Short-Field Takeoff And Maximum Performance Climb

Takeoffs and climbs from fields where the takeoff area
is short or the available takeoff area is restricted by
obstructions require that the pilot operate the airplane
at the limit of its takeoff performance capabilities. To
depart from such an area safely, the pilot must exercise
positive and precise control of airplane attitude and
airspeed so that takeoff and climb performance results
in the shortest ground roll and the steepest angle of
climb. Short-field takeoff

The achieved result should be consistent with the
performance section of the FAA-approved Airplane
Flight Manual and/or Pilot's Operating Handbook
(AFM/POH). In all cases, the power setting, flap
setting, airspeed, and procedures prescribed by the
airplane's manufacturer should be followed.

In order to accomplish a maximum performance takeoff safely, the pilot must have adequate knowledge in
the use and effectiveness of the best angle-of-climb
speed (VX) and the best rate-of-climb speed (VY) for
the specific make and model of airplane being flown.

The speed for VX is that which will result in the
greatest gain in altitude for a given distance over the
ground. It is usually slightly less than VY which provides the greatest gain in altitude per unit of time.
The specific speeds to be used for a given airplane
are stated in the FAA-approved AFM/POH. It should
be emphasized that in some airplanes, a deviation of
5 knots from the recommended speed will result in a
significant reduction in climb performance.
Therefore, precise control of airspeed has an important bearing on the successful execution as well as
the safety of the maneuver.
