Operations at non-controlled aerodromes
A non-controlled aerodrome is an aerodrome in non-controlled airspace, also known as ‘Class G’ airspace.
Some non-controlled aerodromes host a huge diversity of aircraft. At any time, this mix might include larger passenger aircraft, general aviation aircraft and light sport aircraft.
A new resource booklet, Be heard, be seen, be safe, has been produced on radio procedures in non-controlled airspace. Radio must always be used in conjunction with safe ‘see-and-avoid’ procedures. First and foremost, this means scanning with your eyes, including above you and below you, to look out for aircraft. You must also understand how to operate safely around other aircraft types through safe separation distances and collision avoidance techniques.
Be heard, be seen, be safe, can also be ordered as a physical copy at the CASA Online Store.
Guidance and resources
We have developed guidance material for efficient and effective radio calls, with the aim of making sure the procedures are easy to follow and pilots are correctly following the advice for safe operations.
The following information will help pilots operate aircraft safely at, or in the vicinity of, non-controlled aerodromes.
