Sydney
Approach Control Centre -
Late 1950s
This September 1956 photo shows the Sydney Arrivals controller sitting
at the then-new Semi-automatic Level Assignment Board (SLAB). Using a
system of different coloured lights activated by the inserting or removing
of a flight progress strip, the SLAB allowed the silent coordination of
level assignment for arriving aircraft between Arrivals and the Tower.
