Refuelling 2.2.3

This application offers a highly detailed and sophisticated tool for aircraft fuel calculations, featuring comprehensive error management to ensure accuracy. Its user interface emphasizes simplicity and efficiency, guiding users through essential data entry steps:

• Select the appropriate aircraft model
• Input the required ramp fuel
• Enter the remaining fuel onboard
• Tap 'Calculate' to process data
• The app then displays entries for the techlog and fuel chit for review

Data retention capabilities allow the app to remember previous inputs, facilitating verification of subsequent data entries—an advantage over basic calculators. The system supports an unlimited number of aircraft profiles, enabling users to customize parameters for various aircraft types and variants. Features include:

• Default specific gravity settings per aircraft for streamlined input
• An option to set preferences for Separate Tanks, particularly useful when an aircraft lacks a fuel totaliser to prevent manual addition errors
• Ability to display 'FULL' on fuel chits when wing tanks are fully fueled or show actual values
• Support for rounding calculations in 100 Kg/Lb increments for aircraft with three-tank refueling arrangements
• Inclusion of company-specific volumetric tolerances per aircraft to verify fuel weight and volume within designated limits—configured once for convenience

A visual feature enhances user experience: after calculation, tapping the Fuel Chit section reveals a pictogram illustrating the fuel distribution across tanks, along with total fuel requirements and uplift volumes.

The app can verify both fuel weight and volume against set tolerances, providing an added layer of validation when necessary. Error prevention is integrated at multiple levels, guarding against common data entry mistakes automatically.

This universal application is compatible with iPhone and iPad devices. Additional information on the developer's website confirms its broad usability and robust design suited for professional environments.
