I have an integrate d system in my -10 which was the right call for that plane but I don=92t see the need for a permanently fixed bottle on the 8A for my mission. I can see a removable bottle or even just a bottle & padded pouch to place in the cockpit for occasional X-Country use and no hard mounting of O2 pick up locations. Does anyone have a suggestions / photos of the systems they use? I am looking for practical solutions, not full blown O2 system in the forward baggage & routed hard lines. Thanks, Robin ________________________________ Message 2 _____________________________________ Time: 06:40:43 PM PST US From: Matt Dralle Subject: RV8-List: Bose A20 Headset - NR Power Button - Panel Power Dear Listers, I bought a couple pairs of the new Bose A20's for the RV-8 and they are very nice. NR is better than the Bose X's and they seem to fit my head a little better too. But I quickly discovered that with the A20's you now have to hit the NR Power button *every time* you start the aircraft even if you have them panel powered. The older Bose X headsets have a slide switch for the NR power and so you can just put the slide switch in the On position and not worry about it. I really didn't like having to turn the NR on all the time and having to remind my passengers about it, so I came up with a modification that will automatically turn the NR on when panel power is applied. Its pretty simple, but requires some special tools. Its completely self-contained inside the Control Module and works great. The modification is generally only for installations that are panel-powered, but you could do the modification to a unit that is normally battery powered with no adverse effect. With the modification, the NR Power button will work normally in battery power installations. I created web page on the procedure including step-by-step photos and instructions. Feedback is welcome. http://www.matronics.com/BoseA20AutoOnModification/ Matt - Matt Dralle RV-8 #82880 N998RV "Ruby Vixen" http://www.mattsrv8.com - Matt's Complete RV-8 Construction Log http://www.mattsrv8.com/Mishap - Landing Mishap Rebuild Log http://www.youtube.com/MattsRV8 - Matt's RV-8 HDTV YouTube Channel Status: 170+ Hours TTSN - Rebuilding Fuselage After Landing Mishap... ________________________________ Message 3 _____________________________________ Time: 09:20:33 PM PST US From: Speedy11@aol.com Subject: RV8-List: Re: Max wind speed limit No. Stan Sutterfield Okay, let me expand on my response. Who is to decide what the proposed max wind speed limit is? And how is the speed determined? Does one choose the touchdown speed (say 60 KIAS) as the max wind speed limit since that wind speed would result in a hover landing (assuming one is landing into the wind)? And who, on the scene, determines that the max wind speed limit has been reached? The tower? How about at an uncontrolled airport? The AWOS? I suggest that the pilot in the airplane determines the max wind speed limit for him/herself. Each pilot knows his own skill, total experience, recent experience, time in type, and immediate weather conditions. Each pilot should decide for himself if landing in given conditions is suitable or not. Having a max wind speed number determined by "someone" beyond which pilots may not land is not appropriate. I have landed a taildragger in 75 knot headwinds and a C-172 in 25 knot crosswinds. Landing is not the difficult part - it is the taxiing. Taxiing a C-172 in 25 knot winds is very challenging and requires careful planning. Taxiing a tail wheel aircraft in calm conditions is challenging and requires careful planning - winds can compound the problem. I suggest that we already have too much "outside the cockpit" interference now. Adding another restriction to bring everyone to the lowest common denominator is not the solution. Thinking about and planning for and practicing for the situation is the solution. It sounds as if Matt did nothing wrong during his landing other than trying to make an early turnoff. A max wind speed limit would not have reduced the likelihood of his bent airplane. I appreciate that Matt has generously shared his situation with us. It allows us all to learn without having to experience the same outcome. I'm not sure if I'd have been so generous. Okay, rant over - flame suit on. : ) The answer is still no.
