JANUARY 8, 1920 -a m • m H H The Farman " David," a small two - seater bi- plane with 60 h.p. Le Rhone engine " Flight " Copyright a H H SBBHBBiB it which is rather pleasing. Fitted with two Salmson engines of only 260 h.p. each, the machine carries 20 passengers and has a speed of 100 m.p.h., which is extremely good. From the table published in our last week's issue it will be seen that while the weight of the machine empty is 4,400 lbs., the weight fully loaded is 10,200 lbs. This ratio is somewhat unusual (43 • 1 p er cent.), and points to very light construction. Probably no other machine at the show can boast a similar ratio. Out of the load carried fuel occupies about 1,400 lbs., the useful load, apart from fuel, being 4,400 lbs., or equal to the empty weight of the machine. One takes it for granted, of course, that the requisite factor of safety is provided, in which case the structural weight of the " Goliath " is very low, as the figures show. The two Salmson engines are placed on the bottom plane, comparatively close to the fuselage, and compared with some twin-engined machines the centre of thrust appears to be yery low. The tanks are carried in the engine nacelles, behind the engines. The pilot sits with his head projecting into the open, in the left-hand side of the fuselage ahead of the wings. The passengers are well provided with windows and the view, especially from the forward ones, is extremely good. Admission to the cabin is by means of an ordinary door in the starboard side.

This little machine, the " David," has made several notable flights, piloted by the Farmanpilot, Bossoutrot, among which may be mentioned one from Paris to Biarritz.
