Touchdown! Greaser!
Student practicing solo stalls "early" in his training.
Did you get a lot of wing drops with your power-on stalls? The ball-centered skid will do that.When I was practicing stalls by myself, I could hear my CFI: "keep the f... ball centered!"
Your instructor wanted the ball centered, too, didn’t he?I was always wretched awful at getting into a power on stall situation. I kept dropping a wing.
He probably had just enough training to do it when he was prepared, not when he was unprepared.Also, I notice a hint of poor spin recovery by this guy (I’m a PARE guy)... in the recovery I see the throttle (via tach) remains full.
No, but my CFI made me practice a few power-on stalls with leveling the wings with ailerons so I could see the difference.Did you get a lot of wing drops with your power-on stalls? The ball-centered skid will do that.
I need an explanation of "1 wing stalled more than the other" Like there is a measurement of stallishness?
Some of them won't, after two or three turns. Cessna issued a POH supplement on it. They can go flat and require brisk forward elevator immediately after full opposite rudder. The modified POH said this:Never came close to spinning my Cessna 150. Heck, even if it did, you just take your hands off everything and the airplane will come out of it all by itself.
More than that. Watch the copilot's control wheel when he gets the wing drops. A bunch of remedial training needed. A 150 will often forgive that. The Champ he goes and buys after he gets his license won't.Also, I notice a hint of poor spin recovery by this guy (I’m a PARE guy)... in the recovery I see the throttle (via tach) remains full.

As a cfi I don’t think he should be flying solo. That level of incompetence shouldn’t be alone in an airplane.
Ball centered skid???
I guess technically it’s a slip, but the effect is the same.Ball centered skid???
I had 150s resist my trying to spin them in certain scenarios such as a skidding descending turn. The Champ never resisted. Flicked over right away.Sadly, a lost opportunity.
A properly rigged 150 is one of the most fun training planes to spin.
.......Also “cross control” stalls so they could also see the dynamics of a skidding stall......

The downward blade produces more thrust, so much like a multi engine airplane on one engine, zero side slip isn’t with the ball centered. If a yaw string worked on the windshield of a single, it’d be easy to demonstrate.
The plane wants to turn left...you compensate with right rudder, so you have both the front and back of the airplane being pushed equally to the left. No turn, but side slip.I dunno about that. The left turning tendency from P factor will make the plane want to turn to the left. But you could be perfectly coordinated while that was happening. The wings and the ball have no sense that you are flying a slightly curved path over the ground. I think

read up on multiengine training.
The ball is not a yaw instrument...it only shows slip or skid under a very specific set of circumstances, which are not met with the asymmetric thrust of single prop at high power and high aircraft AOA, or a twin on one engine. The a couple degrees bank in a twin, with the ball out of center, is zero side slip.Yeah. Got that. If you want to stay straight ahead over the ground. But, assuming the inclinometer is accurate, if the ball is centered, you are neither slipping or skidding. Your just flying a curved path over the ground. I was thinking about multi engine. It's been a long time since I've done that. There's the bank the airplane into the good engine thing. I think airplanes have to certified with Vmc established with no more than 5 degrees bank. And yeah, if you do that you're likely be in a skid or slip. But if you are, the ball ain't gonna be centered. I think.

it has nothing to do with “over the ground”...it’s all relative wind, which the ball can’t sense.
Wouldn't that be the dynamics of a 'slipping' stall
I haven’t watched it, but this video seems to be titled appropriate to the discussion...I gotta get out my toy airplanes and experiment. Do you know of any good videos or websites explaining all this?
Anyone counting speed up by 5s in a 150 has their eyes down way too much! Would someone get this guy some TW training! ?
Were you my CFI? I remember mine yelling get your feet on the floor during a power on stall and me not thinking about what was about to happen. That 150 broke and flipped right over on its back. Scared the ever living hell out of me.That puzzled me as well. A skid is when the bank is insufficient for the rate of turn. So far as know, that condition will always move the ball to the outside of the turn.
Early in my training I got a pretty good scare in a 150. I was doing a departure stall, and must not have had enough right rudder. I think I also accidentally had flaps down. In any case, I got a hard roll to the left with the nose dropping - what I now consider an “imminent spin”. I got the nose down and must have used enough rudder and stopped it at around 1/4 turn.
It led me to later make sure all my students got to see that scenario, intentionally doing some power on stalls without any right rudder, and then have them recover from the “break” that followed. Also “cross control” stalls so they could also see the dynamics of a skidding stall. It may have been mentioned already, but the typical “not enough right rudder” stall in a departure stall is a stall from a slip - too much bank for the rate of turn, which is usually zero just prior to the break.
try it with people in the back seat to get the CG off the forward limit.Power off, yoke to his chest, he just sat there with the ball in the center, the plane went on to stall, recover, stall, recover rinse repeat all in its own sinking 1500 fpm.
