UNICOM Adelaide and CA/GRS Radio Services
UNICOM Adelaide and CA/GRS Radio Services
There is a moment at every growing regional airport when pilots relying purely on sea and avoiding procedures start to feel the strain of increasing traffic. That moment is exactly when a formal radio coordination service becomes worth considering, and it is why Oz Airports offers UNICOM Adelaide and Certified Air Ground Radio Service support to South Australian aerodromes approaching this threshold.
Recognising When More Coordination Is Needed
The Civil Aviation Safety Authority monitors risk at key regional airports through periodic aeronautical studies. As traffic and risk increase, CASA may recommend introducing a formal air traffic service, ranging from:
- A Certified Air Ground Radio Service
- Full air traffic control delivered by Airservices Australia
Knowing where your Adelaide aerodrome sits against these benchmarks helps determine the right level of service before risk becomes a genuine safety concern.
UNICOM Adelaide for Events and Surge Activity
Our UNICOM Adelaide services are commonly engaged around events such as air shows, fly ins, race meetings and other occasions where activity briefly spikes well above normal levels. UNICOM is a non ATS radio communication service delivered on the common traffic advisory frequency, adding useful information on top of what pilots already share at a non controlled aerodrome.
Message types available through a UNICOM service are specific and limited, covering things like:
- Confirmation of the correct CTAF
- General aerodrome weather reports
- Aerodrome information
- Estimated arrival and departure times
- Passenger and refuelling requirements
- Parking arrangements
- Unscheduled landings
UNICOM does not direct traffic separation. Instead, it supports pilots in maintaining their own separation with better information. Our UNICOM Adelaide staff are highly experienced former air traffic controllers and flight service operators, and every service is delivered in compliance with Civil Aviation Regulation 83(2).
Certified Air Ground Radio Service Adelaide
Aerodromes with aircraft movements exceeding twenty thousand per year often reach the point where a Certified Air Ground Radio Service Adelaide deployment makes sense. A CA/GRS provides:
- Frequency confirmation for aircraft in the area
- Traffic information for known aircraft within terminal airspace
- Aerodrome weather updates
- Emergency services alerting where needed
The operator helps pilots arrange alerts, see and avoid separation, without directing that separation themselves.
Establishing full air traffic control at a regional airport can cost millions of dollars each year, costs that ultimately flow through to air operators and can restrict access for smaller users such as flying schools. A CA/GRS reduces risk without these downsides, and costs are typically recovered through a small passenger ticketing surcharge rather than direct charges to general aviation users.
CTAF Radio Services Adelaide Pilots Depend On
Whether delivered through UNICOM or CA/GRS, our CTAF Radio Services Adelaide aerodromes are built on clear, consistent communication. Pilots receive accurate information well before they are within visual range of other traffic, which is especially valuable at busy regional airports supporting training, charter and agricultural operations.
A Service Built on Genuine Aviation Experience
Oz Airports has extensive history delivering both UNICOM and CA/GRS services nationally. Our National Manager for Operations worked directly with CASA to help develop the CA/GRS service and its regulatory framework through trials at Wagga Wagga, Uluru and Broome. The service has since operated successfully at Broome, Uluru and Ballina.
Our operators are CASA licensed to deliver CA/GRS services under the Manual of Standards Part 139, and every team member brings direct air traffic control or flight service background to the role.
Backed by Veteran Discipline
As a veteran owned and operated business recognised under the Australian Veteran Owned Business initiative, Oz Airports applies the same discipline our team carried through prior aviation careers to every radio service we deliver. Adelaide operators engaging a safety critical communication service can take confidence from that background.
Frequently Asked Question
How do I know if my Adelaide aerodrome needs UNICOM or CA/GRS?
This generally depends on aircraft movement numbers and any risk findings from a CASA aeronautical study. UNICOM commonly suits short term or event based needs, while CA/GRS suits aerodromes with consistently higher traffic.
Does a CA/GRS replace the need for air traffic control?
In many cases, yes. A CA/GRS can meaningfully reduce risk at a fraction of the cost of establishing full air traffic control, though the appropriate service depends on the specific aerodrome.
Can UNICOM be arranged for a single event?
Yes. UNICOM is frequently used for events such as fly-ins and air shows, providing temporary enhanced coordination for the duration of the activity.
Who operates the radio for Oz Airports services?
Our operators have backgrounds as air traffic controllers or flight service specialists, and are CASA licensed where the service requires it.
Is CA/GRS expensive for general aviation users?
Generally no. Costs are typically recovered through a small passenger ticketing surcharge, meaning general aviation users are not directly charged.
