AIRSPEED INDICATOR
NOTE:
Refer to the current version of the pertinent flight manual for airspeed criteria and Vspeed values.
The Airspeed Indicator displays airspeed on a moving tape rolling number gauge. The numeric labels and
major tick marks on the moving tape are shown at intervals of 10 knots. The minor tick marks on the moving
tape are shown at intervals of 5 knots. Speed indication starts at 20 knots, with 60 knots of airspeed viewable
at any time. The indicated airspeed is displayed inside the black pointer. The pointer remains black until
reaching never exceed speed (V
NE
), then it becomes red. The true airspeed is displayed in knots below the
Airspeed Indicator.

Figure 2-5 Airspeed Indicator
A color-coded (solid red, white, green, amber) speed range strip is located on the moving tape. The colors
denote solid red low speed awareness range, a flaps operating range, normal operating range, caution range,
and never-exceed speed (V
NE
). Speeds above the never-exceed speed (V
NE
), appear in the high speed warning
range, represented on the airspeed tape by red/white “barber pole” coloration.
The Airspeed Trend Vector is a vertical magenta line that appears to the right of the color-coded speed range
strip when airspeed is either accelerating or decelerating. One end of the magenta line is anchored to the
tip of the airspeed pointer while the other end moves continuously up or down corresponding to the rate of
acceleration or deceleration. For any constant rate of acceleration or deceleration, the moving end of the line
shows approximately what the indicated airspeed value will be in six seconds. If the trend vector crosses V
NE
,
the number in the indicated airspeed pointer changes to amber. The trend vector is absent if the speed remains
constant or if any data needed to calculate airspeed is not available due to a system failure.
Black reference bugs with cyan letters appear along the right side of the airspeed scale denote GLIDE, V
R,
V
X
, and V
Y
. The pilot can enable/disable the display of these bugs, as well as change their values. When the
indicated airspeed is below 20 knots, enabled Vspeeds Reference Bugs and their numeric values appear in a list
at the bottom of the airspeed tape, ordered from highest to lowest.
