At what landing speed can aircraft land on an 800 m long runway when braking with a1 = -2.7
| September 30, 2021 | education
These tasks: S (the length of the landing strip, the path covered by the aircraft) = 800 m; a (aircraft acceleration during deceleration) = -2.7 m / s2.
We express the maximum landing speed at which airplanes can land from the formula: S = -V02 / 2a, whence V0 = √ (-2S * a).
Calculation: V0 = √ (-2 * 800 * (-2.7)) = √4320 = 65.73 m / s.
Answer: Airplanes can land at a landing speed of no more than 65.73 m / s.
