The 323-Mg jet airliner has three engines, each of which produces a nearly constant thrust of 231 kN during the takeoff roll.
Determine the length s of runway required if the takeoff speed is 224 km/h. Compute s first for an uphill takeoff direction from A to B
and second for a downhill takeoff from B to A on the slightly inclined runway. Neglect air and rolling resistance.
Assume e = 0.7°.
B
Horizontal
Answers:
Uphill from A to B:
S =
i
m
Downhill from B to A: s =
i
m
