mastershotgun Posted May 7, 2020 Posted May 7, 2020 Hi Guys, Where one can find the formulas that the game is using for fuel consumption, please? The idea is to create a little calculator in excel to help determine how much you need for a mission... Yes! I know that it is complicated! But few things can be averaged, like for example outside temperature is not going to change too much thru the mission and it can spit out more than one value... like for 1000m 2000m 3000m etc...

This page is also your friend for fuel calculation during the flight:
AG-51_Sabot Posted May 7, 2020 Posted May 7, 2020 Do you already know the FPAS page in the DDIs? This page is also your friend for fuel calculation during the flight: Pretty sure the P-51 doesn't have an FPAS page. I know the Tomcat doesn't "There is an art … to flying.

mastershotgun Posted May 7, 2020 Author Posted May 7, 2020 yea I wanted to make something general, like eventualy for all the planes since I going to fly them all...
corn322 Posted May 7, 2020 Posted May 7, 2020 The aircraft manuals should have fuel consumption charted somewhere. I know the Mig-15 and -21 manuals list fuel consumption rates.
mastershotgun Posted May 7, 2020 Author Posted May 7, 2020 well, in that case, not all of them have it, because I was looking in SU-25 and SU-25T and none of them have it... probably true form all FC3 models... This is why I was asking about there it is in the game... I'm hopping for something like in the LUA script to be able to dig it out and read easily
mastershotgun Posted May 10, 2020 Author Posted May 10, 2020 So, no body know where it can be found by any chance, please? Or maybe somebody from ED might be alebo to provide the formula(s), by any chance, please?
BuzzU Posted May 10, 2020 Posted May 10, 2020 Every plane is different and also depends on the pilot, weather, weight of load etc etc. Buzz
ChillNG Posted May 10, 2020 Posted May 10, 2020 I tend to do some test flights to work it out for myself... I will monitor: What is used for startup ---> takeoff What is used in initial climb Then do a 'cruise' speed leg over say 30 miles and work out the fuel burn per mile at a given altitudes. Fuel burn for 5 minute stints of A2A or A2G activity. Fuel for pattern and landing Using that I then built a spreadsheet that when I put in starting fuel and a basic flight profile it spits out the fuel required. Obviously quite crude and a lot of subjectivity in speeds and climb rates and no allowance for drag and weather but works well enough for the A-10. Found it quite hard to find the data I wanted hence measuring it in-game.
BuzzU Posted May 10, 2020 Posted May 10, 2020 The A-10C will fly all day with half-full tanks. It's going to be slow no matter how much fuel it has. I never worry about fuel when flying the Hog. Buzz

Yea I was thinking about it, and it is doable in some aircrafts, like SU-25T where you can see numbers of how much fuel you have, but on for example SU-25 you only see the bar... And some planes go even as far as not showing you the fuel, but instead try to calculate mileage for you with the current parameters...

And some planes go even as far as not showing you the fuel, but instead try to calculate mileage for you with the current parameters... You can monitor fuel through scripting: u0 = Unit.getByName('a') -- Get unit to measure fuel qt0 = u0:getFuel(Unit) -- Get fuel amount as a fraction of 1 (1 = internal fuel only) qt0 = qt0*10000 -- rounding qt0 = math.floor(qt0) -- rounding qt0 = qt0/100 -- rounding to % trigger.action.outText('Unit a: ' ..qt0 .. '%', 10, true) I just estimate range based on experience and test flights. The most important thing to do is to get the right altitude and speed, which can change (altitude in particular) as you burn fuel or release payload. If you want a guide for mission planning, try finding the optimum range up high and then a minimum range under poor conditions like flying low and fast like you might while trying to evade radar. I have an example of a sweep I did for the F-15, focused on finding optimum cruise with 2 tanks, Y is range, X is TAS, colors are altitude: Awaiting: DCS F-15C Win 10 i5-9600KF 4.6 GHz 64 GB RAM RTX2080Ti 11GB -- Win 7 64 i5-6600K 3.6 GHz 32 GB RAM GTX970 4GB -- A-10C, F-5E, Su-27, F-15C, F-14B, F-16C missions in User Files
