Flight Director VS Target Display and Bug
-- Engaging the
vertical speed mode brings the VS target bug into view. The VS
target bug moves along the right side of the VS scale. The bug lines
up with the value on the VS scale that is set with the guidance
controller. The bug is always cyan. The digital readout of the target
is displayed on top of this vertical speed scale. The target comes
from the flight guidance system.
NOTE:
When the flight level change (FLC) FD mode is used in a
descent, the vertical speed bug and target display are
positioned at the preprogrammed rate of descent value.
