The Farman F.300 was a
trimotor semi-
cantilever monoplane airliner. The relatively low
wing loading and balance of the aircraft were such that instances of
motion sickness were claimed to be relatively low amongst the aircraft's passengers. The aircraft featured mixed construction, being made of wood,
duralumin, and
fabric. It was typically powered by an arrangement of three
Salmson 9Ab radial engines; they provided plentiful reserve power and thus were typically operated at a reduced power set, which was relatively fuel-efficient, caused less wear, and also reduced risk of engine failure. These engines were arranged with one being in the nose aircraft while the other two were housed in lateral
nacelles that were bolted directly onto the underside of the wing in a relatively
drag-efficient manner. Due to the positioning of the engines, as well as the fitting of
silencers, relatively little vibration or noise was inflicted upon the passengers. To ease handling issues in the event of a single engine outage, the three propellers driven by these engines were placed relatively close together. The aircraft could fly indefinitely on only two engines. Various ignition systems could be used to start the engines, including Farman's own combination starters, cartridge-based systems, and other means. To address the threat posed by an engine fire,
fire extinguishers were mounted on the engines while warning indicators were provided within the cockpit. The high-mounted wings of the aircraft were directly attached to the upper portion of the fuselage. The undercarriage has been credited for the aircraft's relatively high stability during take-off runs, even from inhospitable terrain, while the brakes permitted the landing distance required to be significantly shortened as well. Careful use of the brakes prior to starting the take-off run could also shorten the distance required. Via a series of windows along the sides and top of the cockpit, the pilots were provided with favourable external visibility across most directions; the side windows could also be opened and closed to the pilot's preference. The windows were intentionally inclined to deter adherence by
rain and thus visibility becoming obscured. ==Operational history==
