Sandel Avionics (Booth 4642) and S-TEC have announced the successful testing of Sandel’s SA4550 Primary Attitude Display with S-TEC’s System 55, 55X, 60-2 and 65 autopilots. S-TEC will now list the SA4550 as an approved flight director for use with these autopilots.

The SA4550 Primary Attitude Display is a 4-ATI sized display that uses Sandel’s patented rear-projection display technology with LED-backlighting for maximum sunlight readability, 180° viewing angle, bright color rendition and an MTBF of more than 10,000 hours.

Both single- and dual-cue flight director command bars are supported and can be toggled by the pilot. The SA4550 can also be combined with the SN4500 Primary Navigation Display which functions as an Electronic-HSI with a full-color moving map that has the capability to show flight plans, bearing pointers, Stormscop and optional traffic and weather overlays. The SN4500 is also compatible with S-TEC autopilots.

S-TEC’s System 55, 55X, 60-2 and 65 are full-function autopilots that have received STCs for installation in numerous aircraft, including turboprop models such as Beechcraft King Air and Twin Commander.


Jerry Henry, Sandel’s director of sales, says: “This opens the door for numerous aircraft owners, especially in the turboprop market, who would like an affordable upgrade for their flight directors and autopilots.”

Greg Plantz, S-TEC’s director of sales and marketing, says: “The Sandel high-definition attitude and navigation displays are fantastic replacements for worn-out mechanical flight instruments. Because they are modular replacements, they deliver an amazing array of digital display capabilities without needing to totally replace an entire panel.”
