Enter as many aircraft as you like and set your own parameters! Incredibly detailed and sophisticated App with built-in error management. EASY TO USE - Ensure correct aircraft selected - Enter required ramp fuel - Enter remaining fuel - Press calculate! - Techlog and fuel chit entries will be displayed DATA RETENTION - Remembers information used - Allows subsequent data input verification, unlike a calculator UNLIMITED AIRCRAFT - Designed to allow entry of aircraft type-specific parameters for as many aircraft and variants as desired - Set default specific gravity for each aircraft for ease - Set a preference for Separate Tanks if your aircraft does not have a fuel totaliser to avoid mental addition - Elect to display 'FULL' on the fuel chit when the wing tanks are full or the actual value - Supports rounding for aircraft that refuel in 100 Kg/Lb increments when using a 3-tank arrangement - Add company-specific volumetric tolerances for each aircraft to verify fuel weight and/or volume is within prescribed limits - Only needs to be done once PICTORIAL - Once fuel requirements have been calculated, tap anywhere on the Fuel Chit section to see a pictogram of the aircraft showing fuel distribution in each tank along with total fuel required and total uplift required! VOLUMETRIC CHECK - If required, it is possible to check both fuel weight and volume are within set tolerance. ERROR MANAGEMENT - Guards against entry errors using aircraft data - Automatic Universal App. See Developer website. Designed for iPhone but works just as well on iPad.
EASA FTL Calc
This app calculates flight time limitations for cockpit and cabin crew based on EASA OPS rules. It accounts for various factors like duty periods, rest times, time zone differences, and disruptive schedules, simplifying complex calculations for pilots and cabin attendants.
- Cockpit and cabin limits calculation
- Flight duty period calculation
- Rest time calculation
- Time zone management via airport selection
- Support for disruptive schedules
- Roster import options

EASA FTL Calc helps flight and cabin crew calculate and monitor: • Cockpit and cabin crew limits • Actual and maximum Flight Duty Periods (FDP) • Latest on-block times • Duty Periods (DP) • Actual and minimum rest periods • Acclimatisation status • Commander’s discretion • Planned reduced rest • Disruptive schedules • Required local nights at home base • Extended recovery rest periods • Cumulative duty times for 7, 14 and 28 days • Monthly duty times The app takes into account: • Standby, airport standby and airport duty • Extended cabin crew FDP due to earlier reporting times • Delayed reporting • In-flight rest for cockpit and cabin crew based on the applicable rules • Split duty • FDP extensions • Planned reduced rest • Positioning • Time-zone differences • Company-specific minimum rest periods • Your assigned home base • Back-to-back operations You do not need to calculate or enter time zones manually: • Simply select an airport from the database • The time zone is determined automatically based on the airport and date For each rotation, you only need to select: • The airport where the rotation begins • The rest location after each duty day • The next reporting airport is automatically set to the previous rest location EASA FTL Calc is designed as a duty logbook, not as a flight logbook: • You do not need to enter every individual block time • The app does not manage cumulative block-hour limits • Imported flights may still be displayed for reference Separate cockpit and cabin calculations: • Reporting times may differ • In-flight rest rules are different • Your own limits are calculated using all available information • Calculations for other crew members may be limited because less information about their previous and subsequent rotations is available Rotation management: Rotations are stored automatically and displayed in a dedicated overview. The overview includes: • Flight Duty Periods • Duty periods • Rest periods • Separate calculations for cockpit and cabin crew XML import: • BA rosters only RosterBuster import: • Direct import from the server Direct import from other apps and websites: • NASImport • CrewLounge CONNECT • RosterworX • MyRoster for Crew by Lumabyte — sadly no longer available eCrew AIMS Dashboard import: If your roster can be downloaded as a .txt or .csv file, it can be opened directly in EASA FTL Calc. Because AIMS can be configured differently by each airline, occasional compatibility issues may occur. In many cases, these can be resolved. Calendar import: Roster data can also be imported from your calendar. Because calendar entries can use different formats and naming conventions, occasional compatibility issues may occur. In many cases, these issues can be resolved.

Verdict
The clearest difference is rating: EASA FTL Calc at 3.8 against Refuelling's 3.0. EASA FTL Calc also leads on ratings volume (5 vs 1). Refuelling's advantage is price ($4.99 vs $6.99) and iOS requirement (15.0 vs 17.0). On review sentiment, update cadence, ads and in-app purchases there is nothing between them.
