Service Advisory 1514 Rev B: Potential Erroneous Lateral Guidance


All G900X, G950, G1000, Embraer ProdigyTM, and Cirrus PerspectiveTM systems with GDU Software v13.01 or later, and all G2000, G3000, G5000, and Embraer Prodigy Touch systems with GDU Software v2.01 or later are affected.


Flight management system may provide erroneous lateral guidance when navigating certain legs of a terminal procedure, including SID, STAR, instrument approach, and missed approach procedures.  The final approach segment from the FAF to MAP is not affected.


Removing/deleting the active flight plan and creating a new flight plan within the same power cycle will not clear the condition.


Monitor the Navigation Map page on the MFD when flying terminal procedures and always compare displayed flight path depictions with applicable published procedures.  If this condition occurs, follow CDI course guidance manually and/or by using AFCS Heading Mode.
