5. DME TUNING Window (NAV1, NAV2, HOLD)
Allows access to the DME operating mode as follows:
NAV 1 Selects DME operation
with No. 1 VHF naviga-
tion set; enables chan-
nel selection by NAV 1
frequency selector con-
trols.
NAV 2 Selects DME operation with No. 2 VHF navigation set; enables
channel selection by NAV 2 frequency selector controls.
HOLD Selects DME memory circuit; DME remains channeled to station
which was last channeled when HOLD was selected and will
continue to display information relative to this channel. Allows
both the NAV 1 and NAV 2 navigation receivers to be set to new
operational frequencies without affecting the previously selected
(HOLD) DME operation.
In the HOLD mode, the frequency being held
remains in the DME Information Window and
does not update when NAV1 or NAV2 frequencies
are being updated.
If NAV1 or NAV2 are red-x'd on the PFD, the
associated DME indication will be valid if it was
the active DME when the NAV failure occurred.
Switching to the DME associated with the failed
NAV will not be possible.
