most aircraft, this is the power-off stall speed at the maximum takeoff weight in the clean configuration (gear up, if retractable, and flaps up). • Upper limit of green arc (VN0)—the maximum structural cruising speed. Do not exceed this ... speed except in smooth air. • Yellow arc—caution range. Fly within this range only in smooth air and then only with caution. • Red line (VNE)—never exceed speed. Operating above this speed is prohibited since it may result in damage…

The maximum speed at which an airplane can be safely flown with the landing gear extended. VLO. Landing gear operating speed ... maximum speed for extending or retracting the landing gear if using an airplane equipped with retractable landing gear. VLOF. Lift-off speed. The speed at which the aircraft departs the runway during takeoff. VMC. Minimum control airspeed. This…

Chapter 10: Performance Maneuvers › Lazy Eight
Poor flight control coordination 10. Stalling at any point during the maneuver 11. Execution of a steep turn instead of a climbing maneuver 12. Not scanning for other traffic during the maneuver 13. Performing by reference to the flight instruments ... rather than visual references Performance maneuvers are used to develop a pilot’s skills in coordinating the flight control’s use and effect while enhancing the pilot’s ability to divide attention across the various demands of flight. Performance maneuvers…

Chapter 5: Aerodynamics of Flight › High Speed Flight › Subsonic Versus Supersonic Flow
Compressibility (and to a lesser extent viscosity) is of paramount importance at speeds approaching the speed of sound. In these speed ranges, compressibility causes a change in the density of the air around an aircraft. During flight, a wing produces ... lift by accelerating the airflow over the upper surface. This accelerated air can, and does, reach sonic speeds even though the aircraft itself may be flying subsonic. At some extreme AOAs, in some aircraft, the speed of the air over…
