Flight Duty Calculator

Let an app compute your flight time limitation. 

This app computes the flight duty limitation and minimum rest time according to EU-Ops subpart Q, which is superseded by the EASA regulations. Hence this app can now be downloaded for free and can be used for reference. Please use our app EASA-FTL which implements the current regulations.  


Stop these endless discussions with crew-control and avoid these embarrassing violation reports in future, because you inadvertently busted your duty limit.

Flight Duty Calculator is a small and easy to use app which helps you to determine the maximum allowable flight duty period and the minimum rest you need after that duty.


Key features

  • easy and intuitive to use
  • calculation according EU-Ops subpart Q
  • flighttime extension included in calculation
  • Window of Circardian Low (WOCL) included in calculation
  • shift due to the difference between local time and UTC is implemented
  • effect of the place of first departure (homebase or not) is implemented
  • no ads


Split duty times are to be implemented by local authorities, as well as extensions due to pilots decision, so they are not considered in this app. However, we would be happy to develop special versions for companies or persons, so please contact us if you need special features implemented.

If you are flying under an Austrian AOC, you can use the Austrian edition "Flight Duty Austria" which implements the extension according to AOCV in addition to the Eu-Ops regulations. "Flight Duty Austria" can be found in Google Play.

If you are flying under FAR part 121, you can use the FAA edition "Flight Duty Calculator (FAA)" which implements FAR part 117. "Flight Duty Calculator (FAA)" can be found in Google Play.

Please be aware, that local regulations and company procedures can further restrict the regulations, so never forget, that you as pilot are ultimately responsible for acting according to the regulations.

This app exists in 2 versions, a full version, which costs a very moderate amount of money, and a free Light version. The free version is not able to compute your minimum rest time, but it will compute your max flight duty time accurately. The Light version is currently not available for Apple devices.
