Thanks a lot Ron. We are looking at introducing Primary missions (Scene calls) at night here, and we will only be conducting them if NVG's are used. At the moment we fly Secondary missions, ie hospital transfers, only at night, and that is only into known airfields or Hospital pads.
You are right about the weather minimums. They will not change at all for us, we will just be able to see a little better!
Other than ITT, who else produces NVG's to the current standard? ANVIS-9 is the standard at the moment, is that correct?
What are the differences between ANVIS-7 and -9? I will check out DEP.
Cheers BM
