Electra Shows High Degree of Flyability
Burbank—Lockheed’s turboprop Electra, designed for economical operation on yo-yo (up-down-up-down) flight profiles, demonstrates a saving in pilot effort that blends well with the aircraft’s work-horse mission. For example, smoothness of the transport’s Allison 501-D13 constant speed turbine engines and Aeroproducts 606 propellers help reduce pilot fatigue by cutting down sound pressure levels and heavy surges associated with large power changes and landings and takeoffs of piston-powered aircraft.
