known by initials VTOL which is
vertical take off and landing
example a Harrier jump jet
Aircraft take off and land on airstrips. Airstrips are runways aircraft are planes.
to take off the the aircraft which is operated at a specific speed on the runway
VSTOL = Vertical or Short Take Off and Landing aircraft. Whereas a STOL aircraft is a Short Take Off and Landing Aircraft. Maybe there is a term VTOL just for Vertical Take Off and Landing.
It depends on the aircraft.
The engines provide forward thrust, allowing the wings to generate lift. It is the lift that allows the aircraft to take off.
Most aircraft passenger jets take off at 138 knots
Choppers can hover over a position; fixed wing cannot (other than Harrier type jets). Choppers can land anywhere and take off from anyplace; fixed wing aircraft NEED a large airstrip.
If conditions (airport layout and traffic conditions) allow aircraft take off and land against the wind (headwind). This way the aircraft can take off or approach the runway at a lower ground speed.
like a normal aircraft
true
This varies due to payload (how much weight is on the aircraft) and weather, V1 is normally around 152 KIAS and 164 when the aircraft begins to take off.
This varies depends on the size of the plane. A smaller aircraft like Cessna would need a very less take-off speed than a Boeing. The average take-off speed is 280kmph.
