However, there is a lot of discussion on other threads about the 'threat' of the Autothrottle potentially having no wake-up mode when using FLCH or V/S on a visual approach using the autopilot.

Is it just me who finds the idea of using V/S or FLCH in the last 500' of a visual approach absurd? Would any posters on here really do this?
Not having a go at you, Mr GC, but this is a good example of the fact that knowledge of the AFDS is lacking in otherwise competent guys, and yes, that is a failing of the training department and needs addressing.

A/T wake up IS available in V/S, as the A/T is in SPD mode.

The times it is not available is when the A/T is in HOLD, which is a few seconds after the thrust is at idle in FLCH and VNAV SPD.

As to use of those modes on approach, you really have to spend some time with an Asian carrier to get a grasp of what dependence on Automation is really like.
