A very quick question about the Cessna 172

When turning on avionics in the glass cockpit 172, do you use both avionics 1 and 2, or only 1 of the avionics? im doubting so I thought I should ask

Personally for realism purposes I don’t turn the Avionics on until the engine is running.

my engine is running, i know why you should turn them on after start, but i dont know if to use both avionics or 1 of them

Oh use both of them because one is ur right screen and left is the other. If you cut them on prior to the engine on it will drain the battery and voltage and be hard for the plane to start.
