Part 121 · Duty, rest & fatigue
Fatigue risk board
The fatigue risk board surfaces a per-crew risk view that blends documented duty load with each crew member's self-reported sleep and rest, and every score traces back to the inputs behind it. It is deterministic and explainable — there is no black-box prediction model. It replaces judging crew fatigue by gut feel on long rotations.
Launching the first quarter of 2027.
Illustrative — every screen reflects your own data.
Who it's for
Crew desks and safety staff who want a traceable fatigue signal they can defend, instead of judging crew fatigue by gut feel on a long rotation.
What it replaces
Judging crew fatigue by gut feel on long rotations.
What fatigue risk board gives you
- Per-crew risk view from duty load plus self-reported sleep
- Every score traces back to its inputs
- Deterministic and explainable — no black-box prediction model
Duty load plus self-reported sleep
The fatigue risk board surfaces a per-crew risk view that blends documented duty load with each crew member's self-reported sleep and rest. It gives the desk a traceable signal it can defend rather than a gut-feel read on a long rotation.
- Per-crew risk view from duty load plus self-reported sleep
- A traceable signal the desk can defend
- Replaces judging crew fatigue by gut feel
Deterministic and explainable — no black box
It is deterministic and explainable: the same inputs always produce the same score, every score traces back to the inputs behind it, and there is no black-box prediction model deciding who looks tired. Open any score to see exactly what drove the number.

How it works
Fatigue risk board, step by step
Documented duty load and each crew member's self-reported sleep feed the score.
The board shows a per-crew risk view from those inputs.
Open any score to see the inputs it traces back to.
Use it as a deterministic, explainable signal — not a prediction.
Questions
Fatigue risk board — frequently asked
Does the fatigue board predict fatigue with AI?
No. It is deterministic and explainable — it blends documented duty load with crew members' self-reported sleep, and every score traces back to its inputs. There is no black-box prediction model.
What goes into a crew member's fatigue score?
Documented duty load plus that crew member's self-reported sleep and rest. Because every score traces to those inputs, you can see exactly what drove the number.

Deep diveMaintenance-station routing
Flags when a tail's due check won't reach a capable station before its limit. Advisory — it surfaces the risk, it doesn't block dispatch.
Deep diveCrew-base efficiency
Surfaces deadhead and out-of-base overnights so pairings can be built to originate and terminate at a crew member's base.
Deep diveWeighted efficiency score
A configurable weighted score (abstract points, lower = better) over deadhead, overnights, repositioning, and maintenance-fit slack — set your own weights.
Deep diveExplainable swap / re-base suggestions
Deterministic aircraft-swap and re-base proposals that improve the score — every suggestion shows its reasoning. Not AI, not a guaranteed optimum.
