Thought the list would benefit from this... and maybe keep all of us a little safer
in the skies.
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.

I think you'll be ok with 1/4". 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.

That's amazing. I knew the condition exists but have never seen it
demonstrated before.

Parting out my project was the last thing I wanted to do, but I guess I
have no choice. 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,

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!

I don't have any pictures of the modification. 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.
