Figure 16-120. Universal Weather Menu
Use the CCP MENU ADV and PUSH SE-
LECT knobs to move the cursor and select the
desired weather image from the menu. The
displayed image and corresponding time of ef-
fectiveness will appear on the MFD. The image
is static and cannot be zoomed in or moved
around. If weather from an adjacent area is de-
sired the appropriate image needs to be re-
quested from the CDU and then viewed when
received.
COMMUNICATION/
NAVIGATION SYSTEMS
The Pro Line 21 avionics system uses either
the Control Display Unit (CDU), or the Radio
Tuning Unit (RTU) to tune the communica-
tion and navigation radios and the transpon-
der. The CDU and RTU provide redundant
control of all devices. Reversionary control is
provided should one unit fail.
RADIO SENSOR SYSTEM
The Radio Sensor System provides the control,
displays, and sensors for VHF voice communi-
cation, VOR/ILS/DME, ADF and transponder
tuning, and TCAS II (if installed). The system
consists of the Radio Tuning Unit (RTU-4220)
located in the center instrument panel, and the
Control Display Unit (CDU) which is located
in the pedestal. The RTU is considered to be
the primary method of tuning, with the CDU
functioning as the secondary method of tun-
ing. The tuning capabilities of the CDU are ac-
cessed by using the TUNE page. If Dual
CDUs are installed, only the left CDU
(CDU 1) has radio tuning capabilities.
A RTU/CDU TUNE switch is located on the
reversionary panel (Figure-121). When this
switch is in the NORM position, radios may be
tuned using either the RTU or the CDU.
Should the RTU become inoperable, tuning
the No. 1 radios (COM1, NAV1, ADF1, etc)
will not be possible. If the CDU should be-
come inoperable, tuning the No. 2 radios
(COM2, NAV2, ADF2, etc.) will not be possi-
ble. Moving the RTU/CDU TUNE switch to
the operating unit (CDU or RTU) will return
full tuning capability. If the RTU is the only
unit still operating, selecting RTU will allow
that unit to tune both the No. 1 and No. 2 ra-
dios. If the CDU is the only unit still operat-
ing, selecting CDU will allow that unit to tune
both the No. 1 and No. 2 radios.
