Four separate things get mixed up when people start flying. An ARN identifies you in CASA’s systems, an aviation medical deals with your health, and an ASIC or AVID deals with aviation security. None of them is a pilot licence, and none replaces another, so you collect each one for its own reason.
Checked against: CASA licensing guidance for aeroplane and helicopter pilots and the CASA Part 61 Plain English Guide, as summarised in Aero Academic’s 27 October 2026 editorial brief; instructor and aviation medical review pending before publication.
| Document | What it is for | What it is not |
|---|---|---|
| ARN (Aviation Reference Number) | Identifies you in CASA’s systems and is needed to hold a CASA licence, permission or authorisation | Not a licence, a medical or a security card |
| Aviation medical | Addresses medical fitness for the flying you intend to do | Not a security clearance and not proof you can fly |
| ASIC (Aviation Security Identification Card) | Relates to aviation security requirements, including the security-controlled airport environment | Not a pilot licence, a competency record or a medical certificate |
| AVID (Aviation Identification) | Another security-related document with its own eligibility and application conditions | Not interchangeable with an ASIC; CASA guidance says it cannot be used at security-controlled airports |
| Pathway | Beginner explanation | Watch for |
|---|---|---|
| Class 1 | The professional medical pathway to investigate for commercial and airline flying | The precise legal requirement depends on the operation |
| Class 2 | A conventional aviation medical pathway widely relevant to private flying and certain other permitted operations | Check it matches the licence you want |
| Basic Class 2 | A pathway based on the applicable Austroads commercial-driver medical standard | Eligibility conditions and operating restrictions apply |
| Class 5 self-declaration | A separate self-declaration pathway with eligibility criteria, required learning and operational limitations | It is not unrestricted medical approval, and the limits can change |
| Document being requested | Question to ask the requester |
|---|---|
| Enrolment confirmation | Does the recipient need proof of enrolment, course details or training dates? |
| Operational-need confirmation | Does the issuing body need the school to confirm why airport access is needed? |
| Flight-test recommendation | What competency evidence and instructor recommendation does the assessment need? |
| Overseas-student documentation | Which school, immigration or security process is asking for the document? |
Most people expect to start flight training by booking a lesson. In practice the first weeks can include identity checks, a medical, a security application and a stack of forms, and the vocabulary is full of three- and four-letter abbreviations. The result is a common mistake: treating everything as one “pilot clearance” that you either have or do not have.
It helps to sort the paperwork by the question each document answers. An ARN answers who you are in CASA’s systems. A medical answers whether you are fit for the flying you want to do. An ASIC or AVID answers a security question about access to aviation environments. A licence, which comes much later, answers whether you have demonstrated the knowledge and skill. Keeping those questions apart makes every conversation with a school, an examiner or CASA simpler.
This guide is general education, not individual medical advice and not a substitute for your training organisation. Requirements change, so treat the tables here as a map and confirm the live detail with CASA, your school and a Designated Aviation Medical Examiner before you spend money.
An Aviation Reference Number, or ARN, is the identifier CASA uses for you. You need an individual ARN to access CASA services and to hold a CASA licence, permission or authorisation. You will use it when you book theory exams, when a medical is lodged and when a licence application is made.
You apply through myCASA by entering your personal details and verifying your identity. CASA says an ARN can be issued within minutes after successful automatic identity verification, so this is the cheapest and fastest item on the list. There is no reason to leave it late, because other steps depend on it.
Before you submit, check that your full legal name, including any middle names, matches the identification you will use everywhere else. A name that differs between your ARN, your medical application, your exam booking and your training records is the sort of small mismatch that can delay an application for weeks. Use one consistent spelling from the first form onward.
DAME stands for Designated Aviation Medical Examiner. It is a medical practitioner designated to conduct the aviation medical examinations used in the licensing system. A routine appointment with your usual doctor is not automatically the same thing as a Class 1 or Class 2 aviation medical assessment, so do not assume a general check-up will satisfy a school.
The correct pathway depends on the flying you want to do, not simply on whether you have started lessons. If professional flying is the goal, investigate the professional medical standard before you commit to a large training package, because finding out late that a condition affects Class 1 certification is far more expensive than asking early.
A DAME is also the right first contact if you have a condition, a medication or a past medical decision you are unsure about. They can explain how it is assessed and what records are needed. That conversation is the right place to ask, not an online forum.
Australia has several medical pathways with different eligibility conditions and operating limitations, including Class 1, Class 2, Basic Class 2 and the Class 5 self-declaration arrangements. Table 2 summarises how a beginner can think about each one. The summary is deliberately general: the legal detail sits in CASA’s current guidance.
The existence of a lower pathway does not mean it will suit the aircraft, the passengers, the training or the operations you intend to do. A pathway can be valid for a recreational licence and still be too limited for the career you want later. Ask what the pathway allows, and equally what it does not allow, before you rely on it.
A note on the Class 5 self-declaration pathway: do not copy a fixed table of its restrictions from any website, including this one. A 2026 working group recommended changes to several limitations, and a recommendation is not an enacted rule. Always read the live CASA requirements on the day you decide.
Before you book, ask the examiner what records are needed for the class you are seeking and for your own medical history. Arriving with the right papers saves a second appointment.
A useful preparation checklist is below. Bring or prepare as much as applies to you.
Never stop a prescribed medication, or leave out part of your medical history, to improve the chance of certification. Doing so is unsafe and can cause far bigger problems later. Ask the aviation medical professional how the condition and the treatment should be assessed.
An ASIC, or Aviation Security Identification Card, is associated with aviation security requirements, including the security-controlled airport environment. It exists because some parts of an airport are restricted, and people who work or train there are expected to meet a security standard.
It is not a pilot licence, it is not evidence of flying competence and it is not an aviation medical certificate. Holding an ASIC says nothing about whether you can fly, just as holding a Class 2 medical says nothing about whether you may enter a restricted apron.
Do not assume that every beginner needs an ASIC before their first lesson. Whether you need one depends on the airport, the training activity and the licence application. Your flight school should explain the airport’s access arrangements and which application process applies to your circumstances, so ask them rather than guessing.
No. An Aviation Identification, or AVID, is another security-related document, but CASA’s guidance states that an AVID cannot be used at security-controlled airports. That single difference is why “get whichever is cheaper” is not a sensible way to choose between them.
The eligibility and application conditions also differ between the two, so the decision should come from where you will train and what the school requires, not from price. If you are unsure which applies to you, put the question to your training organisation in writing and keep the reply in your folder.
If you are training at a smaller aerodrome that is not security controlled, the practical position can be different from training at a large airport. That is exactly the kind of local detail a school can confirm in one email.
“Get a letter from your training organisation” is too vague to be useful. When a form, an issuing body or an examiner asks for a letter, ask them what the letter is for, then use Table 3 to see what they probably mean.
These documents should not be treated as one universal “CASA approval letter”. A flight-test recommendation, for instance, belongs to a separate assessment process described in CASA’s licensing guidance, and it depends on the instructor’s view of your competence, not on administration. An enrolment confirmation is a different thing altogether.
Asking the requester to name the purpose of the document avoids the most common failure, which is receiving a letter that is correct but is the wrong kind of letter for the form in front of you.
Create one folder, on paper, in the cloud or both, for identification, ARN details, medical documents, security correspondence, training records, exam results and assessment paperwork. You will refer to it for years, and instructors, examiners and employers all ask for items from it.
After a CASA exam, keep the Result Advice and any Knowledge Deficiency Report. A KDR is provided when the result is above 50% and below 100%, and the head of operations or an examiner may use the report to revisit the knowledge areas you missed. Our guide on KDRs explains how to read one.
Add dates to everything. A medical certificate, a recent-experience record and a flight review each have their own validity rules, and a dated folder is the quickest way to see what is due.
No. An ARN, or Aviation Reference Number, identifies you in CASA’s systems and is needed to hold a CASA licence, permission or authorisation. It does not give you any flying privileges. You apply through myCASA, and CASA says it can be issued within minutes after successful automatic identity verification.
It depends on the course and the school, and on the flying you intend to do. The appropriate pathway depends on your goal rather than on whether lessons have started. Ask your training organisation what it requires before the first lesson and speak to a Designated Aviation Medical Examiner if you are unsure.
No. An ASIC and an AVID are both security-related documents but they are not interchangeable. CASA’s guidance states that an AVID cannot be used at security-controlled airports. Eligibility and application conditions differ, so ask your training organisation which one applies to the airport and the training you plan.
Not automatically. A DAME is a medical practitioner designated to conduct aviation medical examinations. A routine general practice appointment is not automatically equivalent to a Class 1 or Class 2 aviation medical assessment. Check that the practitioner is a DAME before you book for a medical examination.
Only within its own conditions. It is a separate self-declaration pathway with eligibility criteria, required learning and operational limitations, so it is not unrestricted medical approval. Its limits may change, so confirm the live CASA requirements before you rely on it.
Speak to a Designated Aviation Medical Examiner early. Do not stop prescribed medication and do not leave out medical history to improve your chances. The examiner can explain how the condition and treatment are assessed and which reports they need.
