Wings,
Even one notch of flap could produce a significant nose-down trim change at the speed at which it would have been flying.
True, but that's not what R4H was rightly describing. With 23 degrees flap selected throughout the manoeuvre in question, there would be no 'significant' nose down trim change.
An admirable concise post from a very experienced Hunter pilot and QFI
If I recall correctly, use of 23 flap in ACM caused an initial nose-down trim change, which in the environment of dynamic ACM was easily overcome by a firm elevator movement. The effect of 23 flap gave an increased turn rate, which was advantageous in getting to a sight-on solution, but the increased drag meant that it was only a temporary advantage?
Whereas flying certain manoeuvres with 23 flap was entirely normal for formation aerobatic teams.
