Which class is not currently authorized (or prohibited) and requires a waiver?

• A. Class 1
• B. Class 2
• C. Class 4
• D. Class 3

Answer: (D)

The idea here is how waivers work in aeromedical certification: when a pilot isn’t automatically authorized due to a medical issue, a formal waiver process can allow operation if safety can be shown and ongoing monitoring is arranged. Class 3 (the general aviation medical certificate) is the one that fits this situation best, because it represents the level where pilots can still fly with a waiver after evaluation, rather than being automatically restricted by the stricter standards of the other classes. Higher classes (airline or commercial) have more stringent, often non-waivable requirements, and Class 4 isn’t a standard category in this framework. So Class 3 is the option that aligns with needing a waiver to operate when not currently authorized.
