EFC Position?

[xavnl]

Hey!

 

Before start checklist said EFC on Pos1.

When entering the plane EFC is on Pos2.

 

What is the difference?

I can't find it in the manual, in the NATOPS maybe?

The EFC switch selects which DECU (1 or 2) is active. They are redundant systems. Part of post start (forget which checklist) is to to check that both are functional, and that the EFC warning light works. It should flicker when you switch between 1 and 2.

Perfect.

Thanks.
