The sky is no longer the exclusive domain of crewed aviation. We are witnessing a monumental era where technology is revolutionising our skies, transforming traditional industries, and unveiling unprecedented commercial opportunities for those bold enough to take flight. However, as the presence of Remotely Piloted Aircraft (RPA) becomes a staple in our national airspace, the responsibility of the remote pilot scales in equal measure.
For many aspiring professionals, the transition from a hobbyist environment to the complexities of controlled airspace can be daunting. The Civil Aviation Safety Authority (CASA) maintains rigorous standards to ensure the safety of all airspace users. Central to this safety framework is the Aeronautical Radio Operator Certificate (AROC). Operating within or near controlled zones (CTR) without the technical proficiency and legal authority provided by an AROC is not merely a procedural oversight; it is a significant risk to aviation safety.
Below, we examine the seven most common mistakes made by drone pilots in controlled airspace and how obtaining your AROC through a CASA-approved training provider can ensure you remain compliant and professional.
1. Transmitting on Aviation Frequencies Without Authority
Perhaps the most fundamental error is the assumption that holding a Remote Pilot Licence (RePL) automatically grants the right to use an air-band radio. Under CASR Part 64, transmitting on an aviation VHF frequency without an AROC or a qualifying flight crew licence is a breach of federal regulations.
An AROC is the legal instrument that authorises you to communicate with Air Traffic Control (ATC) and other pilots. Without it, you are effectively operating in a communications vacuum, unable to legally coordinate your movements in areas where two-way radio communication is mandatory. Proper education ensures that you are not just a pilot, but a legally recognised operator within the Australian aviation ecosystem.
2. Using Non-Standard Phraseology
The aviation world communicates through a precise and standardised lexicon. A common mistake among uncertified pilots is the use of “CB-style” language or casual English over the radio. In a high-stakes environment like a busy control zone, ambiguity can lead to catastrophe.
The AROC curriculum focuses heavily on Standard ICAO/CASA Phraseology. This training teaches you to deliver clear, concise, and structured messages. Instead of rambling, a certified operator follows the standard format: Who you are calling, who you are, where you are, and what your intentions are. This professional diction builds immediate credibility with ATC and ensures that your message is understood the first time, every time.
3. Confusing AGL with AMSL
In the world of drone flight, we often focus on Height Above Ground Level (AGL). However, ATC and manned aircraft operate using Altitude relative to Mean Sea Level (AMSL).
A critical mistake is informing a tower that you are at “400 feet” when you mean 400ft AGL, but the local terrain is already 300ft above sea level. To the controller, you are at 700ft AMSL, which could put you directly in the path of an approaching aircraft. AROC training provides the technical grounding to understand these vertical datums, ensuring you provide accurate data that aligns with the rest of the aviation community.
4. Failing to Obtain or Read Back Clearances
Entering controlled airspace requires an explicit clearance from ATC. A frequent hurdle for novices is the “readback” requirement. When ATC issues an instruction: such as an altitude restriction or a boundary limit: the pilot must repeat the key elements of that instruction back to the controller.
This process is a safety “closed-loop” system. Failing to read back a clearance accurately means the controller cannot be certain you have understood the instruction. Through our comprehensive RePL and AROC training, pilots practice these interactions until they become second nature, eliminating the “mic fright” that often leads to communication breakdowns.
5. Inadequate Frequency Management
Operating near an aerodrome requires a sophisticated understanding of frequency boundaries. Many pilots make the mistake of monitoring the wrong Common Traffic Advisory Frequency (CTAF) or failing to switch frequencies when moving between sectors.
Furthermore, “stepping on” another transmission: transmitting while someone else is speaking: can block critical emergency calls. AROC training teaches the discipline of “listening before you talk” and how to use documents like the ERSA (En Route Supplement Australia) to identify the correct frequencies for your specific operating area.
6. Neglecting to Identify as an RPA
When communicating on a radio, you are a “station” among many. A dangerous mistake is failing to identify your aircraft type correctly. Manned pilots need to know they are sharing the sky with a drone, as its flight characteristics and visibility are vastly different from a Cessna or a helicopter.
Using terms like “Remotely Piloted Aircraft” or “Drone” in your initial call allows other pilots to adjust their situational awareness. It is a hallmark of a professional operator to be transparent about the nature of their mission, fostering a culture of mutual respect and safety between crewed and uncrewed aviation.
7. The Absence of a Continuous Listening Watch
The final mistake is treating the radio as a one-way tool for your own benefit. Even if you do not intend to speak, if your operation requires a radio, you must maintain a continuous listening watch.
Many pilots miss vital information: such as an inbound emergency medical helicopter or a change in runway direction: because they have the volume turned down or are distracted. An AROC emphasises that the radio is your most important sensory tool for “seeing” beyond your line of sight.
The Path to Professionalism
Challenges in the aviation industry are not barriers; they are hurdles to be overcome through proper education and a commitment to excellence. By mastering the art of aeronautical radio, you transition from being a “drone flyer” to a respected “aviation professional.”
Whether you are looking to start a career through our Certificate III in Aviation or seeking to expand your commercial capabilities with a Job-Ready Drone Program, the AROC is an essential component of your toolkit.
