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 200 200 Never Exceed Speed is the speed limit
that may not be exceeded at any time.
VNO 165 165 Maximum Structural Cruising Speed is
the speed that should not be exceeded
except in smooth air, and then only with
caution.

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.
