I know this is not as serious of a topic as you are all used to, but hopefully someone could help me out anyways? - Imagine a helicopter hovering inside a cargo jet, (the jet is flying at cruising speed). What would happen to the helicopter if it was pushed outside the jet, with no changes being made to the controls. So if the main rotor keeps spinning at a constant speed... when the helicopter leaves the plane does it keep or lose altitude? - Imagine a helicopter hovering in a elevator. If the controls in the helicopter are not touched, what happens when the elevator moves? - If a helicopter is flying just feet off the ground, and the ground suddenly drops off (like a cliff), does the helicopter require more thrust to keep the same altitude? any input would be appreciated!
