L-3 Communications’ Avionics Systems division has certified the company’s Trilogy ESI-1000 electric standby instrument for installation in helicopters. It can serve as a backup should the aircraft’s primary flight instruments fail.
The Trilogy has its own integrated air data computer, solid-state attitude sensor and can be ordered with an optional external magnetometer for heading information. The Trilogy depicts attitude, altitude, airspeed, and heading information (if accompanied by the magnetometer).
The helicopter version of the Trilogy is calibrated from 20 to 350 knots and -1,500 to 55,000 feet. It can detect roll rates up to 100 degrees per second. The instrument measures four inches wide by three inches high, weighs 2.75 pounds, and its list price is $15,000.
AOPA Pilot Editor at Large Tom Horne has worked at AOPA since the early 1980s. He began flying in 1975 and has an airline transport pilot and flight instructor certificates. He’s flown everything from ultralights to Gulfstreams and ferried numerous piston airplanes across the Atlantic.
As the cold weather chills AOPA’s Headquarters in Frederick, many of us are inside generating new resources for flying clubs.
In my house, every Friday night is “Movie Night.” While the movies are rarely educational (I don’t think I learned anything from the Lego Movie), we look forward to the weekly opportunity to spend time together. Why not use the same concept for your Flying Club (with the addition of education, of course)?
AOPA Flying Club Manager Kelby Ferwerda posted the following on the AOPA Flying Club Facebook Page: “Recently I’ve talked with quite a few Flying Clubs about maintaining social activity through the cold winter months. Some clubs host Holliday Parties, others have Potluck Movie Nights. What does your club do to keep members involved during the chilly months?”
