may also occur when near or in the stall. This audio alarm is accompanied by a flashing red triangle at the top of 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 EFIS-D60 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
EFIS-D60 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 EFIS-D60 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 EFIS-D60 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 acceleration
does not cha nge .
