SECTION 4 - NORMAL PROCEDURES (continued)
E. 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 at the point of course intercept on a
localizer at which GPS derived course deviation equals localizer derived
course deviation. 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.
F. DISPLAY OF LIGHTNING STRIKE DATA
Lightning strike data detected by the BF Goodrich WX-500 Stormscope will
appear on the moving map and weather pages of the GNS 530. For detailed
operating instructions regarding the interface of the GNS 530 with the
WX-500, refer to the WX-500 Pilot's Guide and the GNS 530 Pilot's Guide
Addendum for the WX-500 Stormscope interface.
During activation and deactivation of the air conditioning
system, false lightning strikes/cells may appear on the
Stormscope display due to electrical interference caused during
operation of the air conditioner condenser door motor. This
phenomenon will also occur during air conditioning operation
with movement of the throttle between full and partial power
due to the automatic retraction and extension of the air
conditioner condenser door with throttle movement. False
lightning strikes/cells can be cleared via the remote
Stormscope clear button on the panel or using the controls on
the GNS 430/GNS 530 if so equipped.
G. DISPLAY OF TRAFFIC ADVISORY DATA
Traffic data detected by the BF Goodrich SKYWATCH
System (TAS) will appear on the moving map and traffic display pages of
the GNS 530. For detailed operating instructions regarding the interface of
the GNS 530 with the SKYWATCH, refer to the FAA approved Flight
Manual Supplement for the SKYWATCH, the Pilot's Guide for the
SKYWATCH and the GNS 530 Pilot's Guide Addendum for the
SKYWATCH Traffic Advisory System interface.
