Airspeed AS.10 Oxford, part nine, British users part two

The Airspeed AS.10 Oxford was a low-wing twin-engine cantilever monoplane with a semi-monocoque fuselage, a conventional landing gear configuration and a wooden tail. It was thanks to its configuration that it could replicate the flying characteristics of any frontline aircraft of the moment. It was specifically designed for a wide range of training missions such as navigation, flying instruction, night flying, instrument flying, wireless radio training, direction finding, gunnery and vertical photography. The Oxford was specifically designed to include various modern innovations and equipment fittings like a full array of instruments and controls within the cockpit which were very useful in the trainer role. Additionally it could also be used in additional roles such as air ambulance or maritime reconnaissance.
Regarding the flying experience, the Oxford was representative enough to give the pilots the experience needed to migrate onto larger aircraft with ease while possessing smooth flying characteristics.
It was operated by a crew of three, with the seating arrangement being interchangeable to better suit various purposes, such as to better enable a specific training role. The cockpit featured dual controls and a pair of seats in order to accommodate a pilot and either a navigator or a second pilot alongside. When used for bomb aimer training, the second set of controls was removed and the freed space was used for a bomb-aimer in prone position. When used as a navigator trainer, the second seat was pushed back so it would be in-line up with the chart table. Aft of the cockpit was a wireless operator station facing aft of the starboard side of the fuselage. The turret present in the Mk.I version of the Oxford, could also be used for gunnery, navigation, wireless, bomb-aimers or camera operators. The centre section could host up to 16 11 lb (4.98 kg) which could be released via bomb-release switches installed at the pilot and bomb-aimers' stations.
The Oxford was normally powered by a pair of Armstrong-Siddeley Cheetah X air-cooled radial engines which yielded 340 hp each. Those were initially outfitted with wooden fixed-position De-Havilland-built propellers but it was initially designed to have variable-pitch propellers. The starboard engine drove a hydraulic pump and air compressor with this one being used to actuate the undercarriage and flaps and the pump being used on the brake system. The port engine drove a 500 -watts electrical generator. The engine cowling featured an inlet that drew cooling air into a tank. A pair of tinned steel oil tanks were also contained within the cowling. Welded steel construction was used for the nacelles.
