Motion Induced Blindness - video ATC, radar controllers and pilots know this but who would have thought about drivers. Unfortunately we know that's not a problem for the people texting while driving. Indirect observation is pretty critical for preserving night vision while driving at night also. This is frightening! It works exactly like it says, and is one major reason people in cars can look right at you (when you're on a motorcycle or bicycle)--- AND NOT SEE YOU. >From a former Naval Aviator. This is a great illustration of what we were taught about scanning outside the cockpit when I went through training back in the '50s. We were told to scan the horizon for a short distance, stop momentarily, and repeat the process. I can remember being told why this was the most effective technique to locate other aircraft. It was emphasized (repeatedly) to NOT fix your gaze for more than a couple of seconds on any single object. The instructors, some of whom were WWII veterans with years of experience, instructed us to continually "keep our eyes moving and our head on a swivel" because this was the best way to survive, not only in combat, but from peacetime hazards (like a midair collision) as well. We basically had to take the advice on faith (until we could experience for ourselves) because the technology to demonstrate it didn't exist at that time.

Pretty sure that's what I used. I can measure this weekend. Slightly different topic: The attach lugs that form the hinge at the top of the gear legs are welded on in a cantilevered arrangement. On the advice of the FAA, I wrapped and welded thin steel finger reinforcements over the top of the lugs and then down onto the gear legs. That gives several inches of welded support to the lugs instead of approximately 1.5" of welded support in the case of the cantilevered arrangement. There's a reason I point this out. -------- Kevin "Axel" Purtee NX899KP Austin/Georgetown, TX Read this topic online here: http://forums.matronics.com/viewtopic.php?p=365455#365455 ________________________________ Message 4 _____________________________________ Time: 10:47:51 AM PST US From: "C N Campbell" Subject: Re: Pietenpol-List: Motion Induced Blindness - video That's amazing.

I have a Continental A-65-8 with carb, mags,hub,and logs, on engine stand.Asking $3,000.00 I also still have my GN-1, partially built, but ALL the wood necessary to complete it is here, spars, sheeting, all of it. All but a few of the necessary metal fittings (laser cut), aluminum t.e.,jigs, plans. Asking $2,000.00. Even if you look down upon the GN-1 as inferior, the wood is worth the price for building a "real" Piet. Thank you, Dan Gaston Norwalk, Ohio ________________________________ Message 6 _____________________________________ Time: 11:55:03 AM PST US Subject: Re: Pietenpol-List: Re: Steel LG Lug Thickness From: Mark Roberts Thanks for the advice on the added reinforcement. Do you have a pic of what you are describing? I am trying to visualize it and am having a bit of difficulty picturing in in my mind... Is what you are describing simply wrapping thin metal around the lugs on the legs of the LG and welding them down the tubes a bit? Or doing something like this on the lugs of the LG mounts where the LG meets the fuse? Thanks Kevin!

Sorry. Here's a photo of the location I'm talking about. And yes, I'm talking about wrapping metal over the top of these lugs and down the gear legs 1.5" or so. Obviously the metal reinforcement is clearanced between the lugs. If you're a good welder you probably wouldn't need to worry about it. I'm an amateur and I've had well-documented problems with these welds so I took the FAA man's advice. -------- Kevin "Axel" Purtee NX899KP Austin/Georgetown, TX Read this topic online here: http://forums.matronics.com/viewtopic.php?p=365490#365490 Attachments: http://forums.matronics.com//files/landing_gear_top_lug_197.gif ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message pietenpol-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Pietenpol-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/pietenpol-list Browse Digests http://www.matronics.com/digest/pietenpol-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
