I am looking for information on something that I believe is called a glide-slope indicator. What I know about it is:

 

It is labeled:

 

         Weston Instruments Division 

         MODEL NO. 898 TYPE NO.15

         MFR’S NO. 521273

 

The front has:

• A picture of a cross section of an airplane as viewed from the rear.

• The horizontal needle is labeled "U" and "D" which, I presume, means UP and DOWN, probably relative to the nose.

• The vertical needle is labeled "L" and "R" which, I presume again, means LEFT and RIGHT. Because airplanes tend to roll through turns I expect that this indicates roll direction rather than turn direction.

• There is also an indicator light labeled RELEASE.

 

The back has:

• A screw labeled “+” and one labeled “-“ which I expect are for application of 28 VDC standard aircraft power.

• There is also a 18 pin electrical connector.

• Eight of the pins seem to be connected together in pairs.

• Two pins (including one of the eight) are connected to each of the two previously mentioned screws.

• Three more pins  (including two of the eight) are connected to the indicator light

• Four pins don't seem to be connected to anything

 

Thanks for any help understanding this.

Is this similar to what you are describing?

Very similar!

Differences:

  • There are some minor differences in the legends on the front.
  • The picture of the plane is the same, but the Left-Right indicator on mine pivots at thee bottom rather than the top.
  • Where your indicator has a large cap at the front lower left, mine has an orange lamp labeled "RELEASE."
  • Mine only has one connector on the back (18 pins).

If I can figure out how to do it, I'll post photos.
