Does anyone know what the little white arrow indicates on the engine boost(ata) gauge in the Bf109G6AS? It's at about 1.4ata. Also, what do the red and white arcs indicate?

Thanks,

DangerForward, I don't have any reference in front of me, but as a guess I'd say the triangle is the ops limit for non-MW50 operation. This should be at 1.42 ata, consistant with earlier versions of the engine. As for the red and white arcs, I have even less of a clue. My best guess is that they define the zones of non-time limited engine operation (max continuous power.)

A reference for those who want to see what we're talking about without firing up the sim is here:

I'd wondered if they marked the continous operation engine settings. I now always cruise with the engine at the level of the diamond mark. Previously I noticed that when I flew the G6AS I was always overheating when I flew around at 100% eventually, so I thought the cruising engine setting must be less than 100% throttle.
