So what happens if you turn 2 and 3 off and it turns out number 1 is stuffed.
Why don’t you look up first and check if one has an amber light illuminated before you rush in and turn two good ones off.
3 ADRs off results in a world of hurt/BUSS.
And when you’re looking up switching 2&3 off the F/O loses his instruments.
