Accelerate-Go The distance to accelerate to Rotation Speed, experience an engine failure, continue accelerating to lift¬off, then climb and accelerate in order to achieve 35 ft speed at 35 feet above the runway.
Accelerate-Stop  The distance to accelerate to Decision Speed and stop.
AGL Above Ground Level.
Best Angle-of-Climb The Best Angle-of-Climb delivers the greatest gain of altitude in the shortest possible horizontal distance with gear and flaps up.
Best Rate-of-Climb The Best Rate-of-Climb delivers the greatest gain of altitude in the shortest possible time with gear and flaps up.
Clearway A Clearway is an area beyond the airport runway not less
than 500 feet (152.4 meters) wide, centrally located about the extended centerline of the runway, and under the control of the airport authorities. The Clearway is expressed in terms of a clear plane, extending from the end of the runway with an upward slope not exceeding 1.25 percent, above which no object nor any terrain protrudes. However, threshold lights may protrude above the plane if their height above the end of the runway is 26 inches (66 centimeters) or less, and if they are located to each side of the runway.
Climb Gradient  The ratio of change in height during a portion of a climb, to the horizontal distance traversed in the same time interval.
Demonstrated Crosswind The demonstrated crosswind component for which adequate control of the airplane during takeoff and landing was actually demonstrated during certification tests. The value shown is not limiting.
