(2014) Service Advisory 1449: Unexpected flight path when sequencing to some vectors transition approaches

SYSTEM:
All G1000/G950/G900X/Embraer Prodigy/Cirrus Perspective (with GDU software Version 11.10 and later) and all G2000/G3000/G5000 Integrated Avionics Systems

ISSUE:
Under certain conditions, the FMS may incorrectly calculate, and in some cases display a course from the last waypoint in a flight plan to the final approach course of a procedure loaded with a vectors transition.  This can cause the AFCS, if coupled, to command a turn in the opposite direction from the desired course upon sequencing to the vectors leg of the procedure.

PILOT ACTION:
Always select HDG Mode prior to reaching the end of the final leg of a flight plan prior to an approach
procedure when an approach with a vectors transition is loaded.
