Track a VOR Radial B777 (Explained)

Hello,

I am using jetmax 777 with O/H panel. I am looking for how to track a VOR Radial by setting up the MCP and fly in raw data mode.
I have set up VOR freq and course in the FMS (RAD/NAV page) and I have tried to press LOC switch on the MCP but the A/P don’t catch the radial (as we can observe on the B737 in VOR LOC mode).
I have tried several interception with low angle without success in that mode.
Could someone give me some help?

Thanks in advance.

There is no VOR track in the 777.
As the button says :
777 = LOC
737 = VOR LOC

I think a VOR intercept would be done via an intercept CRS to a waypoint in LNAV.

To do that you would enter the VOR into line 1 on the LEGS page.
After entering the wpt into line 1, the fmc assumes ‘Direct To’ and draws a line from the AC current position to the waypoint. But in the Bottom Right LSK an INTC CRS prompt appears. Here you would enter the inbound course you wish to fly and this course line is draw on the ND.
You can now execute this and LNAV will track this inbound course to the waypoint.
