I´m asking the mod for this forum to split this when time available as it is definitely going ´thread creepy´
landing config. body angle at a normal landing weight: -0.3 degrees, i.e. slightly nose down.
FW - are we getting attitudes confused here - is that the ´landing attitude´or the ´approach attitude´? If the former, I would expect loads of nosewheel first touchdowns? I would venture to suggest that most a/c land in a nose high attitude - also what is the engine mounting angle?
My MAIN point is to try to discourage last minute ´grabs´such as you describe. Having sat through endless ´circuits and BUMPS´in aircraft from 152 through Jet Provost to just ´BUMPS´ in Lightnings and 737s, I can assure you that such ´grabs´are not helpful in all but the first two types. That is most definitely NOT an OWT.
If you have any doubts about the ´physics´ of rotational kinetic energy, take one of your most expensive and fragile wedding dinner plates, rest it on a suitable pivot (NB Zero descent rate), and then whack one side of it downwards onto a concrete floor.
