The NVGs you listed are fine, definitely better than the first ones that I
used. They are biocular, i.e. they use one image intensifier with a beam
splitter into two eyes. That means that you will get blanking if you happen
to look directly at a canopy strut, but you just look to one side of the
strut or the other, and they are obviously cheaper.
The instrument issue is not difficult. Use green electro luminescent strip
lighting and turn all the other lights off; I plan to use EL anyway because
they give good cockpit illumination. Then go and buy samples of different
red transparent film, get into the cockpit and get someone to throw a cover
over it. Try the different films in front of the NVG optic until you find
one that is not dazzled by the EL light. Tape the film that works on the
front of the optic and you are done. You look around the eyepiece to read
your instruments, the object of the film is to avoid swamping the NVG with
light. Oh, and get rid of the rubber eyecups shown in the brochure, you
don't need them and they cause disorientation.
If you need more detailed information, please email me direct. I can go on
at boring length. (I know, I just did!)

Jerry,
Thanks for the great info. You raised some issues I hadn't
thought of. I had originally planned to kill all of the lighting in an
emergency, but I forgot about the focus range and reading the
instruments. I
looked through a monacle (ITT Night Enforcer I believe...) and definitely
see
how light sensitive they are. I guess the main problem would be dealing
with
viewing the instruments, in which case I'm not sure how that would be
done! I
had been thinking of something like this (or around the same price range):

Could anything be done about instrument viewing? Thanks for the input. I
did get a couple of the usual LML smartass replies, but they might think
differently if they have an engine fail if they fly at night, which I know
alot of them do. A thousand bucks is worth improving my odds.
