Formula to calculate how much range your craft has. (In terms of minutes)

17.4k RYMA232Aeronautics  6.1 years ago

T=Time it takes for your fuel level to go down by 1%. (In Seconds)
P=Percentage of fuel left in your tank. (Keep as percentage, do not turn to decimal. EX: Keep as 80% in the formula, not .8)
R=Range in minutes.

I made this when trying to compare ranges between my executive aircrafts.

    O, sounds cool@camero2000

    @RYMA232Aeronautics I once experienced with that, as well as an analog gauge for it. The label had different results, maybe because of me using different variables for Funky Trees. But I'll try again.

    Nice. Now that SP is more friendly to code, it would be cool if you made a label that displayed that calculation in real time. IF you make it lmk and I will use it on something.@camero2000

    I have a slightly better idea, but it calculates how much potential range is left, therefore it might not give the actual range of the vehicle:

    You take (average) speed , the (average) time it takes for fuel to decrease by %1 in seconds, multiply it with 100, then divide it by 3600 (to convert it to hours), then multiply the result with speed.

    E.g. average speed is 300km/h and it takes 60 seconds for a %1 decrease in fuel. It would be 6000 seconds, which would meant 1.667 hours, which would give an average range of 500 kilometres.

    Alright then, welp even if it does, the formula still gives a pretty good rough estimate.@WNP78

    @RYMA232Aeronautics pretty sure SP does adjust the mass based on remaining fuel.

    but if it was an underestimated time then you would have extra fuel for a landing after that he could time ran out @WNP78

    I see your point, but I dont believe simple planes logic takes that into account. This formula is meant for only simple planes.@WNP78

    But, when there is less fuel left in the aircraft, it is lighter, and can therefore fly faster using the same amount of fuel, so is more efficient. Therefore, this equation would produce an underestimate of the range.

    Its made for simple planes scaling :P@jamesPLANESii

    Well, yes.
    Endurence of my Moray with a realistic amount of fuel be like 5 minutes lol

    I see what you mean, but it still gives you the amount of minutes you have left, taking into account the endurance at different altitudes that you record it at.@RAF1

    This is a formula for endurance, not range.

    My formula was originally multiplying by 100, but then I decided to make it a variable so people could see what there range was on any percentage. (Hence the “The given range is from 100% of fuel”)@randomusername

    Welp, this works too, so enjoy if you want :P @randomusername
