State of build in September 2000

The pilot's cockpit is now complete (left) with the magnetic compass, the repeater compass and DF meter fitted, the last two items being mounted above the pilot's panel on a separate bracket. The RH picture is a close-up of the H2S gear now fitted at the end of the navigator's bench, carried in a framework that swivels on a steel pole that runs from the floor to a support on the canopy


The picture on the right shows the Navigator's bench with the Nav's panel at the back, an anglepoise lamp and other navigation instruments fitted on the panel. The unit on the extreme left of the picture is the 'API' or Air Position Indicator. A Mileage unit, fitted below the Nav's bench, converts the forward air pressure from the Pitot tube (an open ended tube facing forward in the air flow) into a rotary speed such that the rotational speed is proportional to the air speed of the aircraft. A flexible cable couples this rotary output to the API and together with an electrical signal (compass bearing) from the Master Gyro Compass, produces an output on two counters on the front of the API, that read directly in degrees and minutes of latitude and longitude. (GPS system in WWII ?)

The picture on the left is another view of the starboard side of the Lancaster and shows the Flight Engineer's panel, the Drift Sight and the Oxygen Economiser. The Drift Sight is a telescope fitted with a graticule that can be rotated and looks vertically downwards to the ground. The graticule can be turned such that objects on the ground track accurately along the lines of the graticule. By noting the angle of the graticule, as shown on a scale fitted to the sight, plus other parameters, it is possible to work out the drift, due to effect of side wind on the aircraft
