...there is a chance that I am a lousy pilot, don't know how to fly my Maule, something aerodynamically is wrong with my airplane: or all three. But I find it impossible to make wheel landings in my M-5 without carrying a higher approach speed than I do with a typical approach culminating in a three point landing.

I typically approach at 60 mph indicated, carrying power for a three point landing. If I want to make a spot landing for the shortest rollout I will approach at 55 mph and carry a bit of power right to the touchdown. Such approach speed requires a pitch attitude which results in a very tail low attitude in which, if I am not careful, the tailwheel will touch before the main gear. Something that has occurred on a few occassions. Now when approaching at 55/60 mph for an intended three point landing...I have "accidently" had the mains touch first with the tailwheel an inch or two off of the runway and 2 or 3 seconds before the tailwheel touched down. Such a landing is always a surprise, unintended, very sweet and....I suppose it could be considered a wheel landing. But what is the point of a wheel landing that has the mains on a second or two before the tailwheel anyhow?

If I want to make a wheel landing I must fly faster....at least 70 mph indicated. Otherwise the tail low attitude is as indicated above and I end up with a three pointer any how.

Now if I want to make a three pointer with an approach speed of 70 ish indicated I can do that. Having stated that I can make a wheel landing if I approach at 70 ish....then one could argue that I do not have to fly any faster for a wheel landing than a three point landing. However in my airplane if I carry the higher airspeed and make a three point I have to float down the runway and bleed of the airspeed. Otherwise a higher speed, three point touchdown, results in an airplane that doesn't want to quit flying and so we skip and bounce along a bit until the excess lift is killed off.

Now Mr. Maule told me that there NEVER is a reason to make a wheel landing in a Maule. One would assume that he is talking about a hard surface runway or at least a smooth runway surface. Well...he may be right under those conditions and as long as one operates within the demonstrated cross wind component limits. But my experience has demonstrated over and over that if the cross wind component is say 20 or 25 kts. and/or there are very strong gusty winds....my airplane better be landed on the mains first and it better be flown at speed higher than one would normally use for a three point landing. I've done it both ways many times. The only time I darn near ground looped or ran off the runway was when I made a three point landing with a 20 kt. cross wind component and gusts. On that very occassion I was intentionaly practicing landing under those conditions on a paved runway. I made 10 or 12 such landings that day. Every wheel landing was a handful but fully controllable. After two three point landings under those conditions.... which resulted in a couple of wild roll outs.....I decided that Mr. Maule was full of baloney. You would be correct to say that the airplane was being operated beyond it's intended limits. I would plead guilty but add that most of us have found ourselves in such situations unintentionally. In anticipation of such I have always wanted to know the limits of my capability and that of my airplane....just in case.

I flew various models of the Twin Beech on mail runs for hundreds of hours. 100% of the Twin Beech pilots that I ever met made wheel landings. One had to carry extra speed . Otherwise the pitch attitude would result in tail low attitude and a three point landing. Not a good idea in that airplane. Point being....like in my Maule....one had to carry higher airspeed in the Beech in order to make a wheel landing and not an unintended and undesirable three point landing.

If one reads the history of Continental Airlines going back to late 30s and early 40s one will find that there was a raging battle, among their pilots, over how to land the DC-3. The Chicago based pilots always made wheel landings. The Houston based pilots all made three point landings. The arguments continued until the Houston based pilots started flying routes into the Windy City of Chicago. Not long after that....the mandatory standard became...wheel landings, carrying a bit more speed. Not saying it cannot be done either way. Just saying history indicates one was safer than the other....much like my experience in the Twin Beech.

And....I double dog dare you to make three point landings in a Pitts S-1. Approach speeds are high and three point attempts result in many skips and bounces off of the runway. I only met one pilot who could do it successfully. He was an airshow guy who said that every Pitts pilot he had ever met, including yours truely, found it impossible. Different airplanes. Different results.

I will continue to fly the Maule under various conditions as I have for the past 9 years. But I will also defer to the pros here and accept any criticism or lessons in aerodynamics offered.

Re: Wheel Landing Question

My shortest landings result from very slow, steep approaches, nose high, high rate of descent, and counting on ground effect to cushion the impact, which is three point with heavy braking. What some of you may call a "carrier landing". One technique whether the plane is conventional or nosewheel. Effective when practiced but never comfortable and rarely necessary, and your passengers will not enjoy it. My SOP landings will also use a steeper than average final approach at slightly higher airspeed and terminate with a tail low wheel landing. I never three point except to demonstrate to myself that I can. The average GA pilot flies the final leg too shallow, and that opinion is the result of my own experience with being average. Shallow, flat approaches lead to higher touchdown speeds and poor touchdown spot management. Steeper finals solve most landing technique problems.

Most Valdez guys will counter the steep approach by dragging in low and flat while hanging on the prop, and chop power to plop it on. They practice it and they're good at it, and most of the top competitors have specialized equipment that favors that technique. Go try it coming in over trees in a turbulent crossing wind in your plane. You're far better off being proficient with the steeper approach.

Re: Wheel Landing Question

It makes sense to say the slowest landing is in the three point "attitude". The nose up is just slower. Whether you let the tail wheel touch or not has as much to do with the size of your mains as whether you call that nose high attitude a two wheel or three point or tail low two wheel landing. If the main wheels are smaller, the tail wheel touches at the same time and you can claim its a three point. With those tires it is probably as short as possible. Put on bush wheels, and with them being taller go make the same landing at the same attitude but now taller tires allows the pilot to claim his landing was two point because the tailwheel never touched. The point is with the taller tires the nose can even go higher at touchdown with out touching the tailwheel than it did during the three pointer when the same plane was on smaller tires. For a fair comparison of what is shorter the comparison of two vs three should be done with the same plane on the same tires doing both three point vs two wheel.

The Tundra at twenty five degrees flaps approaches the landing already in a three point attitude when using 8.50 tires. It is self rigged for the three point and to get a two point, takes at touch of power and a release of back pressure (with trim set slightly nose down) or a little forward push to stick the two point, which I prefer for visibility. With bush wheels I would expect it to be like Rob's Maule, where now instead of the tailwheel touching with the mains, I now have the bush wheels touching ground first but tail low. On 8.50's this landing attitude would have gotten a three point.

Oh, and I use the same approach speeds on both two and three point.

Re: Wheel Landing Question

Go to altitude and stall your plane. It won't settle into the three point position. Nose high is only possible with adequate speed above the stall. The value of a slow, steep approach with the nose high is that you can ride the edge of the stall and still have that safety margin of lowering the nose to maintain and control speed.

Re: Wheel Landing Question

This could get ugly: I think Gump spoke to adding half the gust factor to a gusty/crosswind landing, which works beautifully and in that case like he said speed may not be easily controlled to the knot and you've got bigger problems.

A simple formula that stuck with me was this.

Assume your Landing distance is 1000 ft.
1. First number to calculate is: Actual Approach speed / Correct or normal approach speed (i.e.) 80/65 = 1.23
2. Square that number = 1.51
3. Take the two numbers after the decimal point (in this case 51), and that IS your approximate percentage increase in landing distance.

This really does work, and if you're talking about landing in 500-1000 feet, you really need to be on speed.
In this example if you're landing distance is 1000 ft, being 15 kts fast (gross example, i know) takes your landing distance to 1,510 and that is unacceptable.

This only argues against those that say wheel landings are flown at a faster speed.

I AINT CALCULATING THIS CRAP SHORT FINAL. ALL IN THE PRE-FLIGHT PLANNING, OF COURSE.

Re: Wheel Landing Question

There will never be a single answer on this topic as long as planes, weight, CG, pilots, weather and landing zones are different. An inexperienced tailwheel pilot should go up with a good instructor who knows the airplane model, explore the airplane's performance envelope and practice on a variety of landing zones in varying wind conditions.
