The sliding panel in the roof is provided with a wind-screen, so that when travelling " outside " the passenger is protected against the wind. Particular attention has been paid to the accessibility of the engine. The two aluminium, side panels are hinged along the bottom longeron, and fold down after undoing a few bonnet fasteners, thus giving easy access to the Wolseley Hispano engine. The span of the machine is 46 ft. 6 ins. and the length 30 ft. 6 ins. The total wing area is 550 sq. ft. The maximum speed is about 100 m.p.h. and the cruising speed 85 m.p.h. The landing speed is approximately 38 m.p.h., and the machine climbs to 5,000 ft. in 7^ mins. Fuel is carried for a range of about 450 miles. i ' ..i, r The Westland 6-Seater Limousine ' 450 h.p. Napier •• Lion " Generally speaking, the machine entered "by the Westland Aircraft Works of Yeovil is similar to that firm's well-known standard four-seater Limousine. It is, however, a con- siderably larger machine, and seats five passengers instead of the three of the standard machine. Also the power plant is a 450 h.p. Napier " Lion" in place of the Rolls-Royce and Hispano engines fitted in the smaller model. In general arrangement, however, the Competition machine follows the well-known Westland. That is to say, the cabin is between the planes, and the pilot is seated to the left of and slightly above the aft passenger. This arrangement impresses one as quite a good solution, giving the pilot a good enough view without placing him so far back as to upset his " feel " of the machine. The engine is the 450 h.p. Napier " Lion," which has already a reputation for reliability and smooth running. The engine mounting is of tubular construction, cross-braced with steel cables and extremely rigid, and the whole engine unit is separated from the machine by a fireproof bulkhead .of asbestos covered with aluminium sheet. This is a point well worthy of notice, and throughout the design and con- struction every care has been taken to avoid any possibility of fire. As a further protection the petrol tanks are carried under the wings.
