crow0827 Posted October 2, 2020 Posted October 2, 2020 Hi, All, ED, 3rd Party Developers. I have noticed a few things and would like to share them with you. Did you know that the control panel backlighting in general is regulated by the Military Standard as to what should and should not be illuminated? According to MIL-P-7788E, the connector for powering the light source for the backlight is marked with a white cross. 3.4.1.2 Connector location. A cross (+) approximately 0.08 inch by 0.08 inch shall be located on the front surface of the panel approximately above the electrical connector; except when required nomenclature interferes which the marking, the cross (+) shall be located as close as possible to the electrical connector. The cross (+) shall be of a white color over the opaque surface and shall not be illuminated. Where practical, the connector should be located at the center of the panel. I've checked on more than one plane, and the white cross are illuminated. I haven't seen the actual panel, so I can't say for sure, but I'd like you to check it out a bit. As far as I know, even non-military aircraft are designed to this standard, because the panels I've seen in real life didn't have illuminated cross.
