Balu Posted May 4, 2015 Posted May 4, 2015 While integrating the Mig-21 into my Flight Planning Tool I have noticed a difference between the manual and the values displayed in the mission editor. Small external tank Manual (page 15): 382kg fuel + 52kg tank weight= 434kg Mission Editor: 436kg Difference: 2kg Big centerline tank: Manual (page 15): 625kg fuel + 57kg tank weight = 682kg Mission Editor: 689kg Difference: 7kg My question is, is this a mistake of the manual or is the mission editor displaying a wrong value for the tanks or is the difference the weight of the rack of the tank?
Aginor Posted May 4, 2015 Posted May 4, 2015 Maybe just a rounding error. IIRC the mission editor uses lbs internally. DCSW weapons cheat sheet speed cheat sheet
Bestandskraft Posted May 4, 2015 Posted May 4, 2015 I cannot answer your question directly, but I've faced the exact same problem when building my own Excel-based loadout/ops limits spreadsheet. Through some testing and logical deduction, I have found the following values are consistent with the numbers in the mission editor: A 490-l tank holds 388 kg of fuel, and an empty 490-l tank (including the rack) weighs 48 kg. A 800-l tank holds 639 kg of fuel, and an empty 800-l tank (including the rack) weighs 50 kg. See also http://forums.eagle.ru/showthread.php?t=139374 for some of the related efflux of my testing.
