I can't add anything to the great info already here, but I won't let that stop me.

I bought three pairs of yellow/amber sunglasses I saw advertised by that great aircraft supplier "Sportmens Guide" (don't laugh, I got my nomex insulated flight suit, my magnesium snowshoes, and my 30 below sleeping system from them, all at great prices) that they were pitching as being great for flat light conditions. Intended for hunting no doubt but the price was right, I think they were about $35.00 for all three. I like to think they help, they look kinda cool anyway. They do seem to brighten things up.I also carry a much darker more standard pair for greater shading when needed. Like MTV said, in some conditions you're just screwed!

One situation I have not seen discussed, that happened to me. I was landing in a flat smooth field, with a falling down old farm building in the center of it. A grey day, but the touchdown was uneventful. Until that is, I slid alongside the building.
Without warning I got pitched back in the air, I got popped up maybe 5' or more and then dropped back down with almost zero airspeed. I never saw it coming.....what had happened was the prevailing winds in this valley are from the S, and you guessed it, I had chosen to slid out by the N side of the structure, right into the big hard drift that the winds had deposited on the downwind side. BTW, it was dead calm that day. And, the rest of the area was indeed nice and flat, like I had determined earlier. No damage done (and this really made me a believer in the Datum skis) and a good lesson learned, one that was obvious only in retrospect though.

A couple of weeks ago I flew from bright sunlight into the shade of a nearby mt., I was landing in a undulating bowl that had an average slope of about 15%. I lost my depth perception (which was razor sharp in the sunlight) as soon as I entered the shaded area. Commited to the landing, I figured no biggie and just did like the float pilots do and maintained a gradual descent. After a short while all of a sudden I realized I must have been much higher then I thought as I had not touched done yet, this all happened in split seconds: sitting there fat, dumb and happy and under control then a brief spurt of WTF as I got confused. THEN I noticed that no, I had indeed judged the remaining time to touchdown about right, while still out in the sun. What had happened was the light was so flat and the touch down was so smooth I had touch downed unawares! While I was freaking out I was already down. And yes I had my "special" glasses on that day. Luckily the bowl itself was as smooth as I had earlier guesstimated.

Yogi nailed it, ("you can't see what you can't see") I didn't know he was a ski pilot

Typical flat light kind of day. There are a number of terrain features here on the way out to the ski strip. But you can't see them.







In this case, this Cessna is hitting a wind drift. Gear don't love it.











often open water where streams come into the lakes. There are two inlet/outlets on my little lake, just have to be aware of them and don't land long if going north!

So, the other day since I made the post above, I was making a breakfast run and found myself once again over the area described above. Pretty easy to see on that day. I hit the drift/launch ramp right behind the barn on the left. Making it worse, the drift was higher towards the barn, sloped, so when I re launched it was cock eyed. The re landing was pretty much all on one ski at first anyway.

Flat light yesterday, land by the shore for reference...but also lots of overflow...
