What are the three basic problems of flight?

The three basic problems of flight revolve around the fundamental challenges that aircraft must overcome in order to achieve and maintain flight. Developing necessary lift is crucial as it allows an aircraft to ascend from the ground and become airborne. This involves creating sufficient aerodynamic forces through the shape and angle of the wings relative to the airflow.

Sustaining that lift is equally important once the aircraft is airborne, as it ensures the aircraft can maintain altitude and stable flight. This requires careful management of the aircraft's speed and angle of attack, as well as addressing factors such as weight and environmental conditions.

Controlling the aircraft once it is flying captures the essence of maneuverability in flight, which involves using various controls such as ailerons, elevators, and rudders to change direction, altitude, and speed safely and effectively. This aspect of flight control is essential for navigation and ensuring the safety of the aircraft and its occupants.

In contrast, while the other choices mention relevant concepts related to flight, they do not encapsulate the core challenges addressed by the selected answer. Lift, drag, and weight pertain more to the forces acting on the aircraft rather than the problems of flight itself. Speed, altitude, and control focus on performance parameters rather than the fundamental tasks needed for flight. Navigation
