The reason for the A (ailerons) of PARE is that some pilots, faced with an inadvertent spin, will tend to use the ailerons, just like a good many pilots, who do a stall which results in a wing dropping, will use the ailerons to lift the wing. While using the ailerons to recover from a wing-dropped stall isn't necessarily awful (still not best practice), using them while in a spin will often aggravate the spin and make spin recovery very difficult if not impossible.
So while an intentional, practiced spin is rarely initiated with anything but neutral aileron, it's a fact that inexperienced pilots, or pilots with no spin training, can really muck up a spin recovery if they try to stop the rotation with any aileron at all. A of PARE really means "lock the ailerons absolutely neutral!!!!" It makes a huge difference.
I disagree with letting go to recover from a spin. Yeah, many airplanes will recover, but it takes a whole lot of altitude for that to happen. It's much better to do it right. If the POH doesn't cover the technique for that airplane, use PARE. But don't wait until you're in a spin to wonder, "how do I get out of this?" Get some spin recovery training first.
Overall, that's one of the FAA's better training videos. Some of them leave me scratching my head, asking "what were they thinking, to put that crap into a video?" But not this one.
Let me describe an event that relates to this video. The "student" was the same student I've described who thought IMC flight wasn't all that difficult, until I let him lose control in the clouds. But by the time this later event came along, he was a private pilot, with perhaps 80 hours flight time, and he wanted to be checked out in a 182. So I told him to study the manual, then bring along his wife and perhaps another person, and we'd do it. But when he showed up, he was alone, and he hadn't studied the manual--his excuse was (as I've heard many others mis-believe), "Aw, it's really just a wider 172--you can just show me the differences".
But as I like to say, a 182 is not just a fat 172; it's a different airplane. So I told him we weren't going to fly, because it would be a waste of time. Go home, study the manual, bring along someone for the back seat, and then we'll fly. He was a bit miffed, but I think he knew I was right--but remember, this guy was a bit boneheaded--brilliant, but stubborn.
The next day, he arrived for our rescheduled flight. Overnight, he had literally memorized the manual, and he had brought his wife and a friend of hers as "ballast". When I asked him questions about the airplane, for instance in response to "from cruise flight, how would you go from 8500' to 10,500'?", he would say something like, "referring to section 4, at page 4-15, and I would raise the nose to slow the airplane to 95 knots, then increase rpm to 2450. At 8500', I would already have the throttle all the way in." He had the exact book answers for every question I asked, so we loaded up.
After take off, I recall that we just flew around for a little while, so that he could become accustomed to the heavier controls. Then I told him to climb to 11,000', so that we could do some airwork, various kinds of stalls, steep turns, and the like.
During his initial training in the 172, one of the things I had taught him, to emphasize rudder control and effectiveness, was walking the rudder while in a full stall (falling leaf); in a normal 172, that can be done power off or power on, and he could do that extremely well. I had also taught him spins and spin recovery, and he was pretty proficient at that as well.
After we'd done some of the airwork in the 182, I mentioned that although he could walk the rudder power off in a 182, don't try it power on. He asked why, and I said, "Because nobody can do it--it's impossible." He said, "I bet I can do it!" Like a dummy, and thinking that it would be something he'd try on his own if I didn't let him prove that he was wrong with me aboard, I replied, "OK, smart guy, try it and you'll see."
A power on stall in a 182 with a somewhat aft CG (the 2 women) has an amazingly steep deck angle. When it stalled, it hung there for a moment and then started to fall off to the right. He caught it, and it oscillated to the left. Again he caught it, and it oscillated back to the right. This time, when he caught it and it oscillated to the left, it flipped over into a full power spin, and he froze! He did nothing--he still had full left rudder in, the yoke full back, and full power on. Ol' Dummy here attempted to calmly talk him out of it: "Steve, pull off the power, opposite rudder, stop the spin." I think I said that twice before I realized that he wasn't likely to do anything. I said, "I've got the airplane", and still he didn't respond. I shouted, "Let go of the controls!" Still he hung on.
Now it was getting critical. The women were screaming, the airplane was losing altitude. Finally I hit his arms so hard with my left arm to get him off the yoke that I had large bruises for several days afterwards. It took all my right leg's strength to push the rudder in. When the spin stopped, I leveled the airplane off less than a thousand feet above the ground. Fortunately, we were over the Big Hollow west of Laramie, but we were down to about 8000' MSL--only about 700' above the airport's elevation, but the Big Hollow dips down roughly 200' lower.
As we leveled off, he snapped out of it. He acted surprised that I was flying the airplane. We flew back to the airport, and as we slowed after landing, his wife asked, "Can you stop the airplane here--I want out!" So we stopped on the taxiway, I shut down the engine, the women got out, and we taxied back to the tie-downs. I wrote in his logbook something like, "182 checkout not completed--not authorized to solo 182, unsatisfactory stall series."
I don't know if anyone else ever checked him out in the 182, but I never flew with him again, and I let all the other instructors know about the experience.
Lesson learned--when a student doesn't immediately respond to a command, take over. Don't wait.
To answer your specific question, Motoadve, I can only tell you my own experience. Both a 172 and 182 are difficult to spin, but they both recover pretty quickly. A 172 in the utility category is authorized to be spun intentionally, and it will recover in slightly less than half a turn, even after a 2 or 3 turn spin. A 152 will similarly recover in less than half a turn--note that after the 3rd turn in a multi turn spin, it tends to oscillate and wind up tighter for a couple turns, which is interesting to say the least if you're not expecting it. A 182 is not authorized to be spun intentionally, but from that one experience above, I know that it will recover in about 3/4 of a turn after being in a spin for approximately 3-4 turns. All 3 POHs use words that describe the PARE technique. A Decathlon can be made to recover in less than a quarter turn, if the stick is pushed forward before the turning is stopped with rudder--in other words, not waiting until the turning stops. My aerobatics instructor showed me that. Those are the only airplanes I've spun. All certificated singles must be able to be recovered from a spin within one turn, using "standard spin recovery techniques", which is basically PARE.
