just wondering as I fly my jets, my dad was a bombardier on a b17 stationed over in England, when I was young he told me when all the bombs were loaded and during take off a lot of times they will hold the brakes at a stand still and let the engines/ propellers rev up until the crew begin to feel the beginning of some shakiness release the brakes and take off with half of the runway, well the runways back then was not that long to begin with. .now that being said in real life can the pilots do that with a passenger plane? I know I do that with my jets and take off at least half of the runway. the 380s its like little over half way.
Hi, in real life life a passenger plane "can" do a maximum performance takeoff as you describe but they normally don't.
All passenger Jets do a calculation of the runway required before each flight taking into account their weight, the winds, the runway conditions etc etc. Then they are required to only take off on a runway that meets that flights minimum requirements. Modern Jets are very powerful and they don't need to run up their power very much before brake release. A max perf takeoff is very scary for passengers due to the engine noise, the shaking and the g-forces pushing them back into their seats after brake release. If you have ever taken off in something like the Learjet on a max perf takeoff you will know what I mean.
In other types of aviation where heavy takeoff weights, short runways, low engine power etc. are involved max perf takeoffs can be common and required to get off the ground. Glad your Dad got through his B-17 Wartime missions OK.
