Aerodrome Ground Markings - 1928

This drawing, Y-51, shows the specifications for some of the earliest standardised aerodrome ground markings in Australia, issued by the Civil Aviation Branch. It was drawn on 28 July 1928. The figures are titled:

1. Licenced Public Aerodrome - All Types
2. Licenced Public Aerodrome - Restricted Types
3. Emergency Landing Ground - All Directions
4. Emergency Landing Ground - One Way
5. Unofficial Landing Ground
6. Markings Showing Limits of Aerodrome
7. Method of marking Swamp, Rough Ground, Undergrowth etc.
8. Method of marking Washout, Soft Ground etc.

The basic dimension of the line-type markings was 50 ft, with a 3 ft line thickness. Unusable areas were to be marked with tins, painted white and sunk so that their tops were 2 in above the surface.
