AVRO LANCASTER LEFT & RIGHT BEAM INDICATOR

One of the main navigation aids for British heavy bombers such as the Halifax and Avro Lancaster was the aircraft’s  Radio Direction Finding system (RDF).

Mounted on the forward face of the navigator’s radio panel was the Marconi R1155 Radio Receiver which could be tuned via the Lancaster’s Directional Finder (DF) Loop rotatable antenna to the home airfield’s transmitting frequency. The signal transmitted from the airfield was effectively a homing beacon, enabling the aircraft to follow the radio beam back to its origin.

The RDF delivered a constant signal to two visual L/R Beam Approach Indicators - one mounted above the navigator’s radio and the other atop the pilot’s main instrument panel next to the Directional Radio Compass.

The two floating, cross-hair needles of the L/R Beam Approach Indicator provided the pilot with a visual indicator of the aircraft’s position in relation to the radio transmission directing him to turn either left or right to stay on course.

This L/R Beam Approach Indicator bears the Air Ministry ‘AM & Crown’ with a Ref No: IOQ/2
