VOR and DME frequency are again the same. The DME HOLD
button will remain depressed (it is a two-position button). Thus the
HOLD button functions as a Hold “ARM” when in the “in” position
and actual Hold (HLD) annunciation occurs
only when VOR/ILS
and DME frequencies are different.
If you should mistakenly try to use the HOLD function in
RNAV modes, as soon as the frequency is changed the HLD
function will annunciate, DME displays (NM,
KT and MIN) will flag
(display dashes) and the CDI or HSI will flag since this
is not a
valid RNAV signal. Use
of HOLD in VORlPAR mode will result in
a CDI or HSI flag (unless an ILS frequency is selected) and the
DME displays will be
to the VORTAC on “HOLD”.
RNAV Approach
17. We have now touched on all modes and operations of the KNS 80
except RNAV Approach (RNV/APR).
The RNV/APR mode may be used for runway location (by
placing
a waypoint at the approach end of the runway) during an
approach
to an airport.
If you are in RNV/ENR mode, depress the RNAV push button
and the RNV/APR mode is immediately activated. In RNV/APR
the deviation needle on your CDI will display crosstrack deviation
as
+1Y4 nm full scale, or Y4 nm per dot. All other aspects of the
RNV/APR mode are identical with the RNV/ENR mode.
