Abnormal Operating Procedures - Garmin GNS 530 Manual

Supplement A21
DA 40 AFM
GNS 530
AUTOPILOT COUPLED OPERATION
Coupling of the GNS 530 System steering information to the autopilot can be
accomplished by engaging the autopilot in the NAV or APR mode. When the autopilot
system is using course information supplied by the GNS 530 System, the course
pointer on the HSI must be manually set to the desired track (DTK) indicated by the
GNS 530. For detailed autopilot operational instructions, refer to the JAA Approved
Flight Manual Supplement for the autopilot.
CROSSFILL OPERATIONS
For dual GNC 500 Product Series or GNC 500/GNC 400 Product Series installations,
crossfill capabilities exist between the number one and number two Systems. Refer to
the GNS 530 Pilot's Guide for detailed crossfill operating instructions.
AUTOMATIC LOCALIZER COURSE CAPTURE
By default, the GNS 530 automatic localizer course capture feature is enabled. This
feature provides a method for system navigation data present on the external
indicators to be switched automatically from GPS guidance to localizer / glide slope
guidance as the aircraft approaches the localizer course inbound to the final approach
fix. If an offset from the final approach course is being flown, it is possible that the
automatic switch from GPS course guidance to localizer / glide slope course guidance
will not occur. It is the pilot's responsibility to ensure correct system navigation data is
present on the external indicator before continuing a localizer based approach beyond
the final approach fix. Refer to the GNS 530 Pilot's Guide for detailed operating
instructions.
