The petrol is forced by air pressure from the
two lower tanks into the gravity tank and is obtained by a hand
pump fitted outside the car alongside the pilot's seat. The oil
tank is fitted inside the car in front of the observer.
The observer's seat is fitted abaft the engine and the pilot's
seat is aft of the observer. The observer, who is also the
wireless operator, has the wireless apparatus fitted about his
seat. This consists of a receiver and transmitter fitted inside
the car, which derives power from accumulator batteries. The
aerial reel is fitted outside the car. During patrols signals
can be sent and received up to and between 50 and 60 miles.
The pilot is responsible for the steering and the running of the
engine, and the controls utilized are the fittings supplied with
the aeroplane. Steering is operated by the feet and elevating by
a vertical wheel mounted in a fore and aft direction across the
seat. The control wires are led aft inside the fairing of the
fuselage to the extreme end, whence they pass to the elevators
and rudders.
The instrument board is mounted in front of the pilot. The
instruments comprise a watch, an air-speed indicator graduated in
knots, an aneroid reading to 10,000 feet, an Elliott revolution
counter, a Clift inclinometer reading up to 20 degrees depression
or elevation, a map case with celluloid front.
