That sucks

I had a friend here in Payson who landed his show quality 195 into the sun one evening and went off the runway and tore out a gearbox.

There was a nieghbor at Stuart Island that tried to land into the sun one evening and hit the tops of some trees on an angled short final because she was blinded suddenly by the sun on the water. She dropped about 50 feet and pancaked it in upright near a ditch. Walked away without a scratched but her Cherokee was totalled.

The sun is nothing to mess with.

I was landing my 140 late one afternoon at Hartford in Wisconsin directly into the sun and everything was fine. Then as I was touching down the RPM's must've hit just the right spot with my eyes and I got a stroboscope affect and couldn't see squat until I looked down for a couple seconds. Then I kinda squinted a lot and looked off to the side a bit to finish the roll out. Quite a startling experience. Never had that happen before.

I've heard of a condition called "flicker vertigo" which is supposedly brought about by that strobe effect of the sun behind the propeller.
Never experienced it myself- has anyone ?
Rudy

Yes, just ask any helicopter pilot who has gone under the hood on a sunny day. If the conditions are just right it will certainly induce vertigo. Nothing like practicing while experiencing the real thing!

In a physics class many years ago, we had an adjustable strobe light. In a darkened room the prof intentionally set the frequency in the range of 1500-1800 flashes per minute. He then asked if anyone had experienced vertigo. The majority of the class had. He explained that when the flash synch's with the frequency at which the brain operates spatial disorientation ensues. The frequency varies with the individual. My first flight instructor commented about the same effect one late afternoon when we were doing touch-and-goes to the west. It can also induce irritability. For example, ever notice when taking an afternoon drive northward along a road lined with trees on the west side that the flicker effect of the shadows is uncomfortable? It is definitely not something to play with.

When I installed my Whelen wingtip strobes (double-flash model) I first set them to triger simultaneously, but I quickly realized that it made me drunk. I then reset them to flash alternately....first one wingtip then the other... and no further problems.

Hey George you should set that system up at home for a cheap happy hour

The lights at work must be in that same frequency range, I'm allways irritable there.

Was this in the clouds, or on the ground at night? Normally, from the cabin I can't even tell if the wingtip strobes are flashing. Drunk or not.

I refuse to buy from Ce$$na because they are the most hateful bunch I have ever encountered when it comes to pricing. I figure they buy a part and add at least one zero to their cost. Anybody have any crossovers?

I ordered a foot of every different style of U-Chanel that Aircraft Spruce carried that looked like it might be useful. There were only 3 or 4 as I recall. I tried them on the various pieces and figured out how much of each I needed and ordered it. I think two sizes covered it all. Sorry, I don't have the part numbers.

Walker, try http://www.aircraftspruce.com 877-477-7823 who sells most of the black rubber U-channel, or http://www.brownaircraft.com who sells an incredible amount of rubber mouldings of various shapes/sizes.
