CASA AROC cheat sheet

In Australia, an aeronautical radio operator qualification is issued under the radiocommunications framework administered by ACMA; the CASA AROC is the aviation competency certificate that supports the associated flight crew radio privileges.

An AROC is required for flight crew who operate radio equipment on frequencies allocated to aeronautical mobile services; operations without the required qualification breach both aviation and radiocommunications obligations.

Application requires proof of identity, completion of an approved training course or recognised equivalent, and a passed assessment conducted by a CASA-approved or delegated assessor.

The assessment record must be retained by the issuing organisation and produced on request by CASA or an authorised officer; applicants should keep a copy of the certificate and assessment record.

Certificates are issued without an expiry date in most cases, but privileges may be suspended or cancelled for safety-related or regulatory breaches.

Name or address changes must be notified to the issuing authority so the register of qualified operators remains accurate.

Overseas or military qualifications may be recognised through a CASA assessment of equivalence; the applicant must still demonstrate knowledge of Australian radiotelephony procedures and local frequency usage.

Applications are typically processed through a CASA-approved testing officer or an approved training provider; direct applications to CASA are not the normal pathway for a first issue.

Training must cover radio theory, frequency bands, phraseology, emergency procedures, and regulatory obligations; assessment must verify both knowledge and practical radiotelephony performance.

The practical assessment typically includes simulated or live transmissions using standard phraseology, readback of clearances, and handling of abnormal and emergency situations.

Assessors must hold the appropriate delegation or approval and must document the assessment outcome, including any conditions or limitations placed on the qualification.

Candidates must demonstrate competency in standard calls: departure, position reporting, clearance readback, and distress and urgency calls.

Knowledge assessment covers frequency allocation, licence conditions, radio failure procedures, and interference reporting obligations.

Recency of training is not mandated by the AROC itself, but operators must maintain competence through ongoing operational experience and, where required, recurrent training.

Assessment records must be retained and made available for audit; falsification of assessment records is a serious breach of both aviation and radiocommunications rules.

Remedial training must be completed before re-assessment if a candidate fails a component; a failed attempt cannot be recorded as a pass.

Standard phraseology from the ICAO and Australian radiotelephony procedures must be used; plain language is permitted only when standard phraseology is inadequate.

Readback is mandatory for clearances, runway instructions, altitude instructions, heading instructions, and frequency changes that affect separation or safety.

Distress calls use MAYDAY, repeated three times, preceded by the station identification; urgency calls use PAN PAN, repeated three times.

Radio failure procedures: squawk 7600, attempt contact on the last assigned frequency, then on the emergency frequency 121.5 MHz, and follow the published lost-communication procedure.

Position reports include aircraft identification, position, time, altitude, and next position with estimated time; the standard format follows the order in the procedures document.

Frequency change instructions must be read back and the new frequency confirmed before leaving the previous frequency.

Emergency frequency 121.5 MHz is monitored where required; unauthorised transmissions on 121.5 are prohibited except for genuine distress, urgency, or safety communications.

The phonetic alphabet and standard word spelling must be used for identification of letters and unclear items; numbers are transmitted using standard group pronunciation.

The AROC confers the privilege to operate radiocommunications equipment on aeronautical frequencies for flight safety purposes, subject to the conditions of the associated licence.

Operators must not transmit false or misleading distress, urgency, or safety signals; doing so is an offence under radiocommunications and aviation legislation.

Operators must maintain a listening watch on the assigned frequency and must not cause harmful interference to other stations.

Communications must be limited to matters relating to flight safety and the efficient operation of the aircraft; personal or commercial traffic is prohibited.

Records of radio communications, where required, must be retained and produced on request by an authorised officer.

Operators must comply with directions from air traffic control and must report any radio failure or communications irregularity to the appropriate authority.

The regulatory framework includes the Radiocommunications Act, the Civil Aviation Act and associated regulations, and CASA advisory publications on radiotelephony procedures.

Breaches may result in suspension or cancellation of the qualification, fines, or prosecution; operators are responsible for ensuring their knowledge of current procedures remains up to date.
