The P2012 Traveller is an all-metal structure, high wing, twin-engine, unpressurized, piston aircraft with fixed tricyle landing gear.
The aircraft can accommodate up to 11 occupants. Suitable allowance for luggage and optional equipment is also provided both in a wide nose compartment and in the rear side of the fuselage. Easy and fast seat removal and a large rear door allows for a quick and roomy cargo re-configuration with available volumes shown in the following picture.
The fuselage is made of light aluminium alloy formed frames, beams, stringers and skins coupled by rivets and bolts.
Some major items such as beams, wing and tail surface attachments, main spar caps are made from billets.
The cantilever wing is also made by a traditional light alloy construction, with two spars configuration coupled with formed sheet metal ribs and GFRP leading edge.
A NACA five digit airfoil has been selected for the semi-tapered wing platform: this offers low drag, high maximum lift coefficient and small aerodynamic moment. Integral fuel tanks are located in the wing box, behind leading edge and between the two spars (less fire risk) for a capacity of 400 litres (106 USG) each (total of 800 litres, 212 USG).
Wide slot light aluminium alloy flaps, electrically controlled, allow low stall speeds offering potential for very steep approaches and short landings.
The vertical tail consists of a conventional vertical stabilizer and a rudder; the horizontal surface consists of a stabilizer and an elevator.
Wide trim-tabs are provided on all control surfaces, rudder is provided by standard yaw-damper as well (integrated with the standard provided automatic flight control system).
The main landing gear is composed by two fixed and robust legs containing the oleo-pneumatic shock absorber. These legs are fitted on the fuselage via a strong, cantilever beam faired by a small streamlined pods which may be easily to be removed for maintenance purposes.
The nose gear, steerable type, is fixed and consists of an oleo-pneumatic shock absorber leg, attached on the first fuselage bulkhead. It is provided by an anti shimmy damper. Two Cleveland wheels of 6.50-10 for main landing gear and 6.00-6 for nose are installed.
The primary flight controls are conventional and characterized by easy maintenance with control cables coupled by push pull rods, all visible through the immediate removal of the cabin floor nomex sandwitch CFRP panels.
1 GAMA data: Actually in US more than 1.100 piston airplanes operate as Passengers Carrying Platforms. They have now an average age of 45 years and within 20 years they will be 65 years old.
