'+' Symbol on avionic equpiment
 

Hi,

The other day while in the cockpit of a 737, I noticed that most of the equipment in the cockpit had a small "+" symbol on it. Does anyone know the significance of the symbol?

Thanks.

It is where the electrical connection for the panel lights is. Push the + to make a good connection. Often have to do this in flight on our old Airbuses.

It shows the location of the small coax type connector for the panel lights

Hey conspicuity......Pity you did not notice that DIXI188 has more than answered the original question.......

Hello MQZ4:

Welcome to Pprune, I notice that your question is also your first post here in the forum.

The "what the heck does the + symbol mean" question comes up about once every 18 months or so, kind of like a lunar eclipse :) . There is a longer post about this, including some good pictures of the front and back sides of an electrical panel with a + symbol on it, at this link: Small crosses drawn all over cockpit panels.

If you don't want to go read that whole discussion, I have reproduced the photos below, they are pretty much self-explanatory.

Again, welcome to the Pprune Forums.

Michael
