4.11 - Engine: Overheat!

On an aircraft with a constant speed prop, you set the rpm with the prop control, and the engine manifold pressure with the throttle.

To get a high manifold pressure you would set a low RPM with a large throttle opening.

Within limits lest you get detonation

A good read if you want to know more about engine management, Manifold pressure etc:

Some very good info here. Thanks for posting!

Mr Treetop64, is there any info about the radiator operations in the game? I mean, temperature limits, minimum, maximum, and for how long permitions, drags, speed limits in open(if any) etc?
I think we have some info about the engine RPM`s, not sure, (best cruise, best economy, best climb, max RPM...) But we dont have any info on the radiator operations. Do you know were i can get some? (not for real wwII aircraft, because i dont fly them, but for the 4.11 version planes. (if they are equal to real life wwII planes, better, we can extract from more sources...

If we should go for the gauges as you said (i agree) we must know limits.

Hope anyone can help, and on RPM´s also. Thanks.

Not sure, but the best way to start getting this sort of info is to find out what kind of engine a particular aircraft type has and do a google search on operating limits for that engine, or you can do a search on FAA Type Certificate Data Sheets. You may have to hunt around a bit on the FAA website, and I doubt if they have anything about old Klimovs or something equally esoteric, but but they do have tons of good information on many engines.

It helps to just get very proficient in two or three types of aircraft in the game, fly in them a lot, and just getting a feel for what works best. Just get in, fly her hard, and see what she can take - you're playing the role of test pilot. That's what I did and it worked.

As for radiator openings, in previous versions of the game you had to crank open the radiators all the way if you wanted to run hard for long periods, at the expense of creating more drag. Now in v4.11 that's not necessary any more. For example, in the LaGG-3 Series 4 I can firewall the throttle, set RPMs at 2300 (that will vary on it's own by a couple hundred RPM as I climb and dive. Usually when I'm making a sustained climb I'll manually adjust the RPM to 2500, then set it back to 2300 again when I level off), and adjust the mixture and supercharger as necessary per altitude. I only have to open the radiator two or three steps, and I can reliably run like that until the tanks are dry (or until I'm wounded and running home like a crying baby, or shot down, which are likely outcomes if flying the early LaGGs against an aggressive and competent foe!).

Hello!

We waited it so long and 4.11 released!

My favorite aircraft is Spitfire. I'm also trying to fly in ultra-hard realism with turned off HUD information like "Player killed", "Out of ammo", "Engine overheat!" (NoHudLog=1). In 4.10.1 and previous versions overheat on Spitfire engine started at 97-98 OIL TEMP gauge. And I even didn't understand for what there is RAD TEMP gauge - overheat started exactly at 97-98 OIL.

In 4.11 everything became harder. I can't understand when overheat starts. Sometimes it begins at one temp., and sometimes at another one. As I understand, warning sign "Overheat!" means that starts countdown to engine wreck that set random. How can I detect overheat without HUD? What algorythm of overheat on Spitfire?

Given that some engines produced by the USSR and other countries were license-built versions of better known engines, the FAA info might still be helpful. For example, the Klimov M-103 was a license-built version of the Hispano-Suiza 12Ybrs.
