3.5 Static Port Connection
The STX 165 has a built-in altitude encoder that requires connection to the aircraft static port. The
static port connection is on the back of the STX 165. To ensure a leak proof fi t, it is recommended
to use tubing with an Inside Diameter of .125” and secure it with a hose clap or ty-wrap. Upon
completion of the STX 165 installation a leak test of the static line is to be performed per
FAR Part 43 Appendix E.
