Yes exactly, new on the Boeing, formerly 3 years on the 320.
I am at the very beginning of the type rating, we saw this this week.

Okay, so the default speed is indeed 240 knots before final approach, and 170 knots for final approach. However, I don't see in which case we would engage VNAV during final approach. Except maybe a mistake or a change of plans, at least I don't see a situation where we would plan to engage VNAV during final approach.

Where is this written ?

Many thanks

I'm pretty sure that everything that will need to be done, will be doable one way or another, however this one seemed surprising.
The other "problem" with VNAV is that you can't change the speed, while keeping the profile, except if you change the cost index, but apparently it's not boeing philosophy to do so?
