Ivan's suggestions are the best comprehensive outline of how to use the aircraft.
I will add an addendum to Ivan's notes for the Spit IIA:
It is not all clear sailing.
At higher altitudes, you cannot run full boost without an issue, and do not expect that you can run 105 degrees C oil temperatures without engine damage.
Over 10,000 ft you need to keep your oil temperatures to 95 C or below, I realize that is tough to do, but if you let it creep over that, the chances of catastrophic damage are inevitable. Yes, this is a lower temp than what the Merlin XII guidelines allowed, but that's the inaccuracies of the game.
Also, running full throttle/boost over 15,000, even though your boost meter is not showing the engine attaining a very high number, is going to kill your engine if you do it for any more than a 10-15 seconds at a time. Heat rises extremely fast.
For the Spit IIA, practical settings which you can leave the engine at when continuously climbing and keep it quite cool.
0-5000 ft: 2800 rpm and +6 boost full rad, climb speed 160 mph gives approx. 85 C
5-6000 ft: 2800 rpm and +4 boost full rad, climb speed 160 mph gives approx. 87 C
10-15,000 ft 2700 rpm and +3 boost full rad, climb speed 150 mph gives approx. 90 C
15-20,000 ft 2700 rpm and +1-2 boost full rad, climb speed 150 mph gives approx. 93 C
At higher alts, this means you are climbing quite slowly, but gives you the reserve of temperature you need if you get into a fight.
Once you level out, try to reduce the rpms and boost as much as possible at high alt, to drop the temps to 90 C, it's tough to get it below that. It's also possible to reduce rad opening to 50% or below, depending on the altitude you are at, below 10,000 ft, at lower rpm's and boost, you can close the rad down quite a bit to increase cruising speed and still keep your temps around 85 C.
Once you get into combat, you can exceed the above guidelines for rpm and boost, especially if you are diving, going 3000 rpm and +9 boost below 10,000 ft is fine, I tend to go no higher than 2800 over 10,000, but whatever you do, you need to keep a close eye on the gauges, beware of the oil temperatures going over 95 C, especially up high, the engine seems to tolerate higher temps better down low. And stay away from full throttle/boost over 15,000 unless its an emergency and keep use to short periods.
