Question
Takeoff roll (ground roll) is the portion of the takeoff procedure during which the airplane is accelerated from a
standstill to an airspeed that provides sufficient lift for it to become airborne.
An aircraft start from rest and travels a distance of 1.9 km during 29 s with a constant acceleration before
taking off. Analyse the motion of the aircraft and calculate,
• The acceleration:
m/s-2
The speed at the instant the plane takes off after 29 s:
mls
• The distance traveled during the first second:
m
• The distance traveled during the last second on ground (just before takeoff):
m
The speed variation Av [m/s] during the last second on ground:
mls
