FliteLine VHF Navigation System (FliteNAV and FliteDME)
General Description CVN-251
The FliteLine CVN-251 is an all digital DSP Navigation System which combines VOR/LOC, Glideslope and
Marker Beacon functions. This Receiver configuration supports the total navigation interface requirements for
MFD or moving map displays. The ARINC 429 digital data bus offers compatibility with EFIS/LCD displays, the
Chelton RMS-555 Radio Management and Flight Management Systems by supporting Nav auto-tune operation.
Additional interfaces are provided to HSI’s, CDI’s and RMI’s to include analog. Automatic calibration of the VOR
converter ensures navigation guidance accuracy. The CVN-251 is interchangeable with Series III VHF Nav
Receivers using a special mounting tray adapter.

General Description CDM-451
The CDM-451 is an all digital DME. The triple channel scanning DME provides ARINC 429 outputs along with
analog outputs for two displays or EFIS MFD’s. The CDM-451 Transceiver is compatible with FMS Systems to
include auto-tune operation. The third output channel can also provide single DME output to the FMS for
independent navigation solution. The Receiver can be tuned via ARINC 429 bus via the CVN-251 or Series III
NAV Radio using individual CVN-252 Nav Control Displays, the Chelton Series III RMS 555 Radio Management
System, or with Flight Management Systems. The CDM-451 is interchangeable with the current Series III DME
using a special mounting tray adapter. DME data may be optionally displayed with the SD-442 display
controller.
