Turn to final stalls

[flyguy]

Beautiful day here in the central valley California. Hot weather let up some. Nice; even in the late morning.

Have been doing a thing where I fly often in the local area and pattern lately. Short flights and landing practice several days a week.

Today I decided to do some air work and was practicing stalls and slow flight, 45 degree bank turns and such.

Tried something that I haven't done in some time and likely never exactly this way. I tried to induce a stall from a low airspeed turn by hauling back on the yoke in the turn. My 12D-85 is a bit on the heavy side so it stalls at about 44 statute, or packing a bit of power maybe down to just above 40 or so.

I got it down to 50 with the throttle back and let the nose stabilize in about a 30 degree turn and hauled back on the yoke. The ole girl did a little shutter and flopped her wings around a bit and didn't do much else as I let off on the back pressure. (I was thinking more of an accelerated stall so I didn't hold it back when it didn't happen).

I just wanted to see how badly it would behave with that kind of abuse of the controls, but I wasn't trying to do a routine accelerated stall, which I know is done differently.

Never have been able to get this one to flop out over the top like you can in an Aerobat 150. As I remember you can get the Aerobat to either roll over the top, that is an easy recovery, or out the bottom which can get pretty exciting. All the 12D does is shake. rattle and no roll. Chuckle. I would guess that is a good thing.

Anyway it was a fun flight, much better than going around the pattern and I think I learned a little something more about the plane.

Just to be clear, you DID NOT do this in the pattern, right? ;-)

DC,

My instructor showed me years ago what not to do, which seems to be a lot of the problem with a turn to final, (as the title of this thread is). Take her up and then act like you are doing a base to final with all the correct speeds, etc. Cross control her like you are trying to get lined up with the runway without banking the airplane. Slow her down enough and get enough controls input and she will get your attention. At least mine did.

When I transitioned to my 1st Tcraft (40 years ago) my instructor had me do an accelerated stall just like the Cherokee I got my license in. It snapped over the top and entered a spin. That certainly caught me by surprise but he knew exactly what was going to happen. I've never forgotten that lesson.

As long as you are in generally coordinated flight (i.e. ball centered) you will get just the result you described regardless of bank angle. Now, try leading the turn with some rudder while using the ailerons to avoid too much bank angle. You do need to have some turn rate going to get the full effect. It won't go over the top; it will tuck under quicker than you can say, "Oh sh--t". I think I'm saying the same thing as Marty.

Be sure to have some altitude when you do this.

Yup, Dick. It will get your attention going from benign flight to

Hank,
You mean you aren't supposed to do that as a test on final? Chuckle, just kidding. I was at almost 3,000.

Rather than the crossed control thing, I was just checking to see how it would respond to rough use of the controls in a minimum speed turn. Kind of a "sensitivity to stupid" test. Likely title was not a good choice, but it is indicative of what I was thinking about at the time.

The cross control thing is what I was taught as a precision entry to a spin that is used with a Cessna Aerobat to prevent doing a whipping high G turn if you screw up on your control timing when using the "kick the rudder" method. Only difference is that we used a little power for more of a left bias.

I think we have discussed it here a few times. It will produce a really nifty 180 degree heading reversal in my 12D.

3000 here is 1400 below dirt level...Tim
