Reserve, open-time & MEL

LONG_CALL + SHORT_CALL with callout and no-contact tracking.

Track reserve crew as LONG_CALL and SHORT_CALL with callout and no-contact handling, so the desk knows who's available and who's been used. Reserve coverage lives in the same system as the lines it backs up. It replaces the reserve list kept on a separate sheet.

Drop / pickup / swap with planner approval; auto-approves when no FAR 117 bust.

Pilots request drops, pickups, and swaps from the open-time board; a planner approves, and a trade that creates no duty/rest violation can auto-approve so the desk isn't a bottleneck on clean trades. Every trade still runs the legality check. It replaces trip trades negotiated over phone and email with no legality backstop.

Category A/B/C/D deferrals with auto-rolling expiry; expired items ground the aircraft.

Open a deferral against an MEL item and it tracks by category A/B/C/D with an auto-rolling expiry; an expired deferral raises a dispatch banner so the aircraft doesn't fly on a busted item. It replaces the MEL binder reconciled by hand.
