Commander's discretion
The captain's authority to extend a duty or shorten a rest beyond normal limits for unforeseen events after report, after consulting crew.
Definition
Commander's discretion is the legal power of the pilot in command to exceed the normal flight time limitations when unforeseen circumstances arise at or after report — a technical delay, weather, a diversion — and it is safe to continue. Under EASA the maximum FDP may be extended by up to two hours (three with augmented flight crew) and a rest period reduced, but never below ten hours, and the commander must consult all crew on their alertness, record the decision and report it to the airline and, for larger extensions, the regulator. It can never be used as a rostering tool.
What it means for you
Discretion is the mechanism that turns a 13-hour legal day into 15, and it is exercised over you, not on your behalf, unless you speak up: the consultation is your moment to say you are too fatigued to continue safely, and no commander wants to extend with a crew member who has declared themselves unfit. Repeated discretion on the same pairing is itself reportable, so make sure the report is filed.
In practice
A British Airways 777 held on stand at JFK for a 90-minute ATC delay reaches the FDP limit before landing at Heathrow; the captain consults the cabin crew, extends under discretion, and the purser's report notes who was consulted and what they said.
