Which statement is true about Class 3 medications as it relates to flight status?

• A. They disqualify the pilot automatically
• B. They require no action
• C. They require a waiver
• D. They require a medical hold for 24 hours

Answer: (C)

Class 3 medications are those that can potentially affect a pilot’s performance but aren’t automatic disqualifiers. Because their impact varies by drug and by individual, you don’t just lose flight status outright; you go through a waiver process to determine safety.

The waiver, or special issuance, involves the aviation medical examiner reviewing why you’re taking the medication, the exact dosage, how long you’ll be on it, and any side effects that could impair flight, such as drowsiness, dizziness, or slowed reaction time. The examiner may request additional medical information or testing and might attach restrictions or a limited duration to the permission. If the underlying condition changes or you discontinue the medication, you’d be reevaluated.

Why the other ideas don’t fit: these meds aren’t automatically disqualifying, so action is required but not an automatic ban. There isn’t a universal 24-hour hold that applies to all Class 3 medications; some drugs may require a waiting period, while others may be approved with monitoring or alternative treatments. The key point is that a waiver is the route to maintain flight eligibility while using these medications.
