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.
