Aspen Avionics is marking the fifth anniversary of the initial certification and shipment of its Evolution E5 dual electronic flight instrument. First announced at the 2018 Aircraft Electronics Association convention, the E5 received AML-STC approval for over 300 aircraft models later that year. Aspen introduced new features including a horizontal situation indicator (HSI) and optional advanced software package for true airspeed, outside air temperature, wind direction and speed and WAAS GPS mode annunciations in 2020.
