DISPLAYED ALERT MESSAGES
The following table describes the alert messages that the EFIS-D60 can display.
Alert Message Description End condition
INTERNAL ERROR
SERVICE UNIT
This error can occur for a few reasons, including
an aborted upload. It signifies that the EFIS-D60
has detected internal problems in its firmware or
calibration tables.
When this error appears, it may be possible to
recover your unit in the field. The best way of
ensuring this is to call Dynon Avionics
immediately. However, there is a good
possibility that the unit will have to be returned
for service.
ATTITUDE
RECOVERING…
This alert is displayed anytime the unit is rotated
at a rate faster than 150 degrees/second or the unit
is powered on with airspeed applied. Rotating the
unit faster than this threshold will saturate the
gyros, leading to potentially erroneous display.
The blue/brown horizon indication will turn grey
and black to indicate that the artificial horizon is
not currently a trusted source. Note that this alert
only appears when airspeed is non-zero; using the
EFIS-D60 on the bench will not trigger this alert.
The grey/black horizon indication and onscreen
message will remain until the unit has resumed
normal operation. In the case of rotation rate
greater than 150 degrees/second, the unit enters
a fast recovery mode and usually recovers
within 5 seconds of coordinated flight.
