GPS Select Selections:
Selection Description
Auto In GPS mode on the AeroNav XXX, the GPS Select discrete will not be
active (open) in a GPS approach, and no messages will annunciate on the
AeroNav XXX and no pilot action is required. This setting allows the pilot
to use the GPS VLOC Capture option on the User Options part of the
Setup tab on the AUX page.
Prompt In dual AeroNav installations, only the AeroNav connected to a KFC225
autopilot should be setup for prompt. In GPS mode, the user will be
prompted to enable the approach in KFC225 equipped aircraft When
Prompt is selected, and a GPS approach mode is active, a CAS message
will prompt the pilot to “Enable A/P Approach” on the FPL tab. At that
point, the pilot may then enter APR mode on the autopilot. This setting
will also ignore the GPS VLOC Capture option on the User Options part
of the Setup tab on the AUX page.
