SR22 Performance Data

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). Flap position as
well as power setting technique is similarly noted with each table.
The charts in this section provide data for ambient temperatures from
–20° C (–4° F) to 40° C (104° F). 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
extreme caution as performance degrades rapidly at higher
temperatures.
All fuel flow data for cruise is based on the recommended lean mixture
setting detailed in Section 4 – Normal Procedures.
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 for engine operating limitations.
