Maximum abort speed is the speed at which the takeoff can be rejected and the aircraft safely stopped on
the runway. Line check speed is the speed an aircraft should achieve in a specified takeoff roll. Given the
following situation at Buckley ANGB, calculate the line check speed after 1,000 ft of takeoff roll, the lift-off
speed, the takeoff distance, and the maximum abort speed:
Takeoff gross wt.
13,000 pounds
Temperature
100 degrees F
Pressure altitude
5,663 ft
Runway length
11,000 ft
Flap

Weather
Overcast clouds, 8 miles visibility
Light rain
No wind
