Which are categories of aircraft under airman certification?

• A. Airplane, Rotorcraft, Glider, Lighter than Air
• B. Jet, Balloon, Submarine, Boat
• C. Bicycle, Motorcycle, Carriage, Aircraft carrier
• D. Fixed-wing, Rotary-wing, Balloon, Submarine

Answer: (A)

The key idea is how airman certificates organize aircraft by the way they generate lift and operate. There are four official categories: airplane, rotorcraft, glider, and lighter-than-air. An airplane is a fixed-wing powered aircraft, a rotorcraft uses rotating blades (like a helicopter or similar), a glider flies with wings and may be towed or self-launched without a powerplant, and lighter-than-air aircraft obtain lift from buoyancy (balloons and airships).

So the best choice lists these exact groups: Airplane, Rotorcraft, Glider, Lighter than Air. This matches the official categories pilots are certified in. The other options mix in non-aircraft items (submarine, boat), use nonstandard or incomplete terms, or combine categories in a way that doesn’t reflect how airman certificates are organized (for example, treating fixed-wing or balloon as separate primary categories or including something like a submarine).
