Moorabbin Airport opened for business on the 5th of December, 1949, and by 2009 was the third busiest airport in Australia, behind Jandakot (YPJT) in Perth and Bankstown (YSBK) in Sydney.
In 2009 Moorabbin officially had 310,550 aircraft movements, and having flown out of Moorabbin a number of times I can believe this figure!!
Moorabbin generally has parallel runway operations in progress, either:
R35 LEFT and R35 RIGHT
R17 LEFT and R17 RIGHT
R31 LEFT and R31 RIGHT
R13 LEFT and R13 RIGHT
Moorabbin also has a short R22 or R04 however operations are restricted on this runway.
Runway operations are determined by prevailing wind, weather and air traffic considerations and any combination of runways may be used at any time however preference is given for 35/17 and 31/13.
