The plane for take-off must acquire a speed of 369 km / h. if the acceleration time of the aircraft is about 25 s, then the length of the runway should be …
To determine the required length of the runway under consideration, we apply the formula: S = (V + V0) * t / 2.
Variables: V – take-off speed (V = 369 km / h; in SI V = 102.5 m / s); V0 – speed before acceleration (V0 = 0 m / s); t – acceleration duration (t = 25 s).
Let’s calculate: S = (V + V0) * t / 2 = (102.5 + 0) * 25/2 = 1281.25 m.
Answer: The length of the runway must be at least 1281.25 m.
