Someone else asked about scratching the canopy:
. . . If visor is down in front of you, then a piece of soft leather or
similar on top of helmet protects canopy.
. . . If visor is up, then it will contact canopy - so, one might want to
put a bit (1 foot square or diameter) of "cling plastic" on canopy above
where your head will be. Lots of folks already have sun barriers above
them, which would protect the plexi.

Brian, my helmet simply has a snap on each side for attaching the elastic
strap on the visor. I can unsnap the clear and snap on the colored visor
when needed. I use the clear most of the time, for bird protection, with
sunglasses underneath when needed, so don't really need the tinted visor.

In combat in 1967 up "north" in Package 6, one day I told myself the visor
was bulletproof - I no longer suffered anxiety rolling in on a heavily
defended tgt. Prior to that I worried a bit about a 37 or 57mm in the face.
Piece of cake after I put on my bullet proof visor. Now the biggest threat
is buzzards, snow geese, and other large "mm" birds. Visor is real
protection in event of a birdstrike, not just make believe.

I just had 3M tinted window film (thin sheet of plastic) on my windows on
the Gulf Coast last summer - makes the windows rather "hurricane proof".
The website tells of a company putting these films on windows of a mobile
home "office" at some petro-chemical plant construction site - 3 days or so
later, there was a big explosion - trailer was blown over on its side but
windows were intact.
. . . I'm going to consider experimenting with that stuff on the front part
of my RV-6 tip-up canopy for bird resistance.

Dave,
Do like Boeing does, they heat the center windscreens of 757 and 767 to
improve bird impact resistance. I can attest to them working, I took a bird
right in the face, or in line with my face, didn't hurt a bit, the bird
wasn't in very good shape though.
A squadron mate of mine took one in the face on a low level Nav in an F-18,
he was so incapacitated that he crashed with no attempted ejection.
I'm with you on the visor thing, there is no better sunscreen and glare
removal.
For those considering a helmet, Flight suits offers active noise canceling
for your helmet. I personally would rather have thousand dollars in a
helmet than a thousand in a set of Bose.

Headsets, Inc., does the same thing for a lot less than FlightSuits.

Ah, you must be wearing the HGU-55. That is the more popular helmet than
the older (and clunkier) HGU-33 I wear. The HGU-33 I wear has the
tension knob that controls the visor.

I combat you have to tell yourself something or you won't be able to
make yourself go.

This seems to be more about systems. The helmet is part of your
communications and environmental systems. With an HMD (head-mounted
display) it becomes part of your navigation and systems monitoring.

I haven't tried their active noise reduction. My experience with ANR
headsets is that they lack the same level of passive noise reduction
needed to protect your hearing. (ANR only takes out the low frequencies
which do not cause hearing loss.) Does the ANR still preserve the
passive noise reduction?

And then there is the added complexity with its attendant reduction in
reliability.

No kidding. There are some Chinese AF helmets available on E-Bay. A
friend with a CJ6A got one. It looks pretty nice but does not have
earspeakers or boom mic. One would have to add those things but
otherwise the price is right.

Brian, they aren't equipped with earspeakers and boom mic because they
aren't needed---that's what the tin can and piece of string are for in
the accessories kit.

We tend to make fun of the Russians and Chinese as their stuff tends to
be less technically advanced than ours but having spent a fair bit of
time with their flying hardware has given me a healthy respect for what
they do. I really like the fact that they design their structures to
withstand 100% overload at failure instead of 50% as we do here, i.e. an
airframe rated at 6G by the Chinese or Russians is tested to 12G before
failure, not 9G as we do here.

And they do have intercoms in the Chinese aircraft. It is just that they
use vacuum tubes. (True!)

As I understand ANR, it blocks the low freq portion of the noise problem and
your passive catches everthing above that. The low freq stuff is not
affected by the passive noise reduction. A good helmet has great ear cup
seals, and a seal around the edge of the helmet to act as a first layer of
defense. This catches all but the low stuff.
ANR is just the icing on the cake, it aint the whole cake.

I've read that vacuum tubes are not affected by EMP, like
transistors are.

Well, they are affected but they recover without dying.

OTOH there is a company that manufactures an EMP pulse detector that
acts fast enough to apply clamp voltages to your solid state gear. Get a
couple of those and you can have a high tech solution to the problem.

And if you are worried about EMP, make sure you have at least one
old-fashioned mechanical magneto.

All kidding aside, the Chinese don't seem to be strongly motivated to
change. The CJ6A still has a vacuum-tube ADF with mechanically rotating
loop antenna, a four-channel crystal-controlled VHF comm, and a slaved
heading indicator that uses a rotating magnetic compass to provide its
magnetic heading reference (the magnets on the compass card are BIG so
there is enough force to rotate the synchro resolver). The latter uses a
vacuum-tube synchro amplifier. And all this stuff is powered by
dynamotors and rotary inverters. The turn-on surge is about 40A at 28V. Smile

But the stuff works really well.

Oh, and it isn't light. The aircraft wiring harness weighs 110 pounds.
The ADF antenna is 25 pounds. The ADF electronics box is 40 lbs. Each
control head is about 10 lbs. I could go on and on but you get the point.

Mark,
I've ridden Goldwings for years and have used the headset/mic units.
They should work, but I'm not so sure they would be any cheaper than a/c
stuff.
