VIRFuel vs Refuelling

VIRFuel is a fuel and weight calculation application designed for Boeing 787, Airbus A350/330 operations using the Sabre flight plan. The application is in metric tonnes and conforms to SOPs used for Virgin Atlantic operations. Fuel and weight data is inserted from the front page of the flight plan (the 'plan figures') and can then be updated with desired loads and actual figures from the final ZFW/loadsheet. Changes in zero-fuel weight calculate updates to trip fuel and suggest a new ramp fuel. Alternatively a manually entered ramp fuel, touchdown fuel or required extra fuel at destination will calculate updates to trip fuel and ramp fuel. At each stage a take-off weight will be updated and TODC/OPT weights calculated (a TODC buffer of 1T is used). For near maximum weight plans, Std and Aft CG RTOW weights can be provided to calculate a maximum possible ZFW & Ramp fuel combination. Fuel uplift calculations in Litres and USG with commonly used density units are available to ensure an indicated versus calculated fuel load within +/-1.5%. A representation of the Aircraft Fuel Book can be shown for the easy entry or cross-checking of log book entries. Finally, flight plan waypoint fuel checks can be updated for changes in trip fuel burn. Internal cross-checking is performed and aircraft type limits can be set using the application settings menu or from the plan input page. Engineers have the option to skip directly to the fuel uplift page. A 'swipe-to-reveal' calculator has time addition and unit conversion functions. A list of favourite airports can be maintained for which TAF and Metar reports can be downloaded from the NOAA ADDS service. The reports are crosschecked for format errors, download errors and time validity. A colour coded system will highlight wind/visibility/weather/cloud fields that may have operationally significant values. RMK fields are not comprehensively scanned for all decodes and runway states or local variations in format are not necessarily decoded.

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.
