No fuel tank management is required in normal operation.The Cheyenne III’s engines are located 30 inches farther outboard than the smaller Cheyenne’s engines, creating a much quieter cockpit and cabin. An oil-cooler “cowl flap” is under each nacelle. The eight-foot diameter three-blade Hartzell propellers are fitted with “Q-tip” 90-degree bends at the ends of their blades, adding virtual diameter without extra noise.The entrance door at the left rear of the cabin has three foldout steps, lowered into place via a pneumatic snubber, securely pinned against the 6.3 psi maximum pressure differential. An emergency exit surrounds the second cabin window on the right side. A swing- up supplemental cargo door aft of the airstair permits access to the aft baggage area without dragging luggage up the steps.The massive empennage is pneu- matically de-iced, as are the wings, and the heated windshields are fitted with wipers, operable up to 153 knots. In addition to the dorsal fin, a small ventral fin is under the aft fuselage. The dual elevator trim tabs have redundant actuators. A trim tab is also fitted to the rudder and right aileron.In the cabin, the forward club seating was supplemented by an aft forward-facing seat on the right side, along with the curtained lavatory seat in the rear. As is common, the left aft seat, next to the door, had been removed for easier boarding. Foldaway worktables and storage cabinetry facilitate inflight business dealing. Stepping over the massive main wing spar to reach the cockpit, some twisting is required to negotiate the floor-mounted yokes; the smaller Cheyennes used the Navajo’s through-the-panel control wheels. There are no storm windows on the Cheyenne III’s cockpit side windows.AUGUST 2016TWIN & TURBINE • 9
