L-3 Aviation’s ‘Trilogy’ ESI an Enstrom Option

L-3 Aviation Products (Booth No. N4505) announced at the NBAA Convention that Enstrom Helicopter has selected its Trilogy ESI-2000 electronic standby instrument as an option for the Enstrom 480B helicopter.

The Trilogy ESI-2000 provides attitude, altitude, airspeed and optional heading data on a 3.7-inch digital screen. It mirrors the layout of the Enstrom 480B’s primary display, facilitating a quick transition to back-up flight information in an emergency, while reducing weight and saving panel space, L-3 says.
