SHORT FIELD -
Set the Reference Marker adjacent to
the second
green
LED above the center ON-SPEED
position. Fly the aircraft at the AFM/POH listed
airspeed for a Short Field Landing Approach. Note the
corresponding Indexer Computer indication.
The SCc AoA Sys
tem incorporates an LAA function.
When the airplane reaches the near maximum lift
coefficient, the Indexer Computer will display two
flashing
red
LEDs and an increasing frequency of
“Geiger”-counter-like audio (wired into the aircraft audio
panel and/or pilot headset). The audio will start when the
two
amber
LEDs are illuminated at a low frequency and
will increase in frequency as the AoA increases.

* Holding for 2 seconds, dims or brightens the display.
* This function is only available with s/n 167304-01 and above and software version 1.3.0 marked on the indexer
