Hello all

On recent flight the INS managed to bork itself so attempted to revert to VOR. I changed the switch on the captains side cockpit from INS to radio but while it seemed the HSI needle was tracking the station, the DME itself was frozen on 12.5. The DMEs on the RMIs did seem to track. Had DME set to on with the nav radio (both nav 1+2). Scoured the manual just to confirm it wasn’t user error but couldn’t find anything I might have missed. Hopefully someone else knows where I screwed up. As mentioned this is on 1.0.5

AS strange as it sounds the HSI only displays DME for INS waypoints, so if you switch to VOR even though the HSI shw VOR course/direction, the DME is still showing INS distance. DME for VOR1 and VOR2 are shown on the small HSI gauge to the left of the main HSI. You have to have DME switches on the AP panel toggled to 'normal' too. Makes no sense to me but is supposed;y how it was on TriStar.

As Agfors said, the HSI DIS/TIME Readouts are only driven by the INS Computers and are NOT coupled to the DME on the Tristar based on all the refs we have.
