View Full Version : Flight Illusions Overhead Gauge Lighting

09-09-2009, 02:31 PM
I haven't been able to get the FI Overhead Gauge lighting to work. PM Systems scans and finds all of the gauges and they work fine except the background lighting. The nav lights turns on every other background light including the FI Standby gauges, Flap gauge and Boeing Clocks, but not the Fi Overhead gauges. The only way I have been able to make them work, is run the FI GSA App and run the default config and trun them on manually, exit the app and start PM Systems. Very strange.
Anybody know what turns them on. I am using the 737 logic

You don't need FI APP to run together with pmSystems and for FI backlight just turn on WING Light, it should work...;-)

By the way anyone knows how and where to change FI OVHD Backlight in pmSystems from WING light to INSTRUMENT Light using offset 0DC0 bit 5 ?

I am not using Flight Illusion Software together with PM Systems. I only use it to turn on the background lighting of the FI overhead Gauges, then exit and then start PM Systems. Its the only way I have been able to make them work. I have been unable to turn them on or off with with Nav lights/strobe switch when PM Systems is working. All of the other background lighting works with the Nav/Strobe light switch except the FI Overhead gauges. I have e-mailed Mark at Flight Illusions and Tech Support at PM. PM Support said its not there product and sent me to Flight Illusions. Mark blew me off. I have spent several hours trying to resolve this issue with no luck.

From what I can tell, Carlos answered your question, stating that the backlight in the OVHD gauges is controlled by the WING light switch on the PMSystems overhead. In your reply, you cited only the inability to make anything happen using the Nav/Strobe light switch.

Have you tried cycling the wing light switch to see if that solves your problem?
