vLOC To/Fr Radial Displays

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   When my 540 is switched to vLOC, either on an approach or just to navigate with a VOR, I am unable to display the To/Fr Radials on the 540:
.  540 v10.1
. VOR data block ID filled in
. External CDI in place (MD406-222)

Also have dual Aspens, and suspect "Priority" issues with PFD ARINC429 and CDI RS232.

On Maintenance page 6/12, there is a Maintenance Mode setting for the OBI Source --> "Always GPS".  What would happen if  changed to "Track CDI" - any changes in function with OBS, vLOC, or ILS for example?

Any help appreciated.

	Track CDI is the preferred setting. That should fix your issue.

	Is that only relevant when you have an external analog CDI present? * Orest
