Ace the 2026 DAM Aeromedical Orientation Test – Soar High and Master the Skies!

In aeromedical practice, medications are grouped by how safely they allow someone to operate an aircraft. The highest level, Class 4, is reserved for drugs that cause significant impairment with no safe exception. These medications can produce strong CNS effects, unpredictable performance changes, or risks that make flying unsafe at any time, so certification is mandatorily disqualified if a person is taking them. Other classes may allow flight eligibility to be re-evaluated after stopping the medication or following a review, but Class 4 carries a blanket disqualification.
