ACMS - did you never fly 2-eng approaches and landings in the sim during your 744 time?
I have flown the B707, B747-200 and A340 and they ALL require you to maintain an approach speed above VMCA2 until a commit point and thereafter a speed reduction to Vref.
We used to do 2-eng base flying on the aircraft. For the B707 the go around procedure from 300` was to continue down the glideslope whilst accelerating with full power on the inner and as much power as could be obtained without losing directional control on the outer until enough speed was achieved to have full power on both - only then was a climb away started. The lack of rudder authority with too much thrust on the outer was very obvious.
