A helicopter should be a be able to hover as long as it has fuel to. And the current atmospheric conditions and pilot fatigue levels permit.
It hovers as long as the fuel tank lasts.
Indeffinently within fuel limitations, or system temperatures.
The Helicopter with the long propellers creates more list and has to do less rotations, and use less power than the one with short proplellers. Therefore Helicopter with the long propellers will hover and stay in air longer than the one with short propellers.
Jump close to it and use air kick followed by grab. You can also use whipfist to hijack it after you've purchased the "long shot grab" ability; just equip whipfist and press grab when you're close enough to the helicopter.
No, a helicopter will not drop from the sky if it hovers in one spot for too long. Helicopters are designed to hover, and their engines provide continuous lift to keep them airborne. However, factors like fuel consumption and engine performance should be monitored to ensure safe operation.

So they can get the ball of the ground on holes that are long. On some courses you don't need them because they are so close. So they can get the ball of the ground on holes that are long. On some courses you don't need them because they are so close.
No. The submarine came about long before the helicopter.
Depends on flight conditions, elevation, loads, if the engine is running and warmed up etc. but usually it's a matter of seconds.
I doubt that any helicopter can fly from Antarctica to Australia.
The Grand canyon is a Big Long hole in the ground. So no But you can fly through the Grand Canyon. Many airplane and helicopter tours every day.
