No. Not only NO but FRACKLE NO.
'lemme guess... this wish is to give that wee extra but of turn radius that is thought to make you superior in the virtual skies of AH? Being able to make your plane as light as possible it whips around like in the movie "Redtails"? This must be similar to those bananas that dump the rear gun ammo in the 110 and 410 thinking it gives them an "advantage" of some sort.
Of the countless ferry runs and missions and "mail runs" my grandfather did in aircraft such as the B24D, B17F, C47, C45F, C87A, L48, UC61A, and a host of others, there are just a few flights that he lifted without 100% fuel. He lifted in B17F's from somewhere in AZ and flew them to San Fran with less than 100%, how much is actually unknown because the logs only say "ferry load" in the fuel column. Everything else was 100%. Mind you that most of his flights were over the south PTO and fuel was more important than bomb load.
Point being, fuel is a huge part in flight and being able to manipulate such things to that degree is a bit much. In the real deal the importance of fuel and range were more important than in AH, and that is sad. The "fuel dump" wish is another
moment for me. AH already has too many ways to "game the game", I think it is a shame we can take 25% and DT. That right there should be your "wish granted".
