picture. Thousands of feet are displayed using large numbers while hundreds of feet are displayed in small numbers. As
mentioned above, the altitude tape will not be displayed during the first 30 seconds of operation.
Angle of attack (AOA) tape
The angle-of-attack tape indicates the aircraft’s current AOA relative to the stall AOA. The AOA calibration
process, described in the AOA/Pitot Installation Guide, will nominally result in the lowest angle-of-attack
stall (usually the “clean” configuration) occurring at the intersection of the yellow and red lines and the
higher angle-of-attack stall (usually the “dirty” configuration) occurring at the top of the red. To properly use
the AOA indicator, the pilot must keep in mind the present configuration of the aircraft and the corresponding stall
indication on the AOA tape. Please refer to the AOA/Pitot Installation Guide for more information.
Airspeed digital readout
In the upper left region of the display, you will find the digital readout of your current airspeed.
Like the altitude digital display, its numbers are the largest characters on the screen, giving you
quick access to important information as you scan the display.
Airspeed tape
The airspeed tape utilizes 4 colors to give you a graphical representation of your speed. By default
all of the color thresholds are set at 0, displaying a grey tape. You must utilize the EFIS-D10
Support Program on your PC to set the values of the airspeed color thresholds. Please see the Help
File for the EFIS-D10 Support Program for more information.
