Using the Take-off Performance Table, what is the ground roll distance required for take-off?
Pressure altitude = 500 ft
Weight = 2400 lbs
Outside air temperature = +10°C
Refer to figure.
The conditions given are 500 ft pressure altitude and +10°C, which falls exactly halfway between Sea Level and 1000 ft.
At +10°C, the ground roll at Sea Level is 845 ft and the ground roll at 1000 ft is 925 ft.
Linear interpolation at the midpoint (500 ft) gives: 845 + (925 - 845) × 0.5 = 845 + 40 = 885 ft.
No wind correction is needed since the table baseline is zero wind, and no grass correction applies as the question specifies no surface type modification.
The correct answer is therefore 885 ft.
