A320 Basic Lighting Question

[Atomic_Sheep]

Hi guys, there's obviously a lot of different light knobs and switches in the airbus that turn different lights on and off but I just wanted to rectify a few things in regards to backglighting.

In the four images, we have the overhead panel backlighting. That is controlled by the "OVHD INTEG LT" potentiometer knob located on the overhead panel.

There is also a potentiometer knob on the centre pedestal titled "INTEG LT MAIN PNL & PED". So quite obviously that does the same job as the overhead one only for all the backlighting for the centre pedestal and the main panel.

What about the backlighting for the glareshield? Is there a knob somewhere for that?

Are there any other backlighting knobs anywhere that I'm unaware of?

Lastly, I just wanted to make sure I'm not missing something... essentially there appear to be just two light knobs in the whole cockpit of the A320 that deal with backlighting? I'm just talking about panels with knobs and switches... not talking about any other lights that are also present that illuminate the cockpit itself.

I'm starting to design the electrical part of the cockpit and build everything else around that and since I'm planning on having every panel totally hot swappable and thereby easily removable/replaceable/reparable, I need to know which knobs connect to what and which panels connect to what and I hope you get the picture.

Hello,

for the glareshield, there are pots located on the bottom of the glare section, one for the FO one for the CPT, this is detailed in the LIGHTS section of the FCOM (there is one available in the donwloads here).

I've d/l some files from the downloads section but I don't recall seeing what you are referring to. What does FCOM mean?

Also... are these the pots that you are referring to (see attached pic)? I think there appears to be 4 of them, or is that done so that the pilot is able to adjust the brightness with the left or the right hand depending on the situation?

Hello,

I believe there are two of them, one adjusts the backlighting intensity and the other the displays brightness.

Try that one, http://www.mycockpit.org/forums/downloads.php?do=file&id=25
FCOM stands for Flight Crew Operating Manual.

See the chapter 1.33, and particularly the page 706 (of the PDF file).

On your picture we can see the two pots belo the FCU unit. One is for the integral lighting of the glareshield and the brightness of the LEDs, the second one is for brightness of the FCU displays (7segments digits).

There are 2 other ones, not visible on your pic, but located on both ends of the glare, which adjusts the lighting of the sliding table and map holders (one knob for the CPT and one for the FO).

Hope its clear enough this time ;)

Excellent! Thanks for your replies.

If you wish to send me a email I will provide you with my phone # on the Sunshine Coast and I will provide you with all of the lighting info for the flightdeck that you may require if your intention is to build a complete replica of the lighting system of an A320.

Cheers

Thank you for your offer. I will keep it in mind for when I get into to the serious development of the overhead.
