MEL — minimum equipment list

How an operator uses this

Each pilot's recurrent training and currency sit on a timeline sorted by what expires next, so the Director of Operations sees the next cliff at a glance instead of answering for an expired endorsement after the fact. Before assigning a trip, the desk reads legality off a live crew duty board derived from shifts and the flight log, and an open MEL deferral that's rolled to expired raises a dispatch banner so the aircraft doesn't fly on a busted item. The fatigue risk board blends documented duty load with self-reported sleep into an explainable view — deterministic, traceable to its inputs, not a prediction model — and a POI gets read-only Ops Spec access that expires on its own.

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