Included is a picture showing VOR approach HESH O4L. The red arrow shows approach heading to VOR SHM. Can this approach be performed using VNAV/LNAV with VOR LOCK at base turn to final? It works quite well with pmdg 737-700 but I'm not sure if this could be done in real life. Any thoughts ?

I can't think of any reason why not.

Now, in the case of VNAV / LNAV your following FMC and not using the VOR radio's to follow the radial.So VNAV/LNAV with VOR lock don't mix.If you want VOR lock then you are switching to another NAV mode.


FMC will follow a lateral and vertical path conform the procedure defined in the FMC.

(This means that a procedure will also be performed if setup correctly).


For a VOR approach one should descend according to the profile on the plate to MDA. But from there on, I fly manually tracking the VOR with the NAV radios and keep FMC as reference only.
