Introduction

Performance data in this section are presented for operational
planning so that you will know what performance to expect from the
airplane under various ambient and field conditions. Performance data
are presented for takeoff, climb, and cruise (including range &
endurance).

Associated Conditions Affecting Performance

Computed performance data in this section are based upon data
derived from actual flight testing with the airplane and engine in good
condition and using average piloting techniques. Unless specifically
noted in the "Conditions" notes presented with each table, ambient
conditions are for a standard day (refer to Section 1,
Terminology). Flap position as well as power setting technique is
similarly noted with each table.
The charts in this section provide data over temperature ranges as
specified on the chart. If ambient temperature is below the chart value,
use the lowest temperature shown to compute performance. This will
result in more conservative performance calculations. If ambient
temperature is above the chart value, use caution as performance
degrades rapidly at higher temperatures.
Aircraft with optional Air Conditioning System: Brake Horsepower is
reduced by approximately 6 BHP.

Demonstrated Operating Temperature

Satisfactory engine cooling has been demonstrated for this airplane
with an outside air temperature 23°C above standard. The value given
is not considered an operating limitation. Reference should be made
to Section 2, Powerplant Limitations
P/N 21399-004 P/N 21399-004
