Depends how big a helicopter.
No, a helicopter cannot take off from the moon because there is no atmosphere on the moon to generate lift for the helicopter's rotor blades. Helicopters require air to push down against to lift off the ground, and since the moon has no atmosphere, a helicopter would not be able to take off.
Because all they need is their main rudder to spin fast enough to get the helicopter off the ground. They need only enough room to spin the rudder and for the helicopter to fit in a space. They don't need to go forward fast to lift off, unlike planes and shuttles.
There is no need to. I would not take into the paint shop with a tank full off fuel
No, a helicopter cannot take off from the moon because there is no atmosphere to generate lift for the rotor blades to work. Helicopters rely on air density to generate lift, and the lack of atmosphere on the moon makes it impossible for a helicopter to fly.
time for an helicopter to takeoff varies on types and model of the helicopter it self. this is because every helicopter or aircraft have their own check list provided by the manufacturer or operator depending on operation. this check list is for the pilot to go through during start up, taxing, take off, approaching and landings. again, time for each machine to take off varies.
Just keep driving around and the helicopter should back off after a while
So aircraft could land and take off in confined spaces and off small ships.
Mainly the problem of landing and take-off in small spaces
Take the paper clip off and make it smaller.
While airplanes need to be in motion with enough momentum to create enough airspeed for lift off, helicopters can lift off vertically without any momentum of the aircraft. Both aircrafts need a rotary wing. Helicopter wings are rotary and have the capabilities to change the angle or pitch in order to create more or less lift. Airplanes have rotary and fixed wings.
Pushing Air downwards to fly. Rapidly spinning long, thin blades push air downwards to lift the helicopter up
