4. Warnings / Error messages
System failures will be detected by the internal self test function that is performed
continuously.
Failures are detected malfunctions, which can not be eliminated by the user.
Warnings are conditions, which may be followed by a failure. Warnings can be
eliminated by the user under several conditions.
Failures and warnings will be indicated by a visual and audible signal.
4.1. Failure messages
In case of failure, the system shows a
W
on
the LCD screen. Additonally, a frequently
repeated audible signal occurs. Both can be
terminated by pressing the inner knob of
the rotary encoder.
In case of detecting a severe failure, the
system will be switched into Standby (SBY)
mode. All system operating will be
terminated to prevent damages to system
components. In this case, the system
screen will show
FAIL
instead of active
and standby reply code.
General:
In case of failure or warning, an abbreviated
failure
message
will
be
displayed
alternating with the displayed alticode.
Pressing the mode key to select mode on
or alt, the system continues operating until
a new failure is detected.
If a system failure has been detected by the system, always inform the ATC, if
you are flying in a transponder mandatory zone or other airspace, where a
transponder is required. Never try to find the reason for a system failure or
warning during the flight.
