What are the two flight conditions?

• A. Level, Climbing
• B. Steady, Unsteady
• C. Balanced, Unbalanced
• D. Hovering, Translational

Answer: (C)

Two flight conditions are balanced flight and unbalanced flight. Balanced flight means the forces and moments acting on the aircraft are in equilibrium, so there is no net acceleration or change in attitude. Lift and thrust exactly counter weight and drag, allowing straight-and-level flight, a steady climb or descent, or hover when rotor thrust matches weight. Unbalanced flight occurs when there is a net force or moment, causing the aircraft to accelerate in translation or rotate, leading to changes in speed, altitude, or orientation during maneuvers. The other options describe aspects of the flight path or motion steadiness rather than the fundamental equilibrium state of the aircraft.
