smooth interior experience, thanks to 236 vibration absorbers, plus insulation, that totally separate the cabin shell from the airframe. We were told the 350i’s cruise noise level is on a par with that of typical jets, and an inflight tour of the cabin proved the worth of that claim. Maximum pressurization differential is 6.6 psi.
Up front, the familiar King Air NACA inlet on the side of the nose is missing; an improved air conditioning system has obviated that blemish. The three landing/taxi lights on the nosegear are supplemented by any-speed recognition lights in wingtip fairings, which also contain strobe and navigation lights. The 350i’s winglets are a Beechcraft design, increasing the effective wingspan beyond the aircraft’s already- impressive 58 feet.
The nacelles for the PT6A-60A 1050-shp engines have hinged, prop-open sides for easy inspection and maintenance access; hot exhaust gases circulate continuously through the lips of the induction air inlets, so engine anti-ice is always on with no bleed- air penalty. The inlet bypass vanes are actuated electrically, with standby motors provided if the primary actuator fails. Clever airflow control devices between the exhaust stacks and the nacelle sides keep sooting to a minimum. The four-blade Hartzell propellers are 105 inches in diameter, turning a slow 1,900 rpm at takeoff, but normal cruise is conducted at 1,500 rpm.
Standard Raisbeck wing lockers aft of the engine nacelles add space and 300 pounds of carrying capacity on each side,
