Where is the leading edge located?

The leading edge refers to the front edge of an aircraft's wing, which is the part that first comes into contact with the airflow as the aircraft moves forward. This section is crucial for generating lift and is typically shaped to optimize aerodynamic performance. Understanding the position of the leading edge is fundamental for flight attendants as well, since it relates to the overall design and performance capabilities of the aircraft they serve on. The leading edge's design, including any devices like slats or flaps, helps control airflow over the wing, which is vital during various phases of flight, including takeoff and landing.

The other options refer to different parts of the aircraft, such as the back of the wing, the fuselage, and the tail, which do not describe the leading edge accurately. Each of these areas serves distinct functions that are important for aircraft operations but do not pertain to the leading edge of the wing itself.
