Atc Transponder And Tcas Operations; Controls And Annunciations; Dme Function Key Operating Procedure - Honeywell PRIMUS 1000 Pilot's Manual

PRIMUSr1000 Integrated Avionics System
When the NAV window is split, an amber H (hold) is displayed in the
lower (DME) window. The H indicates that the distance display (DME
or TACAN) is not paired with the VOR/ILS navigation data. When the
H is displayed, the other aircraft systems HOLD annunciators also light.
Display of the DME (or TACAN) channel being held positively identifies
the navigation channel. The DME station identifier is also displayed.
NOTE: It can take up to 2 or 3 minutes for the station identifier to be
displayed.
The DME function key operation is described in table C--3.
Step

the upper half VOR/ILS tuning and the lower half DME
channel tuning.
2 Move the cursor to the DME window (lower) and tune
115.60, as shown in figure C--13. PXR is the identifier for
that channel. An amber H is shown.

line select key and tune 108.30.
4 When it is no longer necessary to hold the DME channel,
cycle the DME function button until the split is removed
