To be honest, you'll get all sorts of advice, but its what works for you.
Personally, for jets I use AV, not TV, and set the aperture either as 5.6 or sometimes if its very bright a couple of stops smaller.
Evaluative metering works fine, I find the problem with spot is that it exposes for a very dark underside if you plant it wrongly. Thats easy to do with something thats shifting very quickly, and you end up with a very bleached picture.
For props, then I wind down the aperture until I get to about 125th shutter speed. For a prop aircraft thats usually good enough. Helicopters are another matter! Even down at 1/25th second on say a chinook, the rotors will only be blurred in an arc. I've never been brave enough to go lower than that.
All that works for me, and I've been doing airshows since the Mid 80's. Ok, TV may work for others, but both have drawbacks, for example, shutter or aperture not being able to match what you want to use as the opposite value.
Anyway, this is the sort of thing you can end up with doing it the above way.
