After completing the necessary weight and balance computa-
tions, which will be covered in a later chapter, the manufacturer
provided performance charts must be utilized to properly plan
a safe and efficient flight. It is essential that the pilot be familiar
with the numerous factors that have an effect on airplane per-
formance.

Pressure altitude, when compensated for temperature, will pro-


vide the density altitude. An increase in temperature or pres-
sure altitude will result in a decrease in the density of the air.
Density altitude is the actual altitude that will be affecting the
performance of an airplane.

Surface winds will have an effect on the takeoff and landing


performance. A headwind component can reduce the takeoff
or landing roll required, while a tailwind component will signifi-
cantly increase the required distance.

Most manufacturer provided performance charts for takeoff,


accelerate-stop, and landing distances are based on a paved,
dry, smooth and level surface. Operating an airplane on wet,
grassy, or snow covered surfaces will have an adverse effect
on takeoff and landing performance. In addition, the runway
gradient or slope, will affect the takeoff and landing roll re-
quired.

The Flight Data Performance Card (Page 3) is provided to as-
sist in completing a thorough flight performance plan prior to
flight. Utilizing this form will prepare the pilot for all phases of
the flight from takeoff through climb, cruise, descent, and land-
ing including the possibility of an engine failure.

The performance section of the manufacturer provided Flight
or Information Manual (or information provided with optional
equipment and STC’s) contains the necessary performance
charts required to complete the Flight Data Performance Card.
When using the performance charts follow the guidelines pro-
vided with the chart and always read the conditions and notes
applicable to the chart prior to making any calculations. If inter-
polation of the data is required, always round to the next high-
est, or most conservative number for safety.
