This section provides operating limitations, instrument markings and
basic placards required by regulation and necessary for the safe
operation of the SR22 and its standard systems and equipment. Refer
to Section 9 of this handbook for amended operating limitations for
airplanes equipped with optional equipment. Compliance with the
operating limitations in this section and in Section 9 is required by
Federal Aviation Regulations.
Certification Status
The Cirrus SR22 is certificated under the requirements of Federal
Aviation Regulations (FAR) Part 23 as documented by FAA Type
Certificate TC A00009CH.

Airspeed Limitations
The indicated airspeeds in the following table are based upon Section
5 Airspeed Calibrations using the normal static source. When using
the alternate static source, allow for the airspeed calibration variations
between the normal and alternate static sources.
Speed KIAS KCAS Remarks
VNE 201 204 Never Exceed Speed is the speed limit
that may not be exceeded at any time.
VNO 178 180 Maximum Structural Cruising Speed is
the speed that should not be exceeded
except in smooth air, and then only with
caution.
VO
3400 Lb 133 135
Operating Maneuvering Speed is the
maximum speed at which full control
travel may be used. Below this speed the
airplane stalls before limit loads are
reached. Above this speed, full control
movements can damage the airplane.

Maximum Flap Extended Speed is the
highest speed permissible with wing
flaps extended.
VPD 133 135 Maximum Demonstrated Parachute
Deployment Speed is the maximum
speed at which parachute deployment
has been demonstrated.

Airspeed Indicator Markings
The airspeed indicator markings are based upon Section 5 Airspeed
Calibrations using the normal static source. When using the alternate
static source, allow for the airspeed calibration variations between the
normal and alternate static sources.

Remarks
White
Arc
59 - 104 Full Flap Operating Range. Lower limit is the most
adverse stall speed in the landing configuration.
Upper limit is the maximum speed permissible with
flaps extended.
Green
Arc
70 - 178 Normal Operating Range. Lower limit is the
maximum weight stall at most forward C.G. with
flaps retracted. Upper limit is the maximum structural
cruising speed.
Yellow
Arc
178 - 201 Caution Range. Operations must be conducted with
caution and only in smooth air.
Red Line 201 Never exceed speed. Maximum speed for all
operations.
