S-Tec (Booth No. 2293) has approved Sandel Avionics (Booth No. 4642) SA4550 primary attitude display for use with S-Tec’s System 55, 55X, 60-2 and 65
autopilots following successful flight testing.

The SA4550 display uses Sandel’s patented rear-projection display technology with LED backlighting. It has a 180-degree viewing angle, bright color rendition and a mean time between failure of more than 10,000 hours. S-Tec has received STC approval for the installation of System 55, 55X, 60-2 and 65 autopilots in numerous aircraft, including turboprop models such as King Airs and Twin Commanders. The installation of the display will in most cases be covered under Sandel’s STC-approved model list but can also be approved through FAA field offices.
