Aeromedical Certification Reference

Look up a condition to see the CASA fit-for-certification thresholds, the waiting periods after an event, when to refer to a DAME, and whether it rules out a Class 5 self-declaration. Built from the CASA Guidelines for Medical Assessment for Aviation.

Educational quick-reference, not a substitute for the full Guidelines, the CASA Clinical Practice Guidelines, or a DAME's individual assessment. Thresholds are summarised and change over time — confirm the current standard before relying on it. Certification decisions rest with CASA and the DAME.

⚠ Class 1/2/3 vs Class 5. Most thresholds below describe when a person is fit for certification (a DAME judgement for Class 1/2/3) or must be referred before certification. Class 5 is a pilot self-declaration with a fixed excluded-conditions list — where a condition is on that list, the card flags it. For the patient-facing Class 5 eligibility checker, see the CASA aviation medical guide.

How to read the cards

FIT POSSIBLE
May be certified if the listed criteria are met. Often still a DAME assessment for Class 1/2/3.

REFER FIRST
Self-declaration / automatic issue unavailable until a medical practitioner or DAME assesses.

CLASS 5 EXCLUDED
On the fixed Class 5 self-declaration excluded list — needs a DAME pathway.

General principles (CASA)

CASA's aeromedical framework is built around preventing three things: acute incapacitation (sudden, total — e.g. seizure, syncope, MI), subtle impairment (insidious cognitive or sensory decline the pilot may not notice — e.g. hypoxia interacting with cardiovascular or neurological disease), and the risk from undifferentiated conditions where the cause and prognosis aren't yet clear. A blackout of undetermined cause is treated more cautiously than a clearly identified simple vasovagal faint, because the unpredictability is the hazard. The flight environment itself adds stressors — mild hypoxia above 10,000 ft, pressure change, G-forces, dehydration, heat — that can convert a "stable on the ground" condition into an in-flight event.

For the GP, not the DAME

You don't need to be a DAME to use this. The common scenarios where a regular GP is involved:

A patient mentions they fly recreationally and you've just diagnosed something or started a medication — this tells you whether their Class 5 is now invalid and they need to stop flying / see a DAME.
A patient asks "will my heart attack / AF / new BP tablet stop me flying?" — the cards give the waiting period and the criteria.
You're doing a Basic Class 2 assessment against the Austroads commercial standard and want the aviation context.

If a patient holds a Class 1/2/3 certificate, the primary reporting obligation under Part 67 sits with the pilot — but encourage them to notify CASA and their DAME of any new relevant condition or treatment.
