Enstrom Helicopter Corp., Menominee, Mich., said it chose Chelton Flight Systems’ Electronic Flight Instrument System (EFIS) for its Model 480B helicopter program. Enstrom said it will certify the Chelton EFIS as a part of the factory type certificate for the 480B turbine line of helicopters. This factory-installed configuration is expected to be available this year. The installation will include two Chelton EFIS displays, Chelton’s compact digital air data and attitude/heading reference system and its Beta 3 GPS/WAAS (Wide Area Augmentation System) receiver. The system also features a synthetic vision primary flight display, dual integrated flight management system, Class-B (or –A capable) helicopter Terrain Awareness and Warning System, a master caution voice warning system, Highway-In-The-Sky navigation, a digital flight recorder and Chelton’s hover vector display. The 480B includes a fully configurable cabin that has been used as two place surveillance aircraft, a three-place advanced trainer and as a three- to five-place VIP aircraft.
