Homepage for Catrax Inc. and Lytle Johnson
Last updated 13 April 2010

Update note: Added a video and notes about the North Star aircraft. It's DONE!

Catrax Inc. is a Washington corporation providing technical services. Current activities include software development (embedded realtime applications, digital signal processing, general software support) and aviation services (pilot services, A&P mechanic services, and small-scale development of specialized aircraft gadgets). I am Lytle Johnson, president and principal technician. I've been developing software for many years, primarily for embedded real-time applications with an occasional application for larger machines. My formal education is in engineering and applied mathematics. I've been doing aviation for even more years, starting with a 3rd place in Junior FAI Gas free-flight at the 1958 Nationals at Glenview Naval Air Station, Glenview, IL.

Aviation credentials: Basically I like being in the air and looking around, so mostly I fly low slow airplanes.
