Airspeed Indicator Markings

Airspeed Indicator Markings

V speeds are nearly always given as Indicated Airspeed (IAS), so that pilots can read them directly off the airspeed indicator (ASI). ASIs carry color–coded markings that give the pilot an immediate reference, as follows. New Winter ASI's can be purchased with optional factory installed markings. You can retrofit your Winter ASI with a color marking kit as well.

VNE Red line and top of yellow arc. The VNE, or the never exceed speed, of an aircraft is the V speed which
refers to the velocity that should never be exceeded due to risk of structural failure, most commonly due
to wing or tail deformation or failure and less commonly due to aeroelastic flutter (usually in faster aircraft).
VNE is specified as a red line on many airspeed indicator. This speed is specific to the aircraft model, and
represents the edge of its performance envelope.
VA Top of green and bottom of yellow arcs. The yellow arc is caution, as speeds in this region may
add dangerous stress to the aircraft, and are only to be used in smooth air when no turbulence or
abrupt control inputs are expected. Design maneuvering speed (stalling speed at the maximum legal G force,
and hence the maximum speed at which abrupt, full deflection, control inputs will not cause the aircraft
to exceed its G–force limit). Maneuvering speed is limited by aircraft structural characteristics. With
the Cirrus SR20 and SR22, this speed is also known as V0.
VFE Top of white arc. Maximum flap extended speed (a different maximum speed may be specified for partial flap extension).
VX Best angle of climb speed. (In sailplanes this yellow triangle typically marks pattern speed in calm conditions)
VS1 Bottom of green arc. The stalling speed or the maximum steady flight speed obtained in a specific configuration
(usually a configuration "clean" of flaps, landing gear and other sources of drag).
VS0 Bottom of white arc. Stall speed in landing configuration.
