MEL — minimum equipment list
Open a deferral against a minimum-equipment-list item and the system tracks it by category A/B/C/D with an auto-rolling expiry; an expired deferral surfaces a dispatch banner so the aircraft doesn't fly on a busted item. It replaces the MEL deferrals tracked in a binder.
Launching the first quarter of 2027.

Who it's for
The dispatch desk that has to keep an aircraft off a busted deferral and wants the MEL clock running in the same system it already works from.
What it replaces
The MEL deferrals tracked in a binder, with the category clock calculated by hand.
What mel — minimum equipment list gives you
- Deferrals tracked by category A/B/C/D
- Auto-rolling expiry per deferral
- Expired item raises a dispatch banner
Category A/B/C/D with auto-rolling expiry
Open a deferral against a minimum-equipment-list item and the system tracks it by category A/B/C/D with an auto-rolling expiry, so the clock on the deferral runs itself rather than being calculated in a binder. Pick the category and the system applies the auto-rolling expiry for it.
- Deferrals tracked by category A/B/C/D
- Auto-rolling expiry per deferral
Expired items raise a dispatch banner
When a deferral rolls to expired, it surfaces a dispatch banner so the aircraft doesn't fly on a busted item. The deferral and its deadline live in the same system the dispatch desk already works from, so the expiry is seen before the aircraft flies rather than tracked in a binder.
