L-3 Avionics Systems has received FAA certification for its all-in-one standby attitude instrument with a backup power source.
The Trilogy ESI-2000 shows aircraft attitude, altitude, and airspeed (and optional heading) on a 3.7-inch glass display, and it can operate up to four hours on its own power after an aircraft electrical failure. The Trilogy was developed using the FAA’s highest safety standards, company officials said.
“Many of today’s aircraft are operated solely by reference to electronically displayed flight information, which significantly increases reliance on the electrical system,” said Larry Riddle, vice president of business development at L-3. “The Trilogy ESI-2000 gives pilots the clarity and precision they are accustomed to seeing on a primary flight display, while also acting as a safeguard against possible electrical failure. With the ability to operate independently after a power loss, the ESI provides the information the pilot needs to make a safe landing.”
The Trilogy ESI-2000 is an advanced solid-state standby instrument designed to replace electro-mechanical standby instruments. The Trilogy display is designed to look like a smaller version of a primary flight display so that the transition to reading it in an emergency is simpler for pilots.
