I have just started with FSX after a few years on FS9, on the B737 in FSX what is the "N1" button for ?????
"N1" = Elevator trim up.
Download and print this out.
Sorry i think you may of misunderstood.
The N1 button is situated on the Autopilot panel, and seems to make some adjustment to the Engines...
Sorry if i was too vague
