ALTITUDE SELECT DISPLAY
The altitude select display consists of a
white selected altitude digital readout at
the top of the altitude tape and a magenta
selected altitude bug positioned at the
appropriate altitude on the left side of the
tape. The altitude select display has a
resolution of 100 feet.
The magenta altitude select bug moves
along the left side of the altitude tape. The
bug position corresponds to the altitude
select value in the readout. When the
selected altitude exceeds the displayed
range, the bug parks at the top or bottom
of the display with half the bug visible to
indicate the direction of the selected
altitude.
The digital readout is displayed in either
feet or metric units. Metric units are
displayed when metric altitude is
ENABLED from the CONF page. When
altitude is displayed in metric units the
altitude readout is followed by a gray M.
The readout has a resolution of 30
meters.
The selected altitude display is blank on initial power up and
initializes to the current altitude bug location after start up.
If the selected altitude data is invalid, the selected altitude bug is
removed and the selected altitude digital readout is replaced with
amber dashes.
