Embraer’s Phenom 300 midsize jet is proceeding toward FAA and Brazilian approval on schedule by year-end. To date, all aerodynamics tests are complete on the larger Phenom derivative, including natural ice-shape flight trials. At the Sun ’n’ Fun Fly-In held in April in Lakeland, Fla., the company said the light jet was undergoing natural ice testing, as well as lightning and high-intensity radiated field (Hirf)  testing. Cold-soak tests at Eglin Air Force Base in Florida were scheduled to begin shortly thereafter, according to Embraer.
