the AOA display. To judge when a stall will occur, remember that the AOA indicator is showing actual AOA, and the
stall AOA changes with configuration. Because of this, a stall could occur anywhere inside the yellow range, but will
occur at the same point every time given a specific configuration. Refer to the FlightDEK-D180 Installation Guide for
more information on calibrating the AOA indicator.
Airspeed tape, digital readout, and trend
The airspeed tape scrolls beneath the airspeed digital readout and arrow. The digital readout’s digits scroll up
and down, simulating an analog airspeed indicator and giving a sense of the increase or decrease in speed. The
FlightDEK-D180 is factory-calibrated to be accurate for airspeeds between 15 and 325 knots (17 to 374 mph).
As airspeed increases from 0 knots, the indicator becomes active at 20 knots. The indicator remains active until
airspeed drops below 15 knots. The FlightDEK-D180 may display airspeeds above 325 knots, but it is not
guaranteed to be accurate.
The airspeed tape utilizes 4 colors to give you a graphical representation of your speed with relation to your
aircraft’s limits. By default all of the color thresholds are set at 0, causing a grey tape to be displayed. You
must set the values of the airspeed color thresholds via the SETUP menu. Refer to the FlightDEK-D180
Installation Guide for more information on setting the airspeed color thresholds.
The airspeed trend indicator is located to the left of the airspeed tape. The magenta bar grows in the direction of—and in
proportion to—the rate of acceleration or deceleration. The trend indicator is scaled to indicate a 6-second airspeed trend.
In the example at right, the trend indicator is showing that the aircraft will reach 124 knots in 6 seconds if the rate of
acceleration does not change.
Bugs
Bugs may be set to mark a desired heading, airspeed, or altitude. These bugs are represented by a yellow
inverted arrow located at the desired value on the tape. If the set heading, altitude, or airspeed is
currently off-screen, the bug icon appears at the edge of the moving tape closest to the desired value.
