VHF NAV Bearing Pointer
The bearing pointers may be selected from the PFD Main Menu, BRG SRC submenu. Actuating
the BRG SRC button on the display control panel (DCP) provides direct access to the bearing
source submenu. The submenu includes a VOR selection, which allows bearing data and
pointers to be presented on the ROSE and PPOS formats on the PFDs and MFDs.
Bearing indications are accompanied by VOR station identification, as well as aircraft distance
to bearing source. Bearing distance and station identification are not displayed if the bearing
source is also the active NAV source. Bearing distance is removed if DME hold is selected, or if
the VHF Nav radio is tuned to a localizer frequency.

DISTANCE MEASURING EQUIPMENT (DME) SYSTEM
Description
The aircraft is equipped with two DME systems. Each DME system provides calculations of slant
range from the aircraft to the DME ground stations. The information is used for position fixing,
enroute separation, approach to an airport, holding a given position, and determining ground
speed.
Components and Operation
Each DME system includes a DME transceiver, located in the avionics compartment, and a DME
antenna, located on the bottom of the fuselage.

DME Audio
The DME 1 and DME 2 controls on the audio control panel are used to turn ON or OFF, and
adjust the volume of, the DME transceiver audio. The DME morse code identifier is supplied to
the audio integrating system. When listening to the NAV idents simultaneously, the DME is
recognizable by its higher pitch.

DME Tuning and Control
DME operating frequencies are paired and tuned with the VHF Nav frequencies. Each DME can
continuously scan up to three channels. One channel is manually tuned, and provides data to
the flight displays, while the remaining two channels may be automatically tuned by the FMS,
and are used for multisensor navigation.
DME Hold
A DME hold function allows the crew to maintain a DME tuned to one frequency, while tuning
the VHF Nav to a new frequency. This function is enabled via the CDU TUNE page, by
pressing the line key adjacent to the DME legend. The HOLD text enlarges when selected, and
the frquency being ’held’ is shown next to it.
The Hold function may also be selected by pressing the DME-H button on the cursor control
panel (CCP). When pressed, the focus indicator on the MFD moves to the NAV recall
frequency, allowing the VHF Nav to be tuned to a new frequency.
Independent DME Tuning
Independent tuning of the DME may also be carried out via the FMS CDU. This feature allows
for a separate DME frequency to be tuned without having to select HOLD. This is done by
entering a DME frequency onto the CDU scratchpad, followed by selecting the desired DME
line key. Independent tuning in this manner cannot be carried out from the MFD tuning window.
DME Display
DME information is displayed on the PFDs and MFDs. The information is listed on the active
navigation source data block on the PFDs. The DME distance includes the abbreviation “NM”
(nautical miles) when DME tuning is coupled with the VHF Nav frequency. The abbreviation
“NM” is removed and replaced with “H” when DME hold is selected. DME information is also
presented in the same color as the navigation source. DME and related indications, such as
time-to-go, are also provided at the top of the MFD. The color of the DME data presented on the
MFD also corresponds with the navigation source.
