4.11 - Engine: Overheat!

[Koss]

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?
