Forward carry-on baggage lockers, underseat baggage stowage, rear baggage compartment. Forward door, incorporating airstairs, on port side. Upward-hinged rear cargo door, also on port side. Three emergency exits over wing (two starboard, one port). Accommodation air conditioned, heated, ventilated and pressurised. Executive and corporate shuttle options seat between 10 and 18 passengers with options for forward and rear compartments, combination lavatory/passenger seat and two beverage bars at cabin compartment division. Club, double club and triple club seating optional. Customised interiors to customer's choice.

SYSTEMS: Bleed air cabin heating and pressurisation, maximum differential 0.35 bar (5.1 lb/sq in). Air cycle and vapour cycle air conditioning. Hydraulic system, pressure 207 bars (3,000 lb/sq in), for landing gear actuation. Electrical system includes two 300 A engine-driven starter/generators and one 34 Ah Ni/Cd battery. Constant flow oxygen system of 4,420 litre (156 cu ft) capacity standard. Engine inlet screen anti-ice protection, exhaust heated engine inlet lips, fuel vent heating, electric propeller and windscreen de-icing systems standard. Brake de-icing optional. Pneumatic de-icing boots on wings, tailplane, tailets and stabilons.

AVIONICS: Comms: Collins Pro Line II digital technology radios; cabin briefer; cockpit voice recorder. Flight: Dual flight directors; GPWS; provision for TCAS1. Loran optional.
