Question

При какой скорости самолет отрывается от земли?

Answer 1

Скорость взлета за железкой самолётов :
Як 40 -180 км/ч . Ту 154М -210км/ч
Boeing 737-220

220км/ч

Answer 2

Самолет оторвется от земли только в тот момент, когда скорость движения по взлетно-посадочной полосе достигнет значения 220 км/ч.

Answer 3

The speed at which an airplane takes off and becomes airborne varies depending on several factors, such as the aircraft's type, weight, and weather conditions. Different aircraft have different takeoff speeds, and these speeds are specified by the manufacturer and are typically called V-speeds.

The critical takeoff speed for most airplanes is the "takeoff speed" or "rotate speed," denoted as Vr. This is the speed at which the pilot rotates the aircraft's nose up to lift off from the ground. The airplane must reach or exceed Vr to safely take off.

For larger commercial jet airliners, Vr speeds can range from around 120 to 180 knots (138 to 207 miles per hour or 222 to 333 kilometers per hour). Smaller general aviation planes, like light aircraft or small business jets, might have Vr speeds between 60 to 100 knots (69 to 115 miles per hour or 111 to 185 kilometers per hour).

Remember that the specific Vr speed will differ depending on the aircraft model and the specific conditions of the takeoff, so it is essential for pilots to consult the aircraft's operating manual or the performance charts for precise takeoff speeds.
