IFD500 Series Pilot Guide
6-24 Navigation
NOTE FOR THE IFD510/545 ONLY
VHF based Approaches
Although the IFD510 and IFD545 have no VHF
radio, ILS, LOC and VOR approaches will still be
displayed in the dropdown list of available
approaches at your destination. Though the unit will
allow the user to select those approaches, it will only
give GPS overlaid lateral guidance. The unit will
provide no vertical guidance on an ILS approach.
Any guidance is advisory only as these types of
approaches should be flown with the NAV radio and
not the IFD.
AUTOMATIC MODE SWITCHING †
Automatic mode switching to VLOC (e.g. GPSVLOC transition),
including automatically setting the inbound course, will occur if
the capture criteria defined above are met and the primary nav
frequency can be auto-identified. If auto tuning has not been
enabled on the setup pages, or a station cannot be identified,
automatic mode switching will not occur.
TIPS AND TECHNIQUES
Exception to Automatic Nav Mode Switching
If VLOC mode had been previously manually
selected to be the nav mode (e.g. cross-tuning a
VOR) and then an approach is activated in the flight
plan that would have normally resulted in a
GPSVLOC nav mode indication, the nav mode will
NOT toggle to GPSVLOC. Instead, it will stay at
VLOC since it is assumed the pilot intended to keep
using the previous function. Likewise, the approach
nav frequency will be inserted into the standby nav
frequency slot but not the active nav frequency
position. Both the nav mode transition and the
swapping of the nav frequencies will have to be
manually performed by the pilot.
