What is an airplane take off speed?

Answer 1

varies greatly, depends on a lot of factors such as: air preasure, temperature, humidity, wind speed and direction, amount of fuel, cargo and passengers, angle of attack (angle of wings to air flow), use of flaps, drag (shape and size of the aircraft causes air resistance), condition of aircraft such as dents and abrasions and ice or other accumulation on the wings every aircraft has its own takeoff speeds that are found through test flights but are subject to change as the aircraft ages such as dents and other damage to the outer skin of the plane also aircraft speeds are not the same as a car which are ground speeds - aircraft speeds are calculated by its speed in relation to the air, not the ground - so its ground speed varies by the direction and speed of the wind - planes usually take off into the wind so its ground speed at takoff is its airspeed minus the wind speed so if a planes takeoff airspeed is 60 mph and the wind is 30 mph its ground speed is 30 takeoff speeds vary from small aircraft with high lift wings at about 30 mph to supersonic craft with small wings at around 200+ mph - aircraft speeds are usually stated in knots where 1 knot equals about 1.15 mph
