Well, company policy is one thing, what the technology can do is
another. The map shift has nothing to do with it, the FD will
intercept the localizer signal and follow is just as it would if you
would tune it manually and intercept it on heading select.

no it won't, not if it intercepts the FMC track first and thats not in
the same place as the runway.


It will NOT, intercept, never, the FMC track, again as the LOC becomes
alive the FD will drop the FMC(switch from FMC guidance to navaids) and
intercept the LOC, the signal from the navaid, the FMC will again come
online only if you select it or if you select TOGA.


As you intercept the LOC you will not be using the FMS commands
anymore but the navaid signal.


IF you intercept it. That's the point and that's why we don't allow it.
We also consider it to be good practice pilot machine interface.
You're more in theh loop. Hdg sel only comes on when you're within a few
miles of interception if you're not already on it.

If the ILS is working you will definetely intercept it, there is
absolutely no difference if you intercept following the FMC guidance or
if you are on heading, you will intercept the ILS signal fro the navaid
on the ground.

You are always monitoring the instruments and the FMC and autopilot, or
at least I am. I don't believe you fly with the autopilot on, in any
phase of the flight without monitoring it
