Definition
The minimum distance an airplane travels along the runway from the start of the takeoff roll to the point of liftoff, achieved by using the specific short-field takeoff technique and airspeeds published in the Pilot's Operating Handbook for the existing weight, configuration, and conditions.
Plain English
The least amount of runway used before the wheels leave the ground, achieved by flying the airplane exactly the way the manual says to for a short-field takeoff.
Context Anchor
Used in short-field takeoff training, especially when the runway is short or there are obstacles near the departure end.
Why Pilots Care
Determines whether a short or obstructed runway is usable for takeoff, directly affecting safety margins.
Grounding Statement
Picture the airplane starting from a stop on a short runway; the shortest ground roll is the shortest stretch of pavement it uses before the wheels leave the ground.
Intuition Check
Do not confuse shortest ground roll with shortest total takeoff distance. Ground roll ends when the wheels leave the runway; total takeoff distance may include the distance needed to climb safely after liftoff.
Example Sentence 1
To get the shortest ground roll, the pilot used full flaps as recommended, held the brakes while applying full power, and rotated at the speed published in the POH.
Example Sentence 2
Proper technique during the short-field takeoff produced the shortest ground roll possible under the existing conditions.
