In page Croydon Airport:

"

Croydon returned to civil control in February 1946; a diagram in the issue of Flight magazine dated 11 April shows 1,250 yards (1,140 m) ground run in the 170–350 direction, 1,150 yards (1,050 m) 060-240 and 1,100 yards (1,000 m) 120–300 (the numbers are degrees clockwise from north). Northolt opened to the airlines soon after that, cutting Croydon's traffic, but the September 1946 ABC Guide shows 218 departures a week to Belfast, Dublin, Liverpool, Manchester, Glasgow (Renfrew), Jersey, Guernsey, and several continental airports. A year later there were 56 departures a week, mostly BEA de Havilland Dragon Rapides that weeks later left Croydon for good.[citation needed]
