It is probably quite difficult to test out in the aircraft, making a (short time) barometer adjustment will not allow the subscale change to be immediately presented to the VSD and EGPWS. This is seen when passing through transition. It takes some time for the new QNH to be recalculated by these devices. So unless an incorrect QNH was set from some distance out, the VSD display will initially use the previous inputs.
The simulator used was a late model full motion, airline simulator, but I guess there could be software issues.
Cheers
