SUPPLEMENT
DME
(TYPE 190)
SECTION 1
GENERAL
The DME 190 (Distance Measuring Equipment) system consists of a
panel mounted 200 channel UHF transmitter-receiver and an externally
mounted antenna. The transceiver has a single selector knob that changes
the DME's mode of operation to provide the pilot with: distance-to-station,
time-to-station, or ground speed readouts. The DME is designed to operate
at altitudes up to a maximum of 50,000 feet at ground speeds up to 250 knots
and has a maximum slant range of 199.9 nautical miles.
The DME can be channeled independently or by a remote NAV set.
When coupled with a remote NAV set, the MHz digits will be covered over
by a remote (REM) flag and the DME will utilize the frequency set by the
NAV set's channeling knobs. When the DME is not coupled with a remote
NAV set, the DME will reflect the channel selected on the DME unit. The
transmitter operates in the frequency range of 1041 to 1150 MHz and is
paired with 108 to 117.95 MHz to provide automatic DME channeling. The
receiver operates in the frequency range of 978 to 1213 MHz and is paired
with 108 to 117.95 MHz to provide automatic DME channeling.
All operating controls (except for a SPEAKER/PHONE selector
switch mounted on the audio control panel supplied with one or two
transmitters as described in Section 7) for the DME are mounted on the
front panel of the DME and are described in Figure 1.
