EASA FTL calculator
Enter your local report time and the number of sectors. You get the maximum daily flight duty period, the latest time it allows and the minimum rest after it. Nothing you type leaves this page.
Basic maximum without extensions, in-flight rest or split duty. Your airline's operations manual may hold approved variations, and the authority that oversees your airline (EASA, UK CAA, SHGM) is the one that counts. Check it before you rely on a number; this page is a reference, not an operational tool.
How the maximum FDP is set
Under ORO.FTL.205(b) the basic maximum daily FDP depends on two things: the local time you report, in the time zone you are acclimatised to, and how many sectors you fly. The best case is 13 hours for one or two sectors reporting between 06:00 and 13:29. Each sector from the third takes 30 minutes off, down to a floor of 9 hours. Afternoon and evening reports shorten the day in 15-minute steps; reports from 17:00 to 04:59 start at 11 hours.
If you are in an unknown state of acclimatisation, a separate table applies. It starts at 11 hours whatever the report time.
Maximum daily FDP, acclimatised crew
Hours:minutes by local report time (rows) and sectors (columns). The row for the time you entered is highlighted.
Minimum rest
ORO.FTL.235 sets the minimum rest before an FDP. At home base it is at least as long as the preceding duty period, or 12 hours, whichever is greater. Away from home base it is at least as long as the preceding duty, or 10 hours, whichever is greater, and must include an 8-hour sleep opportunity. A recurrent extended recovery rest of at least 36 hours, including two local nights, is due at least every 168 hours.
Cumulative limits
- Duty: 60 hours in any 7 days, 110 hours in any 14 days, 190 hours in any 28 days.
- Flight time: 100 hours in any 28 days, 900 hours in a calendar year, 1,000 hours in any 12 consecutive months.
These are the limits people miss most often. A single duty can be legal while the week around it is not.
Doing this for every duty
Working it out by hand for one duty is fine. For a whole month you would have to track acclimatisation, the WOCL, rest after every sector and the rolling windows, and do it all again whenever the roster changes. Crewops reads the roster your airline already sends you (from the crew portal, a calendar link or a PDF) and does this for every duty, with the same tables as this page. For airlines that publish through NetLine/CrewLink or JetXBit, see how the roster reaches your phone.
Questions
Do UK CAA and SHGM use the same table?
The UK kept the EASA ORO.FTL structure after leaving the EU, and the Turkish SHT-FTL follows the same model. Operators can hold approved variations, so your airline's operations manual is the reference that applies to you.
What is the WOCL?
The window of circadian low: 02:00 to 05:59 in the time zone you are acclimatised to. Duties that touch it face tighter rules on extensions and count as disruptive schedules.
Does this cover FAA Part 117?
Not on this page. The Crewops app handles Part 117 as well.
