Current Products


A leading innovator in avionics display systems, Sandel currently offers four advanced products, including the new SN4500 4-ATI Primary Navigation Display; the new SA4550 4-ATI Primary Attitude Display; the SN3500 3-ATI Primary Navigation Display; and the ST3400 3-ATI TAWS/RMI. All four systems use Sandel's exclusive patented "light engine" display technology, a third-generation, rear-projection system similar to the displays found on the world's new military aircraft. Featuring a high-reliability backlight, our advanced displays provide true 180-degree viewability in both the horizontal and vertical axes, along with higher contrast and sunlight readability than traditional electronic CRT and AMLCD screens.
