It should hover ok.
since its skids are in contact initialy with the a/c going at 440kts... (
-i know ur example is different but this should get a firm understanding on the forces at work.)
...it is given that boost of horizontal velocity, therefore must hover ok as it is also traveling at 440kts realative to the ground, but 0kts realative to the a/c.
thats the way we're taught in the world of physics anyway.
and if you think about it, the earth is spinning at thousands of miles per hour.. now correct me if im wrong, but that is similar to the situation we are discussing? It proves that since we are on the earth, we too are spinning at those thousands of miles per hour, thus when the wheels leave the ground we are given that invisible boost of horizontal velocity, realative to the ground yes we are moving at 400kts, but relative to the universe as a whole we are going at say <>1000400kts?< (a random number i have no idea of the actual speed we are turning)
what im saying is basicaly a huge version of-
when u drop a feather in your car, it does not shoot to the back, simply falls normally, since your hand has transferred horizontal velocity thus it keeps up with the car.
in a hover the helicopter doesnt fall downwards so this kinetic energy in the horizontal velocity would soon bleed of so it would eventually end up at the back of the a/c
however everything i have just said requires a bit of though and i hope iv put it across clearly
