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.

Flight Planning
The performance tables in this section present sufficient information to
predict airplane performance with reasonable accuracy. However,
variations in fuel metering, mixture leaning technique, engine &
propeller condition, air turbulence, and other variables encountered
during a particular flight may account for variations of 10% or more in
range and endurance. Therefore, utilize all available information to
estimate the fuel required for a particular flight. Additionally, verify that
the weather, field length, wind, anticipated turbulence, and other
conditions that affect aircraft performance are judged to be satisfactory
and conducive to safe operations and compliant with the Federal
Aviation Regulations (FARs) or governing regulations, as applicable.
• Note •
Whenever possible, select the most conservative values from
the following charts to provide an extra margin of safety and to
account for events that could occur during a flight.
Sample Problem
The following sample flight problem uses information derived from the
airplane performance charts and tables to determine the predicted
performance for a typical flight.
The first step in flight planning is to determine the aircraft weight and
center of gravity, as well as information about the flight. For this
sample problem, the following information is known:
Airplane Configuration:
• Takeoff weight........................................................3400 Pounds
• Usable fuel.................................................................81 Gallons
Takeoff Conditions:
• Field pressure altitude ................................................1750 Feet
• Temperature ................................................25° C (ISA + 13° C)
• Wind component along runway ......................11 knot headwind
• Runway Condition ............................................Dry, level, paved
• Field length .................................................................3000 Feet

Takeoff
The takeoff distance tables, Figure 5-9, show the takeoff ground roll
and horizontal distance to reach 50 feet above ground level. The
distances shown are based on the short field technique.
Conservative distances can be established by reading the tables at the
