An F/A-18 taking off from an aircraft carrier An Embraer E175 taking off. Takeoff is the phase of flight in which an aerospace vehicle leaves the ground and becomes airborne. For aircraft traveling vertically, this is known as liftoff.
Short Take-Off and Vertical Landing or Conventional Take-off and Landing operation is preferred to VTOL operation. V/STOL was developed to allow fast jets to be operated from clearings in forests, from very short runways, and from small aircraft carriers that would previously only have been able to carry helicopters .
Steady initial climb speed. The all engines operating take-off climb speed used to the point where acceleration to flap retraction speed is initiated. Should be attained by a gross height of 400 ft (120 m). [10] V A: Design maneuvering speed. This is the speed above which it is unwise to make full application of any single flight control (or ...
When taxiing, aircraft travel slowly. This ensures that they can be stopped quickly and do not risk wheel damage on larger aircraft if they accidentally turn off the paved surface. Taxi speeds are typically 16 to 19 kn (30 to 35 km/h; 18 to 22 mph). [8] Rotor downwash limits helicopter hover-taxiing near parked light aircraft.
The maximum take-off weight (MTOW) was set at 220,000 pounds (99,800 kg), [16] which was 10,000 pounds (4,540 kg) more than the 727. [17] The 757's higher thrust-to-weight ratio allowed it to take off from short runways and serve airports in hot and high conditions with higher ambient temperatures and thinner air, offering better takeoff ...
So if an aircraft's wing area is increased by 10% and nothing else is changed, the takeoff speed will fall by about 5%. Likewise, if an aircraft designed to take off at 150 mph grows in weight during development by 40%, its takeoff speed increases to ≈ 177 mph.
It does not list helicopters or vertical take-off and landing aircraft. Fixed-wing aircraft are limited by their stall speed, the slowest airspeed at which they can maintain level flight. This depends on weight, however an aircraft will typically have a published stall speed at maximum takeoff weight.
Instead of a catapult, they use a ski jump to assist aircraft in taking off with a positive rate of climb. Carrier aircraft such as the J-15, Mig-29K, and Su-33 rely on their own engines to accelerate to flight speed. As a result, they must take off with a reduced load of fuel and armaments.
