AIRSPEED INDICATOR
The Airspeed indicator displays airspeed on a rolling
number gauge, using a moving tape. The following infor
-
mation is also displayed:
• Speed indication
• Speed ranges
• Airspeed trend vector
• Vspeed references
Speed Indication
The numeric labels and major tick marks on the mov
-
ing tape are marked at intervals of 10 knots, while minor
tick marks on the moving tape are indicated at intervals
of 5 knots. Speed indication starts at 20 knots, with 60
knots of airspeed viewable at any time. The actual air
-
speed is displayed inside the black pointer. The pointer
remains black until reaching never-exceed speed (V
NE
), at
which point it turns red.
Speed Ranges
A color-coded (white, green, yellow, and red) speed
range strip is located on the moving tape. The colors de
-
note flaps operating range, normal operating range, cau
-
tion range, and never-exceed speed (V
NE
). A red range is
also present for low speed awareness. Refer to the Pilot’s
Operating Handbook (POH) for speed criteria.
Airspeed Trend Vector
The vertical, magenta line extends up or down on the
airspeed scale located right of the color-coded speed range
strip. The end of the trend vector displays approximately
what the airspeed will be in 6 seconds if the current rate
of acceleration or deceleration is maintained. The trend
vector is absent if the speed remains constant and if any
data needed to calculate airspeed is not available due to a
system failure.
Vspeed References
Vspeeds are set using the TMR/REF softkey. Glide, V
R
,
V
X
, and V
Y
are shown on the References window. When
active (ON), the Vspeeds are displayed at their respective
locations to the right of the airspeed scale (refer to the
Auxiliary Windows portion of this PFD section to set and
display Vspeeds).
True Airspeed Box
The True Airspeed box is located below the Airspeed
indicator and displays the true airspeed in knots.
