The reason for my question is because I've been practicing a few proceedures using PMDG's 744 simulator and a G/A is the only thing that seems totally unmanageable. It's probably just down to a lack of realism, but here's a clip of my attempt.
PMDG 744 Go-Around
Everything seems ok until 1000ft when I select VNAV. Watch the speed tape, is this a bit excessive?
