Sandel Avionics received FAA technical standard order (TSO) certification of its new vibration-resistant SG102 attitude- and heading-reference system (AHRS) for helicopter applications. The SG102 is certified for primary heading reference and offers helicopter operators a solid-state replacement for electromechanical directional gyros. When packaged with Sandel’s SN3500 or SN4500 displays, it offers a complete compass system upgrade.
