L-3 Avionics’s Trilogy electronic standby instrument received TSO approval from the FAA for use on Part 27 and Part 29 rotary-wing aircraft, according to the Grand Rapids, Mich.-based company.
The FAA is expected to issue the first Airworthiness Directive on the Eclipse 500 VLJ in the next few days, restricting the jet to day VFR flight because of a pitot/angle-of-attack probe freezing problem that occurred on three flight-test airplanes. Until the AD becomes effective, the Eclipse 500 can be flown IFR but not in IMC, pending installation of a pitot tube fix. The problem took place after takeoff in high-humidity conditions.
