Of course the simple answer was given very early on. Watch attitude, moniter airspeed, stay co-ordinated and all will be well. There ends the thread!

But no! ... the great thing about these forums is the further debate, and the lessons you can learn from them. It's all very well to then pipe up, complain and say that we're all just going to confuse the poor student, but what does that achieve? We could start a new thread, but then the momentum is lost. Nope, I like the way these things blossom. Hopefully even a student pilot will soon get the basic answer to his/her question, but will often learn more by lstening to the debate of those with more experience.

I'm not sure if this
Talk of Angle-of-Attack and loading the wings is much more "right-on Piloty" and in keeping with "grass roots flying", but not very helpful to a low-hours pilot IMHO.
was aimed at my post, but I kind of think it was. If it was, it missed the point. I like Miserlou, started off flying gliders. The over ruddered turn onto finals was a known killer, and therefore well banked (but co-ordinated) turns were drummed into us. Whilst gliders are very different beasts to most light aircraft the principals are the same. When scratching for lift in very tight turns and nibbling the stall buffet, you do learn a lot about the effect of bank and g on stalling. Again, I realise gliders are much more benign than most light aircraft, but again ... the principals are the same!

Bank angle does increase stall speed, higher G does increase stall speed ... but niether cause spins in any greater way than any other stall. If co-ordinated a quick nudge forward will (usually) get the wing biting again. Some aeroplane flik ... but usually there has to be some rudder influence to cause this.

The above may sound Gung Ho .. but that is not the intention. I simply believe .... no, I KNOW, that a skidding turn onto finals is far far more likely to result in a spin than a well banked co-ordinated turn.

Obviously it's far better to judge it all correctly to make sure you roll out nicely on the centre line from a gentle well judged turn, or go around if the picture looks wrong. But in the real world we tend to try and correct our mistakes even if it's not always the wisest thing to do. But if you are to try and correct an over cooked final turn ... use a well banked turn ... not an over ruddered one !
