For over 35 years we have specialized in performing the Altimeter, Static System, & Altitude Reporting tests required by FAR 91.411, and the Transponder tests required by FAR 91.413.

We do these tests at your location in most of Northern California.

In 2001, we added digital altimeter/airspeed test instruments and the capability to test Mode S. This new equipment significantly increases the accuracy and reliability of our tests.
