Maybe those planes get closer than one would expect... maybe that is why
the wet blankets are complaining :-)
OK, on a serious note what Bob said makes sense to me.. and easier

Surely the planes are at infinity or beyond? So why focus at all? Choose your
focal length and aperture, set it manually to infinity focus, or the hyperfocal
distance, and leave it. Or am I missing something?

I have never found a single solution that works all of the time. I would try
A-9 AF-S set up in the center, also manual. I agree with Godfrey’s suggestion
of planning ahead. Pre-focus so that things are close to in focus, wait until
the subject is close to in focus and within the 9 selected points.

The South African Aerobatic Championships is currently on in Phalaborwa with plenty
of Photographic opportunities. I've tried everything but just don't seem to be able
to focus on fast moving aircraft at height. I get close with MF but AF.S AF.C are
hopeless. Perhaps someone can enlighten me? Perhaps screw drive is too slow? I've
tried the K5 with the HD 55-300 @ 300mm & the Sigma 170-500 DG @ 500mm. I can
focus just fine on the quarter moon!
The Airfield is less than 1Km from my house! About 40 planes are taking part.
The last event like this in Phalaborwa was about 25years ago so this is quite
something. Of course there are several wet blankets complaining about the noise.
