Updated in 2025, the Commander’s Discretion Guide by ECA clarifies this critical safety & flexibility provision.
Here’s what you need to know:
Remember: Commander’s Discretion is a last-resort safety & flexibility buffer, not an operational aid for your airline.
ECA FTL expert Carsten Reuter answers pilots' questions on Commander's Discretion.
Question: In practice, Commander’s Discretion is often used to finish a duty and avoid an overnight stay — but how much operational flexibility was it really intended to offer? Where’s the line between smart decision-making and stretching the rules?
Answer: Commander’s Discretion was designed for exceptional use, in case of unforeseen events such as unexpected weather delays or slot issues that come up after reporting.
It’s not there to fix poor planning or save the company money by avoiding hotel costs.
If a crew is routinely expected to extend their duty day, that’s a sign the airline isn’t doing its job in terms of proper planning. That’s not on the pilot to fix.
And here's the bottom line: if you or your crew are already fatigued, using Commander’s Discretion isn’t smart decision-making. It’s a safety risk.
Discretion gives you flexibility, yes! But only when it’s safe, necessary, and truly unexpected.
Anything else is stretching the rules.
