Description
Correct NAV frequency
is not set in the active
NAV frequency for the
approach procedure.
The selected course
on the CDI/HSI does
not match the current
desired track.
Flight plan contains an
acute course change
ahead which will
require a bank in excess
of normal to follow the
guidance. If coupled
to the autopilot, the
autopilot may not be
able to execute the
steep turn needed
to follow the course
guidance.
The WX-500
Stormscope reports
that it has an invalid
heading source.
The GTN is configured
for a WX-500
Stormscope but is not
receiving data from it.

Action
Insert the correct frequency into
the active navigation frequency

informational only. If desired, slow

GTN Stormscope data is correct
and may be used. Contact dealer
for service.
Close the Stormscope circuit
breaker and ensure Stormscope is
receiving power. Contact dealer for
service.
