How an operator uses this
When a pairing is about to be assigned, duty and rest legality is checked first, and an assignment that would bust the limits is blocked before it posts — not flagged after the line is built. Flight attendants get the same assignment-time check on the 121.467 regime, and a bargaining unit's stricter contract limits layer on top of the FAR floor so the scheduler enforces whichever binds tighter — a contract value can only tighten a FAR limit, never relax it. A live crew duty board shows duty used per crew member off shifts and the flight log, and the fatigue risk board blends documented duty load with self-reported sleep into a per-crew view where every score traces back to its inputs — deterministic and explainable, not a black-box prediction.
Illustrative — every screen reflects what's in your own data, nothing more.
