Now with a visual countdown indicator for Flying Duty Time remaining and Latest On Chocks time within the limits of a selected Flying Duty.
MYdutyday is a Flying Duty calculator for Pilots and Flight Attendants, focused on the immediate Flying Duty Period, so is most useful to aircrew when schedules change at short notice, flights are delayed or when finishing a Flying Duty Period later than originally planned.
Built for UK CAA CAP371 Flight Time Limitations it includes schema for:
- Max FDP (Acclimatised)
- Max FDP (with Extension)
- Max FDP - Single Flight Crew
- Max FDP (Unacclimatised)
- Unknown Acclimatisation
- Unknown Acclimatisation (FRM)
Based on our original MyDutyDay app, released in 2011, this version adjusts Maximum Duty Time Limits according to Standby Time prior to Report Time, Split Rest in a Duty Day, In-Flight Relief for Seat and Bunk Rest, as well as correctly calculating the current Flying Duty Period according to planned or actual Report Time and the number of Sectors operated.
The main view shows the Maximum Flying Duty Period allowed, according to user input values, and a countdown display gives a clear indicator of the remaining Duty Time available while calculating the Latest On Chocks Time allowed before the calculated Maximum Duty Time is reached.
Post-landing, entering an Actual On Chocks Time will then calculate the next earliest Report Time according to the previously operated Flying Duty Period, ensuring you get the minimum required rest before reporting for the next Flying Duty.
Default values for Post-Flight Duties, Minimum Rest and Max FDPs for Seat and Bunk Rest are preset but can be customised for your own Operations Manual in the app Settings view.
DISCLAIMER: This app is built as a tool for calculating Flying Duty Times and should only be used as a guide. Always check your legal Flying Duty Limitations according to your own company Operations Manual Flight Time Limitation Scheme.
