Which class requires a waiver due to not currently authorized or prohibited?

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

Answer: (A)

The main idea here is how waivers come into play when a pilot isn’t currently authorized for full flight duties, but isn’t permanently disqualified. The class that covers that provisional status—where a waiver can allow flight while a temporary or conditional issue is reviewed—is the one used for private-pilot type operations. That’s why this option is the best fit: it acknowledges a not-currently-authorized or not-yet-prohibited situation that may require a medical waiver to fly. The other classes imply either full current authorization for more advanced operations or a different, non-waiver-related framework, so they don’t fit the scenario as directly.
