Australian civil air ensign

The design of the flag is based on the British civil air ensign, which is divided into quarters by a dark blue cross with a white fimbriation.When an Australian version was first adopted in 1935, it included the stars from the Australian national flag in yellow, and with the Southern Cross rotated by roughly 45 degrees, meaning that the smallest star was completely inside the arm of the blue cross.In 1948, the colour of the stars was changed to white to improve the flag's recognition when viewed from a long distance.Originally, civil air ensigns were intended to be flown at airports and by civilian aircraft on the ground.On 21 April 2009, the Civil Aviation Safety Authority granted the Australian Air League official use of the Australian civil air ensign to recognise the organisation's significant contribution to aviation in Australia.
