STEC AP 55 question

I have a Stec 55 (non X) installed

on my first recent night flight I noticed that the face is not illuminated – is this normal or just on may one not working?

thanks for the help


The basic 55 computer has an extremely dim display. This issue and adding roll steering are the significant differences when upgrading to a 55X

Backlight failure on those is really common.

Here’s a poll that was taken on the COPA forum a while ago:-
