A winter tow today!!! With the wind blowing 25 mph right down the runway out of the west we could be at 1000′ over the main hangar when we got there! Of course we’d have some difficulty seeing the Pawnee at first with all the blowing snow and all, but like I used to do in Arizona you can just follow the tow rope until you’re able to see the tow plane! (Been there, done that multiple times, only it was dust not snow.) Lets just keep towing to the west ’cause at 1000 agl we have a westerly at 35 mph. Going up to 4000 agl we’ll need to head to Coral because our westerly has become northwest and it’s now blowing 56 mph. If we’re in a 1-26 we’ll make this flight last longest at minimum sink speed around 30 mph. We’ll need to continue northwest as we’ll be traveling backwards over the ground at that speed! Don’t let the field get too far away. Finally I’ll assume you did good and kept the field in glide. You’ll need to plan your pattern carefully. Since we’ll have an extra 35 mph on down wind and we’ll add 17 mph to our pattern speed to account for the wind we’ll be booking right along. That runway will be out of reach if we don’t pay close attention. If we turn base at the east hangar drift should put us at about the right spot over the runway when we get there. Turning base to final just east of the east hangar will look much different as we’ll still be fairly high (assuming you started your pattern at 1000′.) However that 25 to 30 mph wind will make your descent much more vertical than you’re used to. You may not even get back near the tie down area! Whew, made a beautiful landing and everyone came out to hold the ship down. A 1-26 without the pilot’s weight could easily fly if a 25 mph wind had a gust of an extra 5 mph in it.
I wish to thank all the members who not only work on the maintenance items, but who support the club in ALL that it does. Thank you, Merry Christmas and Happy New Year!!!! John Lincoln

Merry Christmas! If your flight did not work out that well I am on standby to provide medical aid since the frozen ground will be as hard as cement…the freezing point of human blood is -2℃ to -3℃. From studies done , blood freezes around 31 degrees F. It is lower that the freezing point of water (32F) because of the dissolved materials in it. Be safe.

If John launched from Arizona at 0500 he should be here in about 2 more hours.

Andy has found just exactly what it was like to launch on a dusty dry runway. Basically IMC conditions for the first 8 to 10 seconds. Seems scary the first time or two that you do it. You can actually learn how to keep the wings level while making this kind of launch. If you do this you will notice that while you can’t see the horizon you can (and I did) notice that if you looked up 20 to 30 degrees the sky is lighter. Keep the wings level and sort of horizontal to that lighter sky while also following the tow rope and you’d be ok. After the tow plane gets going the amount of dust goes down and the IMC condition disappears. The biggest down side is your sailplane is covered with dust. (So much for cleaning it before takeoff.) And now you all know why the glider operations in Arizona that use tow planes to launch also use paved runways to launch. Merry Christmas John Lincoln
PS. Andy, just one small under powered Reindeer! I might be a bit late Steve. Can I have a couple more hours!
