Which of the following is NOT one of the basic components of fixed-wing aircraft?

The basic components of fixed-wing aircraft include wings, fuselage, and landing gear. The wings are critical because they generate lift, the fuselage houses the crew and cargo, and the landing gear supports the aircraft during takeoff and landing.

A rotor, however, is associated with rotary-wing aircraft, such as helicopters. It is designed to create lift by rotating around a vertical axis, allowing the aircraft to hover, take off, and land vertically. Since fixed-wing aircraft do not utilize rotors for their flight operations, this makes it the correct answer to identify what is not a basic component of fixed-wing aircraft.
