Crump you said :

"It is and I did not ask you to post it because of some abnormality. I asked you to post it because it specifically warns the pilot NOT to fly in the buffet zone and even to ease off the stick by pushing it forward."

Guess what you do when you go past the Buzz and get into the buffet ... you ease the back pressure off to get back into the Buzz .... Ideally the very first hint of it. Thats the art of max performance turning.

Then in response to my statement:

"Max performance turning is done "On the Buzz". A standard exercise is to do this whilst airspeed and G are changing whilst holding the aeroplane on the Buzz throughout without reference to AOA instrumentation etc ... just by feel."

You said:
"Only in modern FBW...."

Ok you are really off the plot in this response and thats just wrong.
I learnt to fly on the "Buzz" in a Winjeel and then on MB326H aircraft. Both Cable and or Manual push rod controls no Hydraulics or FBW. I also do it regularly in a YAK52. Whether you like it or not thats the way you practically get max turn performance in conventional straight wing aircraft. You want to get pretty close to Clmax to do achieve that, without an AOA gauge the first onset or the buzz IS the cue that is used. I am not the only one posting here to that effect.... see RAF_Wingers post.


You then said
"Aerodynamic buffeting will not increase your turn performance,it will degrade it."
No argument I didnt say that.... but see above response.....

You then said;
"And that "buffet" has nothing to do with the aerodynamics of the aircraft. It is a programed stick shaker placed there by the engineers to let the pilot know he is nearing stall speed and is "On the Buzz" at the point the stability and control engineers put it."

Sorry mate but with respect thats just total crap, and shows you dont really know what you are talking about. The fighters I have flown operationally the Mirage III and F18 Buffet like hell as soon as you start to get some Alpha on the jet. The Mirage III is even in buffet in the circuit ! ..... nature of the beast..... neither type has a Stick shaker or Stick Pusher system

As to Stick shakers I have flown 2 types that were equipped with these ... both commercial transports that required them certification wise both conventional Hydro mechanical controls.

Now I dont know your background Crummp but if you had some practical experience in realitvely high performance straight wing aerobatic aircraft and had been taught how to get the maximum out of it you wouldnt be saying the things you are.
