Real Glass Instruments

[fredd3039]

Hello,

I recently acquired an entire engineers station from a 727. Every panel, every knob, every switch, every instrument.

 

Three of the instruments are glass. The plates on the back say they were made by Si Aerospace in Feb of 99. The plane they came out of was parked at the salvage yard a year ago and is being dismantled. The instruments normally would have been tested and tagged and showing a trace of no incident. I am assuming they are functional. My question is can they be used on a sim and if so how do I test them to check to see if they are ok other than plugging the umbilical into another 727.

There are 18 pins on the bottom in a 2,4,5,4,3 stacked configuration.

Any help would be greatly apreciated and no I don't have Building simulated aircraft instrumentation. Mike I hope you read this one.

I strongly suggest you go to wherever you got the parts from, and acquire a 727 wiring diagram...

 

Using the wiring diagram, you can see which pins to put what voltage to in order to at least make the needles move.

There is a chapter in Building Recreational Flight Simulators called Using Real Instruments. It provides a pretty good overview of which types of flight rated instruments can be used in simulator applications.

 

Many engine gauges accept synchro signals. These are signals which can be generated by a digital-to-synchro interface. There's a DTS project in BRFS.

 

The book Building Simulated Aircraft Instrumentation doesn't cover this topic.

There is no needle. These are micro video screens.
