The unofficial way to land a Gulfstream G280

I get that what he's trying to do is decrease the rate of closure between the main gear and the runway at the last second by rotating the plane.... But isn't that going to be negated by the fact that pitching down increases your rate of descent for the airplane as a whole. The energy of the aircraft sinking has to go somewhere... Traditionally that downward motion is stopped by the flare.

Maybe this works for Eric here, the youngest G-280 pilot in the world according to his bio. I would rather my pilot just follow the checklist set out by experienced company test pilots working with multimillion dollar budgets alongside the engineers who designed the systems.

I think it is also affected by the slight increase in ground effect as the wing flies closer to the runway surface. so the pitching down is somewhat offset by the increase in wing efficiency--and probably a set of other interplaying factors. The G280 has huge barn-door flaps that extend well below the wing, so reducing the distance between these flaps and the runway may result in an appreciable increase in lift (the wing is affected by ground effect if it is <1 wingspan from the ground)
