Whenever you need to refuel, just enter the ramp fuel, remaining fuel and alter the aircraft's default specific gravity (if required) then press Calculate. That’s it!

As well as making life easier, compared to using a calculator, it significantly reduces the chances of errors in fuel calculations thanks to built-in error management. Additionally the App remembers all the information used. A very useful refuelling App for pilots all over the world.

This App is designed to allow the entry of aircraft type-specific parameters for as many aircraft and variants as you like. Whatever aircraft you operate, just enter the type, maximum total fuel capacity, wing fuel capacities, along with the lowest likely ramp fuel and remaining fuel to guard against entry errors. This only needs to be done once. You can even set your own default specific gravity for each aircraft to save you the trouble of entering this every time and even set a preference for Separate Tanks if your aircraft does not have a fuel totaliser and you can't be bothered adding the tank quantities in your head! You can also add company volumetric tolerances for each aircraft if you are required to verify that the fuel weight and/or volume needs to be within certain company limits.

Techlog entries will be displayed as will the fuel chit information using the information entered. You can elect to display 'FULL' on the fuel chit when the wing tanks are full or the actual value.

Also supports rounding for aircraft that refuel in 100 Kg/Lb increments when using a 3-tank arrangement.

Once you have calculated your fuel requirements, tap anywhere on the Fuel Chit to see a picture of the aircraft showing fuel distribution in each tank along with total fuel required and total uplift required!

The App is readily updated to reflect the needs of the users. Please email any requests via the in-App feature.

No good if you work on more than 1 type as you can't store multiple aircraft types tank capacities

Very easy to use and very robust. Gives exactly the information needed when needed. Even works out fuel distribution for advance planning in flight. Unlike a calculator, the information remains displayed in case of changes or queries later. Nice one!

Finally an app with the user in mind.

Use it everyday. Less likely to make mistakes with this app and it is also quicker then the old fashioned way. Top app!
