INTRODUCTION
The performance graphs in this section were prepared by Piper Aircraft in accordance with FAA
regulations. Test data is corrected to ICAO Standard Day conditions. The information shown is
unfactored and does not make any allowance for variations in pilot proficiency andfor mechanical
condition of the aircraft.
Effects of conditions not considered in the charts such as a grass runway surface on takeoff and
landing performance, or the effect of winds aloft on cruise and range performance must be
evaluated by the pilot. Range and endurance can be greatly affected by improper leaning. In-flight
he1 flow and quantity checks are therefore recommended.
FLIGHT PLANNING EXAMPLE
The following sample flight problem utilizes information derived from the various charts in this
section to determine the predicted performance data for a typical flight. Many of the charts
contain an example to show how they are used.
Performance information is not valid if readings
from the charts are obtained by extrapolation
beyond the limits shown on the charts.
1.) Aircraft Loading:
Airplane gross weight and center of gravity may be determined by utilizing information
provided in Section
6 (Weight and Balance) of this Manual. The following has been provided
for the purpose of computing this flight planning example.
Takeoff Weigh
Center of Grav
Usable Fuel
........................ .. ..................................................................... 56 GaU336 lbs
Takeoff Conditions:
Temperature
...................................................................... 70 Degrees F. (21 Degrees C.)
Pressure Altitude
...................... .................. ....................................................... 2000 ft MSL
Runway Length Available .......................................................................................... 4100 ft
Runway Headwind Component ................................................................................. 10 kt
When consulting the Takeoff Performance chart it is necessary to keep in mind that the
distances shown are based on use of the short field technique. Ground run distance can be
expected to be approximately twice the distance shown when making a standard takeoff
............................. ...................................................... Ground Run (Figure 5-01) .... 960 fi
Total Distance to Clear a 50 R Obstacle (Figure 5-08) ............................................. 1510 ft
Minimum Safe Runway Length Required for Aborted Takeoff ................................... 3000 ft
