Helicopter HEMS (Part 135) · Standby & crew

Fatigue risk board

A fatigue risk view blends documented duty load with crews' self-reported sleep and rest, with every score traceable to its inputs — deterministic and explainable, not a prediction model. On long standby rotations this replaces judging crew fatigue by feel.

Who it's for

Base leads and dispatch desks on long HEMS standby rotations who want a fatigue view they can point to and trace, rather than judging crew fatigue by feel.

What it replaces

Judging crew fatigue by feel on long standby rotations instead of reading a view the base can point to.

What fatigue risk board gives you

Blends documented duty load with self-reported sleep
Every score traceable to its inputs
Deterministic and explainable — not a prediction model

Duty load plus self-reported sleep

The fatigue risk view blends documented duty load with crews' self-reported sleep and rest, giving each crew member a risk score on long standby rotations. It replaces judging crew fatigue by feel with a view the base can point to.

Every score traces back to its inputs

The view is deterministic and explainable, not a prediction model — the same inputs always produce the same score. Open a score to see the inputs it traces back to, so a fatigue reading is something the base can explain rather than a black-box output.

How an operator uses this

A fatigue risk view blends documented duty load with crews' self-reported sleep and rest, with every score traceable back to its inputs. It is deterministic and explainable, not a prediction model — the same inputs always produce the same score. On long standby rotations it replaces judging crew fatigue by feel with a view the base can point to.

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

How it works

Fatigue risk board, step by step

Documented duty load and crews' self-reported sleep and rest feed the board.
Each crew member gets a risk score blended from those inputs.
Open a score to see the inputs it traces back to.
Read fatigue from a deterministic, explainable view instead of by feel on long rotations.

Questions

Fatigue risk board — frequently asked

Is HEMS crew fatigue tracked with AI?

No. The fatigue risk view is deterministic and explainable — it blends documented duty load with crews' self-reported sleep and rest, and every score traces back to its inputs. It is not a prediction model.

What feeds a fatigue score?

Documented duty load plus crews' self-reported sleep and rest. The same inputs always produce the same score, and each traces back to those inputs.
