When FLC is selected on the guidance controller, the FGC selects the
preprogrammed values for a climb or descent. The preprogrammed
value for climb is an airspeed, and for descent, a rate of descent. When
in a climb, the cyan airspeed bug is placed at the pre--programmed
airspeed value. When in a FLC descent,the cyan airspeed bug is
removed, and the vertical speed bug is placed at its preprogrammed
value.
NOTE:
When the flight director is not in the SPD or FLC mode, the
flight director airspeed bug, airspeed target, and target
box on that side remain at the last selected value.
D
Airspeed Trend Vector
-- The airspeed trend vector is positioned
along the outer right side of the airspeed tape. It is referenced to the
airspeed reference line. The magenta vector indicates what the
projected value of indicated airspeed should be in approximately 10
seconds, if the present trend is maintained.
D
Indicated Airspeed (IAS) Analog Scale
-- The airspeed tape is a
moving scale display with fixed pointer and calibrated airspeed
marks. The white scale markings on the tape are in 10--knot
increments. The scale digits move such that larger numbers come
from the top of the display. The scale and its markings are white.

SPEED
Set Bugs
-- In addition to the airspeed bug, V
SPEED
bugs,
corresponding to speeds for various phases of flight, can be displayed
on the PFD’s airspeed tape. This data comes from pilot inputs using
the MFD bezel keys. The V
SPEEDS
travel along the right side of the
airspeed tape. The V
SPEEDS
bug colors are described in table 4--15.
