A320 ovhd pnl blue + marking
 

Hi there, does anyone know the reason for the small + blue marking on the each section of overhead panel in A320 or Airbus family?

thanks in advance

yes .it is where the electrical connections are for backlighting the panel....
i.e if panel not lighting push the blue +.


boeings also have it on all there panels in flight deck..

hope that helps
cheers

I've never seen that blue +. Can you point it to me?

I don't work on 320's but here's a picture I have of a 330, I've added a couple of arrows.
