So I was at the restaurant between having just finished a cheeseburger without the bun (working on that 30 BMI), and waiting for the pineapple cake and ice cream to arrive, and I got to thinking about the 3-2-3 point landing as well as the 2.5 point landing.

It was at that point that I realized the whole 2 point vs 3 point argument, especially when you consider the ambiguity of the 2 point landing (I mean is the tailwheel one of the points?) was more similar to the description for the number Pi (π).

Being an irrational number, my landings as represented by a decimal somewhere between 1 and 3 points, cannot be expressed exactly as a ratio of any two integers. Consequently, its decimal representation never ends and never settles into a permanent repeating pattern. The digits appear to be randomly distributed, although no proof of this has yet been discovered.

Re: 2 point vs. 3 point landings

Had a couple pics / notes to put in the 'where did you fly today' spread... but then this thread came to my mind... [-X

For the life of me I've never understood this argument :shock: Like a couple others, I never think to myself what kind of landing I'm going to do, unless I'm on some kind of check ride...

The concept just doesn't compute with me? After all, all I'm really interested in is landing... And since our airplanes make better flyers, than drivers, I try my best to do it as slow, and short as practicable... You know.. crash as slow as you can, and all...

Anyways, back to the 'points' thing... Seems to me that cross wind 101, and simple student pilot knowledge dictates that 99 % of all of your landings really need to be 'one pointers'... And besides being the 'correct' way to land, I'll bet dollars to doughnuts that the next time you land anything, if you strive to exaggerate the upwind wheel just a touch, you will find out that your tendency to bounce will be far less than landing flat!

Oh, and BTW, a quick glance at this pic from a couple hours ago (and the 'frosting' on my tire) will reveal a couple things;
A) which way the wind was coming from, and..
B) even a piggish 2up cub driven by a hamfisted yokel, can be landed in a couple cub lengths or so when 'one pointed'. If you can honestly 3 point shorter than that, my hats off to you, but at this state in my game, getting back out is far more worrisome than getting down :wink:

disclaimer; upstream landing and 15mph quartering downstream wind...

Image

Actaully was on my way to work and kept getting obscenely cool phone pix from a couple Texan cub owners who just kept rubbing it in with their sweet cubs :twisted: Consequently I just had to grab Moma on the way and burn some avgas before the evening work... No matter... this time of year is slow for me. Actually had to fire up the Thrush for a whopping 6.5 acres :evil: Even got back before the moon was up.
This pic was actually from yesterday, but the start was within minutes of tonights;

Well this is for the tailwheel twins out there!!
Anyone ever see or land a Beech18 ,C46 ,DC3, 3 point?? :?:


I have a DC3, and have NEVER landed it 3 pt. and never known anyone who has.

I hope I can be you when I grow up rob. \:D/
Awesome pics man!
So I guess you 3 pointed? How fast were you on final? :P

37.795mph and a half..ish

Grow up? why do I gotta be the grown up one? :lol: :lol: :lol:


Come to think of it, pretty sure Coleen regularly reminds me how much I need to grow up :twisted:

I'd say that's a pretty valid exception.

Yup. I've been sitting on my hands because I can't for the life of me remember which plane it is. But I know I've read about a few that you must *only* three point because of prop clearance. Apparently you took off the same way. Accelerate with all three wheels on the ground until you start flying, then pitch for a more "normal" attitude.

There is a story here. I can imagine it is funny too.

Re: 2 point vs. 3 point landings

The great thing about ski flying is getting to see just where and how you touched down. This would qualify as a three point landing I believe, going by the tracks. Looks like I had a little extra speed here to get that bounce, but I sure cut it close on my touchdown spot, just right. About a 20% grade here, and that brush was 3 to 4' high. Then I powered back up onto the mains to maintain some speed to keep my momentum up. When I get back on the Airstreaks in the summer, I always miss this forensic capability that the snow provides. 8) Image

Unless the prop has been molested, a Thrush with a geared 1340 will be 3 pointed. But as a general rule, Thrush are so docile that they don't care which way you land them (provided adequate ground clearance). While they frequently operate off dirt, I doubt we'll see any on ridge tops or sand bars... So I think in this case again, the OP's statement of 'land it how it's most comfortable' fits perfect.

FWIW;
if you are 5'6" and have average proportions, the hopper of a 510 Thrush will be higher than your line of sight when sitting 3 pt...
in fact,it will be almost as high as the top of your head.
if you are operating off a typical ag strip, the pavement (if you are that lucky) will end just outside the span of your main wheels, so there will be no such thing as an 'S' turn.
and.... most of the time, your only reason for landing, will be to pick up the next load, so doing it slow may not be your highest priority... fast 3 points suck...

One of our pilot/mechanics owns a DC3. It has the gear door mods, but other wise I *think* it is a stock bird. While I have no experience landing it, his experience is that you can land it 3 point, but it wouldn't be the wisest, and he does not. I am almost certain he 3 pts. everything else. There is another 'older wiser' ag operator in our valley who is also a pretty firm 3 pointer. He also wheels the birds that work better wheeled. He has more warbirds and cool toys than a mere mortal should be allowed! :twisted: It is unlikely that in todays world I will ever achieve the experience level of either of these gents, consequently I listen to all they have to offer, and then use the tools that adapt well to my missions or flying preferences.

Take care, Rob

Re: 2 point vs. 3 point landings

Two Pawnees can still keep up with any 600hp radial, but they have to work close to the field. That means satellite fields, roads, and pastures. Both slowness and good visibility are necessary in those landing zones. Both radials and Pawnees are about gone now. Sad.

Looks to me like a 3- 2-almost a 3rd 2, then set the tail wheel down

Bitchin landing know matter how you did it!! Glad your out Playin in the Snow!!
