A recovery decision should come with its workings. Explore the model, compare the trade-offs, and replay the scenario that produced the result.

SIMULATED OPERATING DAY

RECOVERY
AT EVERY
CONSTRAINT.

The plan has to survive the next departure, the next assignment, and the next shift.

DUTY CLOCKS, IN CONTEXT

Follow flight time, duty periods, and rest windows alongside the affected aircraft rotation. A recovered schedule must work for the crew flying it.

A RULE BEHIND EACH DECISION

Inspect the implemented Part 117 checks and their inputs. Feasible and optimal are distinct solver outcomes, and the interface keeps that distinction visible.

REPLAY THE SAME DISRUPTION

Saved events, frozen weather snapshots, and a single-worker seeded solver make recovery decisions traceable in deterministic replay mode.

RECOVER THE WHOLE ROTATION

Weather, airspace restrictions, aircraft failures, and crew availability propagate through the schedule. Compare the consequences before choosing a plan.

DESIGNED AROUND THE DISPATCHER

CLARITY,
WHEN THE
PRESSURE IS ON.

“Let me replay the inputs and inspect the trade-off. A recommendation needs an explanation.”
