The UK police are going NVIS as we speak (I know we are 15 years late!).
The important fact that will remain with NVIS operators is that :"...in the evnt there is a reversion to visual flight (unaided), the pilot must still be in a position to comply with the night VFR weather and visual requirements..."
Basically, NVG does not allow for departure from the exisiting visual requriements. You should not therefore be in a flight regime where your visual requirements for VFR are diminished.
NVIS will help us because of the topography of our force area Black and more black with some grey in between. We turn down some flights at night because we cannot see where the cumulo granite and the cloud base...meet. With NVIS, this should prove much easier to discern and thus the decision to go/no go is easier to make.
Long live NVIS
