Helmets - Should you? and Which?
Oxygen masks + Helmets
Does anyone have experience with oxygen masks fitted to helmets in civvy applications? I'm involved in a project where we are doing aerial photography and filming from a range of altitudes from sea level to 14k, mostly at night. While 14k's not up in the flight levels, we still need o2. Additionally, as for a lot of the missions we are operating door-off and photographer in harness, we've been looking into helmets for photographer and technician, for crash protection (they are on short tethers instead of secured with seatbelt) as well as birdstrike protection, and for better comms when one's head is out in the airstream.
I've seen the Gentex MBU-12/P masks (Pressure Demand) as well as the ALPS-M (Constant Flow). The Gentex is of course designed to work with helmets, but the pressure demand system is massive overkill for what we need. The ALPS-M system doesn't seem to work well with helmets, or at least would have to be donned separately.
What are helmet-wearers doing for oxygen (besides cannulas) in helicopters? Cannulas aren't an option as they wouldn't fare well in the door-off and moving-around environment.
EDIT: Found some information about ALPS-M conversion for helmet usage ( http://www.mhoxygen.com/index.php/co...s/download/645 ). Any feedback on these or other systems?

I know you said you are anti-cannula, but I've used the Aqua Lung PHODS for work similar to what you say you'll be in, up to 15,000ft, with no issues. The altitude based auto-start/stop and automatic O2 regulation is awesome. It's minimalistic compared to a mask, never interfered with shooting with a DSLR, and is a tiny overall package (and not hard mounted at all).

Helmet Cotton Liners
Does anyone have a good source for purchasing cotton helmet liners/skull caps without having to purchase from the USA and paying ridiculous delivery charges.

Using my helmet in a R22 or R44 is kind of a problem, as the low RRPM warning horn gets so muffled by the sound isolation of the helmet, that it's hardly noticeable. Therefore I prefer not to use a helmet on these aircrafts as I worry I won't hear the horn in a low RRPM situation. Is there any solution to it?

"... one day I had a solo flight to OKC for maintanance, and had my music cranked up a little louder than when I have pax with me (not excessivly loud) and was surprised that I could barely hear the horn on my check. "
The FAA Technical Panel Final Report (17 March 1995) proposed the following:
Design Changes
Provide low rotor RPM warning horn through the intercom system.
Design Changes
Provide low rotor RPM warning horn through the intercom system.
Then, in September I brought it up during the R66 course and Tim Tucker said "we tested the David Clark and the Bose and it wasn't a problem and it would add weight so we won't do it". I said it was a problem with my Lightspeed but they basically seem to feel that since nobody has died yet from not hearing the low RPM horn they don't need to address it (and of course if there is a fatal you probably won't know that the pilot couldn't hear the horn, just that for some reason he never lowered the collective).
So granted it's probably shouldn't be the top priority, but it's one that could be solved at modest cost and probably with no weight increase at all. Perhaps someone will do an aftermarket device...
Hard shell helmets.
Does anyone here have a recommend flying helmet? I have used Alpha helmets with ANR before for fixed wing flying but would be interested to hear if anyone has a favourite Rotary winged lid. Also, any recommended (or steer clear) of pilot flight equipment inspection centers in the UK? Thanks in advance! Edit - found a company in the UK called Key Survival who fit the bill, thanks for the PMs.

helmet without any doubt
This is the one my company provides. Give if a few tries and you will not want to go back to headsets. As someone has said, I feel weird and unprotected without it.

...To ANR:
My experience with a GENTEX SPH-5 and ANR in a AS350B3 is: "USELESS as soon as you open the window - forget it with the door off!"
It seems the noise pattern from the B3 rotor changes to fast for the ANR to pick up and cancel out.....
I suggest you safe the ANR and go for CEP....

Best pilot helmet?
Hi everyone,
I have an old MSA Gallet helmet which needs to be renewed, here in Spain pretty much everyone goes with this one.
After doing a search on what's on the market at the moment, I'm not sure which one to go for.
If you had to buy a new one, which one would you recommend? Evolution, Gentex, MSA ..?
Really appreciate your experience with this, they are really expensive so better not rush on the decision,
Thanks!

Used Gentex, Gallet and Alpha Eagle. Alpha Eagle is miles more comfortable (and adjustable) than the other two.
Also go CEP with moulded tips far superior than ANR in my experience.
