I find this subject of rudder/aileron fascinating in England particularly where the set way of teaching and operating light aircraft is set in stone with some people. Any contentious, challenging or interesting views are a threat to the whole meaning of life (which incidentally is 49)
Now, before someone goes off on a tangent like in previous posts, I am not trying to insult anybody, just instigating a healthy discussion as there are clearly different views - which from my analysis mean the same thing. (in general flight)
1. You cannot use the Rudder without some Aileron input.
2. You cannot use the Ailerons without some Rudder input.
3. The rudder has nothing to do with turning the Aircraft,
left aileron =left rudder
right aileron =right rudder
no aileron=no rudder
unless in a side or forward slip

Regarding the Approach;
At an aerodrome like Elstree or on rwy 18 at Cranfield it is always turbulent. The Aeroplane gets tossed around laterally and inexperienced pilots or students tend to over react with the ailerons without rudder to correct this. Now I have observed that this, as well as making the situation worse, also moves the nose side to side (adverse yaw as the inputs are usually too large and quick).

So I advocate using gentle rudder pressure; NOT to pick up a wing, but to prevent further drop and if necessary assisted with
aileron. And I can do this without the ball moving from its centre position which unless someone knows different means co-ordinated flight. The difficulty is judging how much input.

I also teach to lead turns and the rollout from turns with the rudder. NOT bootfulls of rudder, but to start the process with GENTLE rudder pressure assisted with the Ailerons for the bank angle. Then centralise everything once in the turn or when wings level. Again the ball does not move.

DANZ, I like to teach rudder and aileron together from trial lesson onwards so it becomes habit. I found if you leave it until the syllabus dictates it is too late to break the habit of just using the pedals as footrests. The first few lessons are spent just stick and rudder visual attitude flying - and nothing else.

A further point to anyone, do you teach that as well as using the good old right foot in high power low speed situations i.e. take off and climb, that you need to a little left foot when reducing power?

FF, how do you prevent or correct a wing drop at, approaching or during the stall?
I ask this because in this and the last discussion you hint at not using rudder near the stall, which I find odd as the use of aileron at near stalled conditions will surely cause an incipient spin unless the wing is unloaded.

Well, anybody got a ladder so I can get down from my skyscraper height soapbox??
