Dec 27, 2021     Instrument layout - (0.5 hour)       Category: Avionics

With my son home from University for the holidays, I had him draw up my proposed layout for the radio and intercom for the rear panel.

The original radio was panel mounted fitting into a standard 3-1/8" instrument hole. A friend referred to the radio as an old "coffee grinder" style. It appears to have had radio and intercom functionality. See attached picture.

I want to install a new radio in the same hole without cutting into the original panel. My plan is to use a Trig TY91 remote head radio with a Sigtronics Sport 200 intercom mounted underneath it. My plan is to mount them stacked on an insert mounted within the original 3-1/8" hole.

See attached drawing of the layout.

Received a package from Ray, just in time for Christmas. It included the second airspeed indicator and the missing manifold pressure gauge. Additionally, it included a French-English Aerospace Dictionary from 1973. This is a real treat because it properly translates the words that Google Translate doesn't quite work out.

For example, the term "Casque" on the instrument panel took me a while to figure out. Google translated it to "Helmet" but the more accurate term would be "Headset" which makes a lot more sense. Initially it wasn't quite so obvious since the original headset jack was only one plug, not the typical two plug system that is used today.
