Comments
A parallel course has been selected, causing the vertical deviation to go invalid.
The lateral flight plan contains a procedure turn, vector, or other unsupported leg
type prior to the active vertical waypoint. This prevents vertical guidance to the active
vertical waypoint.
Arriving at waypoint [xxxx], where [xxxx] is the waypoint name.
There is no communication with the #1 transponder.
The #1 transponder should be serviced when possible.
The MFD and PFDs are not communicating with each other. The G1000 system should
be serviced.
