Aviation Related Presentations
and Information

I have created several presentations on soaring and aviation related topics such as avionics wiring, emergency devices, oxygen systems, transceiver troubleshooting, trailer wiring, and much more.

See this web page for more details.

Avionics Related Manuals and Information

I have accumulated a repository of manuals and information from various avionics manufacturers. Some are very old and hard to find. To help others I have been uploaded some of those manuals to my web page. Of course, the manufacturer's web site may very well have a later version of the manual than I have stored here.

Go to this repository to download the files.

If you don't see something that you are looking for please drop me an email. I probably have it. You can find my contact information on the
Soaring Society of America member's Web Site
