What does the landing gear of an aircraft include?

The landing gear of an aircraft is a critical component designed to support the aircraft during landing, takeoff, and taxiing. It typically consists of the main gear, which carries the bulk of the aircraft's weight during these phases of flight, and the nose gear, which provides stability and steering control on the ground. Additionally, the landing gear includes wheels that facilitate movement on runways and taxiways, and brakes that allow the aircraft to slow down or stop after landing.

Understanding the functionalities of the landing gear is essential for flight attendants as they may need to ensure passenger safety during the landing phase, which involves a thorough understanding of the aircraft's systems, including how the landing gear operates. The other options listed either encompass parts of the aircraft that do not relate to landing gear specifically or represent different systems critical to flight but are not part of what comprises the landing gear itself.
