Rusty Pilot Posted April 14, 2020 Report Posted April 14, 2020 I noticed an asterik on my EGT gauge. I am not sure what it is for, but it seems to align somewhat with a 50 degrees ROP operation at most flight levels when leaning the engine. This is in my 1974 Mooney 20C. Can someone tell me it's purpose and if it was intended as a tool for leaning the fuel mixture? I'll take a picture of it next time i am flying
Hank Posted April 14, 2020 Report Posted April 14, 2020 Yes, it's a reference point. Some EGTs have "*" and no numbers; putting the "*" makes it easier to tell which line was peak. My EGT conveniently has numbers every 100°F.
carusoam Posted April 14, 2020 Report Posted April 14, 2020 Set it up/adjust it.... calibrate(?) it so the needle points to the asterisk when at peak EGT... On a numberless instrument... calibration isn’t exactly the right word to use... For more information, there is an Alcor site that will have the details that you seek. https://alcorinc.com/PDF/59185.pdf PP thoughts from old fuzzy memories.... Best regards, -a-
