Single Dme Installation; Toggling Active And Preset Frequencies - Honeywell PRIMUS 1000 Pilot's Manual

PRIMUSr1000 Integrated Avionics System
The message AUX ON is displayed at the top of the NAV window when
the NAV is being controlled by the tuning backup control head. The
RMU is then locked out from control of that NAV.
NOTE: Under certain circumstances, some integrated automatic
flight
tuning--inhibit signal to the navigation receiver that prevents
retuning the radio after approach course capture. If this
capability exists, the message INHIBIT is displayed in the
NAV window.
The upper right transfer key on the RMU bezel, shown in figure C--11,
toggles the active and preset frequencies to channel the NAV receiver
to what had been the preset frequency. The old active frequency moves
onto the line below and becomes the preset frequency.
NOTE: Whatever frequency is displayed in the top section of the
window is ACTIVE, whether it is on the main tuning page or a
memory page.

Toggling Active and Preset Frequencies

SINGLE DME INSTALLATION

Single DME installations operate the same as dual configurations.
However, the No. 2 NAV has an unused DME channel in the No. 1 DME
as its own DME. There is no No. 2 maintenance event log.
