Pat, << Thud could not be got out of a flat spin. Standard drill was to take your hands and feet off, and wait >> The IAC (International Aerobatics Club) division of EAA has developed a "universal" recovery technique for all types of spins (conventional, inverted, oscillatory, etc). In brief: Power Off Hands Off Opposite Rudder (Smoothly recover as rotation ends) Haven't done any spin testing in a while so don't know how this compares to "optimum" methods (which can be different for different types of spins). Enjoy your l'arning.

I am only retailing what a pilot said happened to him in Vietnam in a series on TV called `Dogfight`. It reconstructs real actions, with pretty good computer graphics, interspersed with commentary by the pilots involved. I don`t think it mentioned how much height was needed for the unaided recovery to take place. I was taught `stick forward and opposite rudder` and I am too old to learn a new technique. As the chances of me flying a Thud are not good so I dont think I will worry about it.

BTW in your 'Summer School' -- are you instructor or student ?>> Hi Russ, very funny. Definitely a student studying `Noel Coward` and `Musical Composition` (unrelated courses). In previous years I have `done` Water Colour Painting` `The History of the Third Reich`(the whole class decided that if we were German in 1935 we would have voted for Hitler) `Musical Improvisation` Wendy is `doing` Photograph Manipulation by Computer` amnd learning to play Croquet. Grandchildren are canoeing, abseiling, horse riding, shooting, raft building. Its a great holiday as we just feed the kids breakfast and they disappear with their instructors until the next mealtime. Then we feed `em and throw `em back. I bet you are glad you asked. Leaving this afternoon.

Side slipping is nice for cross wind landings.>> Hi Jack, aven`t really got into very strong cross wing landings in the Kolb yet so I have that to come. In the Challenger I almost always side slipped into a landing. I just liked the precision of landing on a pre chosen spot. <> Oh dear, I hadn`t realised my throwaway remark would generate such interest. See the detail in my reply to Russ. Its a bit of a b****r in fact as the weather has come good for almost the first time this summer and I should be flying, not `larnin`. Still, I flew twice yesterday and took Wendy up for the first time the day before. I think that is the first time I have flown two days in succesion this summer. Return from school next Saturday and there is a very big fly- in about 60 miles away on Sunday so I hope to make that. The fly-in is a re-run of a previous date which had to be cancelled, for the first time in 29 years, because the field was flooded. Fingers crossed.

Kolbers, I have been lurking here for a while since I built an original Firestar back in the mid 80's and have been thinking about getting another one. I don't think I have had as much fun in any airplane since. I am moved to contribute on the subject of spins, having flown many airplanes from Hummers to Kolbs to the F-106, A-10 and F/A-18. I can tell you that high performance jets, particularly those with strongly swept wings and big engines in the tail, have entirely different spin characteristics than light airplanes. For example, the mass distribution along the length of the fuselage can result in strong inertial coupling that the flight controls simply cannot overcome, or the axis of rotation may not be inside the length of the airplane resulting in very high G forces that can incapacitate the pilot. In other cases like the F-106 the plane would eventually recover but the altitude required could be way more than what was available - like 30,000 feet. The Air Force required all of the pilots who flew the T-37 to practice spins and had a very effective spin recovery technique. It simply does not work in the higher performance airplanes. Also note that the IAC "universal spin recovery" probably works fine for straight wing light airplanes, but even it is a compromise. There was a great article about 15 years ago detailing the development of that technique indicating that one of its specific goals was to deal with disorientation and resulting incorrect control inputs. By teaching a compromise that would always work it was better than trying to teach how to recognize the confusing differences between variations of upright and inverted oscillating spins. In other words, some recovery power that would be available if the controls were in the optimum position was sacrificed to reduce the potential of the wrong inputs being made. Fortunately Kolbs are sweet flying airplanes that will take care of you if you take care of them. Fly Safely Jim **************Get fantasy football with free live scoring.

Seemed very conventional to me, wing dropped and it'd try to flip over onto its back into a spin. Recovery was just letting go of the back pressure on the stick an applying opposite rudder and it was flying again and going back to a level attitude. Ailerons still kind of work even in a full stall.... Very no-surprise and docile. No idea about a developed spin tho...

Sorry Guys, just couldn't hold back do not archive Steven ________________________________ Message 16 ____________________________________ Time: 08:30:21 PM PST US Subject: Kolb-List: Re: Spin Recovery (Weight and Balance?) From: "Dave Bigelow" Jim's notes on spin recovery of high performance fighters brings back many memories. One of the famous Air Force aircraft of its time was the F-101. In a very high angle of attack situation, the T tail could become "blanked" by the wing's airflow, and it would pitch up into what was called a "departure". Not sure exactly why this term was used, but it was usually the pre-cursor to the pilot "departing" the aircraft via ejection seat. One of the hazards of flying sail planes in mountain wave conditions is the clouds filling in below and trapping you above an overcast. Some Schweitzer 1-26 pilots advocate putting the glider into a spin and spinning through the overcast. They recover after popping through cloud base. Sounds pretty "iffy" but seems better than losing control in the clouds and suffering a structural failure. The idea is that a spin is self limiting in airspeed and G loads. I've spun the 1-26 a number of times, and it's a pretty straight forward entry and recovery. A number of years back (in my younger and more foolish days), I was over a scattered to broken cloud deck with bases at 4,000 feet. A 1-26 is easily recovered in about 500 feet, so I decided to give the spin through the clouds plan a try. I entered the spin at about 7,000 feet, stabilized with pro-spin controls (full rudder in the direction of rotation, and full back stick), and entered the clouds. It was horribly disorienting, and I nearly got sick. It seemed to take forever to get through that 2,000 foot thick cloud, and the whole time felt like death was imminent. It was a great relief to pop out of the cloud and recover. Haven't repeated that foolishness since!
