FliteLine Dual VHF COM and VHF NAV Control Display System
General Description
The Chelton CCN-955 Com/Nav Control Display Unit combines the capabilities of the CVC-152 and CVN-252
Control Displays.
The CCN-955 splits the screen displaying the communication transceiver data on the upper half and the
navigational data on the lower half. Despite combining the two radio functions all functionality remains
operationally equivalent. The CCN-955 adds functionality to the Power (on/off) button allowing it to be used as
a momentary button to toggle between the Communication and Navigation controls.
The CVC-955 is designed to interface with Chelton FliteLine Communications Radios (CVC-151) and Navigation
Radios (CVN-251), Chelton Series III Communications Radios (VC-401B and VC-401C in the VCS 40 systems)
and Navigation Radio (VN-411B in the VNS 41 system), and Collins Communication and Navigation Radios with
the ARINC 410 (2x5) Interfaces.
Limitations
NOTE: Installations of the CVN-252, and CCN-955 with the Series III or ARINC-410 digital interfaces which
include the optional DME Hold functionality are subject to certain limitations. In these installations, the aircraft
shall provide indication of the DME Hold status on equipment other than the FliteLine Control Display and within
the pilot's primary field of view.
Failure to meet these limitation guidelines violates the installation guidance set forth in this manual and may
lead to an unsafe aircraft operating condition.
