And generally a stupid stunt, IMO.

Actually a graduate level practice often used in some operations where unimproved surfaces are involved. Common in Alaska. Generally not necessary. I have used this practice to reduce wear and tear on the tailwheel and fuselage over rough terrain where tailwheel steering does no service. It is a tool that a tailwheel pilot should have in their toolbag. You may not use the tool but it is a good tool. Doug

I guess some folks haven't considered/seen engines/props damaged by doing it. (And I'd ask, "What...fuselage wear and tear?")
If the fuselage is being injured by taxying, then it's being taxied too fast, or it should be towed. (I'm thinking lower-48 ops. AK ops are simply not "normal" enough to promote taxying habits that are dangerous to the airplanes and also hazardous to operators/bystanders. I don't buy into the theory that just because some people do or get-away with something in Alaska that it must be a good procedure which others/wannabees simply must accept/and admire, as if they also should aspire "to be cool.")
Yes, (before it's asked) I've done it. No, it's not hard. However it introduces unnecessary risk to self and others. It is not cautious or conservative operation. It probably meets the definition of "excessive speed during taxi" and is therefore likely categorized as "careless and/or reckless operation" if anything goes awry.
But I realize the "cool" factor simply cannot be resisted by some folks, many of whom are eager, yet possess borderline skillsets, so I felt compelled to bring up these points.

It's something I've never tried as my Scottish heritage would never allow me to have such an affect to the bottom line should I screw up.
A fellow worker had a great story that when told by him, had many a aviator busting a gut. The short version, he was an apprentice assisting in an super cub's engine rebuild. They flew to a small airport to return the completed aircraft to the owners. When they taxied up to the apron the entire family was there to see their pride and joy. The pilot decided to put on a show and raised the tail and turned 180 but unfortunately the prop buried itself into the ground and the engine immediately came to a halt. My friend said at the time he tried to sink into the floor but in a super cub there's really no place to hide.
I'm sure if you know what you doing you probably won't do much harm, whereas I wouldn't even give it a thought, as I screw up almost too much even for myself :oops:

Go to 1:14 into this video for a nice tail up 180 degree turnabout on the ground. http://www.vid4fun.com/video_player/index.php?vid=103

I do tail high turns all the time. Oh wait I'm in a helicopter when I do them. Sorry wrong forum. :|

I can imagine that at some point I could feel so connected and in control of an aircraft with the right braking, engine power balance that I would do that. In fact I could see it become so routine that I do it even when not necessary. Kind of like wheel landing on a dead calm day on a 10000 ft manicured firm Bentgrass runway.

However I have never had an aircraft that I feel I could safely do it to the extremes in the popular videos and don't expect I will. I also don't expect I'll ever really need to do it to the point it is worth the risk to the prop and engine.

We all have different risk / reward levels. I don't have a desire to do tail up turns in an airplane so the risk is way to high for me. But I'll do them all day long in a helicopter without thought that some folk don't even want to sit in. :?

Really? I do wheel landings all the time on 2400 feet; crosswind or not. So much so that I have trouble with three pointers :roll:

As far as tail up taxi: I wish I had enough power to consider them an option.

I bet this Skywagon Pilot wishes he hadn't done the tail up taxi.

I can appreciate there being a time and place for such a skill but...

I wasn't going to post a reply because it usually upsets the individuals advocating the learning and practice of such "skills". but as one who has to pay for 180 insurance, I can only hope that you and all others are self insured, as it directly effects the bottom line of my premium bill. And as far as using a tail up taxi on rough surfaces, if the surface is rough enough to damage the tail, what make you think you won't stub a toe (main wheel) and put the airplane on its nose.

Just my 2 cents worth, Tim

Is that to say that 180 pilots are more careless than 170 pilots? 8O

I am not sure this practice is all that common here in Alaska though we have probably all done it a time or two when stuck in the mud and we need to move one wheel first then the other. But just because we have done it doesn't make it smart.

You have to remember that Murphy's Law is wrong. We can do very risky or stupid stuff and frequently get away with it but don't draw the wrong conclusion that you weren't stupid and or it wasn't risky.

I've used this technique once to get a flat tailwheel back to the ramp, but one must use a lot of brake and/or speed to get the tail up and then lots of power to maintain it unless you raise the tail dangerously high. Also remember, rag/tube taildraggers are a lot lighter on the tail than most metal airframes. IMHO it is a less risky maneuver with those types of aircraft, but not usually needed either way. Either way, I don't make a habit of doing it in any aircraft.

I tried the tail up taxi thing in our 52 B once and it was pretty uncomfortable to do. The tongue lashing I got from my father who happened to drive up as I was taxiing by the FBO, though unpleasant was only a small part of my reasoning to discontinue further attempts in our airplane.

The genesis of that bright idea came from doing it in a 1954 Super Cub that I flew frequently. It was pretty fun in that airplane, but there were other cavalier displays of (poor) airmanship (I frequently had trouble remembering that my name wasn't spelled K-y-l-e F-r-a-n-k-l-i-n) in the Super Cub that I wasn't interested in replicating in our baby. Though getting yelled at was he worst of the consequences of my attempt in the 170, in hindsight, had I known how much it sucked, I wouldn't have attempted it in the first place.

My pops did this once while I was in the plane (he had to expedite a taxi actoss a runway) and he used all 40 deg of flaps...the tail came right up compared to no flaps.
