PatternIsFull, is that irrespective of weight and icing conditions in Your company?
For a heavy aircraft, this seems rather on the slow side, seeing that V2 without ice increment at flaps 5 and MTOW is already nearly 140kIAS (with ice, above 1000ft, it even shows 158kIAS).
Here, we have a speed called Vfri (Flap Retraction Initiation), which is at V2+10 and therefore takes weight, icing conditions and a possibly deiced wing (as well increasing the V speeds in my company) into account. It must obviously be achieved before starting to raise the flaps. As a nice little side effect, Va is nearly equal to V2+10 for a given flap setting (+/-2kIAS), so in a go around, raising the flaps at just a bit above Va with NTOP set is appropriate as well - no need to tamper with those speed bugs in an already high workload situation.
