− Color:
− V
1
: magenta

: White
− AP: green
− Presented when the associated digital indication is selected or
above 40 KIAS on the ground.
− Removed above V
2
+ 42 kt.
− May be out of view, if airspeed is reduced below 230 KIAS
followed by an increase above 230 KIAS. To display the speeds
again, press the reference speed buttons.
− When the airplane speed is below 40 knots, V
1
, V
R
, and V

, as
set on the MFD, are displayed in the bottom portion of the
airspeed tape in the form of a digital indication. Upon power up,
the digital indications for the set bugs are dashes.

to higher airspeeds.
− Ranges from 0.05 to 1.000 M with a resolution of 0.001 M.
− Mach number and label are displayed when speed exceeds
0.45 M and remains until it drops below 0.05 M.
6 - LOW AIRSPEED AWARENESS
− Displayed in the airspeed scale when the airspeed is near stall
speed for the current configuration.
− Colors:
− White: indicates the speed range from 1.23 V

.
− Amber: indicates the speed range from 1.13 V
S
to V
