5 crossbars centre line with 3 2 and 1 lamp per light unit.

Img794in 1946 mr e s calvert of the royal aircraft establishment farnborough was requested by a uk ministry of civil aviation airfield lighting committee to investigate the problem of approach lighting and establish the general principles involved calvert tackled the problem by attempting to ascertain the visual and mental processes by which a pilot lands an aircraft he then developed a theoretical model by which different lighting systems could be compared and tested his theoretical results using simulationcalvert's line of reasoning led him to the conclusion that to provide smooth transition from instrument to visual flying without optical illusions and to provide sensitive and natural indications which could easily be interpreted by the average pilot the approach lighting pattern should consist of a centre line of light with horizontal bars of light running transversely across it at even intervals this pattern consists of two basic elements a line of lights leading to the runway threshold and horizontal lights to define the attitude of the aircraft 795diagrams above with horizon bars the pilot can see if he is on an even keel left or banked right wing down to turn on to the centre line right
