Little Rock, AR | April 21, 2014 - Avionics & Systems Integration Group (ASIG) has announced today that the company has been awarded a Supplemental Type Certificate (STC) by the Federal Aviation Administration (FAA) for the installation of an L3 AN/ARN-154 TACAN system and Sandel SN3500 EHSI system on the Enstrom 480B rotorcraft.  The certification has been accomplished in cooperation with Enstrom Helicopter Corporation and Helicopter Specialties, Inc. of Janesville, WI and has been undertaken in support of a foreign military service customer.
The L-3 airborne TACAN AN/ARN-154(V) is the world's lightest and smallest TACAN ever produced at only 6.5 pounds and is the only multi-station tracking TACAN available in the world. The system has the capability to track up to four ground stations simultaneously in range and two in bearing. Tracking velocity is up to 1800 knots.  The complete TACAN system consists of an RT-1634(V) Receiver/Transmitter; TACAN Control Unit with mounting base; and an Indicator Unit ID-2502. The system can be used for Air-to-Air and Air-to-Ground operations and meets MIL-STD 291C and NATO STANAG-5034. 
The Sandel SN3500 EHSI is a sunlight readable Primary Navigation Display which features an ultra-wide-angle field of view and LED-backlit illumination.  When installed with the L3 AN/ARN-154(V) TACAN on the Enstrom 480B, the platform provides improved situational awareness by presenting compass map, flight plan and RMI data in a bright, crisp and easy-to-read format which can be configured for NVIS flight operations.
