Can this be done?

It actually happens lots in most aircraft, especially when the start switch is thrown.

It would be a Neat effect, I would connect your monitor power supplies through relays attached to your start buttons. That would work excellent.

Level D 767 does it if I am not wrong... and it happens in most planes when there is a change of Generator there is a slight power interruption during the change and depending on the Bus they are attached to that is the screen that blinks!

Sorry, but this looks like last century solution...
I don't know what PM you have, but PM regional Jet nicely goes from dim to off and from off to brighten simply via Master Avionic Switch. All you have to do is write 0 or 1 to 0x2E80 offset.
Works great, looks nice and I think works better than playing with power supplies, relais and all that "hardcore" stuff.

But the problem with doing it the way you suggest, is if you have turns off everything that is being controlled by the Avionic switch.

thats all.

Hi,

If I understand well, when battery is closed you want the PFD/GC screens to be blank and when the battery is on the sceens to go on with auto dimming.

In this way it is possible throu the PFD/GC menu. Press Esc to enter the menu then enter OpenGl oprion and check the and check opengl dimming

This are events you can program in PMSystem I think.

No he wants to achieve the out and dimming when he changes from Bat to Gen bus, etc.

Somethink like that or similar should work

[logics]
55F0 0 CPFD
55F0 1 CND
55F0 2 UECAM
55F0 3 LECAM
55F0 4 FND
55F0 5 FPFD

if (genbus1 = 0) or (genbus2 = 0)
then
CPFD = 0
CND = 0
UECAM = 0
LECAM = 0
FND = 0
FPFD = 0
else
CPFD = 100
CND = 100
UECAM = 100
LECAM = 100
FND = 100
FPFD = 100
endif

Of course... Pmsystems comes through again...

Great stuff, Thanks.

Well, I would like to know how to make the displays turn OFF once the Avionics Master Switch is turned OFF. When I turn ON the BATT and then the MASTER AVION switch, the displays spring to life. Turning them off only turns OFF the GF166 and the reception of ATC/ILS/Navaid data on the displays.

Thanks,

Mine turn off fine, what offsets are you using?

in the 737 logics file, should i add all these lines in it, and does it mather where i place all the lines ?

I was just about to ask the same question. 777/767
