Cirrus Design Section 9
SR22 / SR22T Supplements
• Accumulation of ice on the upper surface or lower surface of the
wing aft of the protected area.
• Accumulation of ice on the propeller spinner farther back than
normally observed.
If the airplane encounters conditions that are determined to contain
freezing rain, freezing drizzle, or severe icing, immediately exit
condition by changing altitude, turning back, or if clear air is known to
be immediately ahead, continue on course. Once clear of these
weather conditions, report encountered weather to air traffic control
• Note •
The National Weather Service's Automated Surface
Observing Systems (ASOS) program does not report freezing
drizzle. It is the pilot's responsibility to evaluate and
understand weather along the intended route and identify any
potential weather hazards thru evaluation of, but not limited to,
Current Observations, Pilot Reports, Area Forecasts,
AIRMETS, SIGMETS, and NOTAMS.
Airspeed Limitations
Minimum airspeed for flight into known icing conditions......... 95 KIAS*
*Includes all phases of flight, including approach, except as required for takeoff and
landing.
Max airspeed Anti-Ice System operation........177 KIAS and 204 KTAS
Recommended holding airspeed............................................120 KIAS
Weight Limits
Maximum weight for flight into known icing conditions .............. 3400 lb
Takeoff Limits
Takeoff is prohibited with any ice, snow, frost or slush adhering to the
wing, stabilizers, control surfaces, propeller blades, or engine inlet.
Performance Limits
Refer to Section 5 - Performance for limitations that reflect effects on
lift, drag, thrust and operating speeds related to operating in icing
conditions.
