  Chapter 11: Aircraft Performance › Performance › Straight-and-Level Flight

  Straight-and-Level Flight All of the principal components of flight performance involve steady-state flight conditions and equilibrium of the aircraft. For the aircraft to remain in steady, level flight, equilibrium must be obtained by a lift equal ... aircraft weight and a powerplant thrust equal to the aircraft drag. Thus, the aircraft drag defines the thrust required to maintain steady, level flight. As presented in Chapter 4, Aerodynamics of Flight, all parts of an aircraft contribute…

  Landing behind a larger aircraft- when parallel runway is closer than 2,500 feet. Consider possible drift to your runway. Stay at or above the larger aircraft’s final approach flight path- note its touchdown point. 3. Landing behind ... larger aircraft- crossing runway. Cross above the larger aircraft’s flight path. 4. Landing behind a departing larger aircraft- same runway. Note the larger aircraft’s rotation point-land well prior to rotation point. 5. Landing behind a departing larger…

  Chapter 7. Safety of Flight › Section 4. Wake Turbulence › 7-4-3. Vortex Strength

  Vortex Strength a. Weight, speed, wingspan, and shape of the generating aircraft’s wing all govern the strength of the vortex. The vortex characteristics of any given aircraft can also be changed by extension of flaps or other wing configuring ... devices. However, the vortex strength from an aircraft increases proportionately to an increase in operating weight or a decrease in aircraft speed. Since the turbulence from a “dirty” aircraft configuration hastens wake decay, the greatest vortex strength occurs when…

  Chapter 5: Aerodynamics of Flight › Axes of an Aircraft

  Whenever an aircraft changes its flight attitude or position in flight, it rotates about one or more of the three axes. [Figure 5-18] The aircraft’s motion about its longitudinal axis resembles the roll of a ship from side ... side. In fact, the names used to describe the motion about an aircraft’s three axes were originally nautical terms. They have been adapted to aeronautical terminology due to the similarity of motion of aircraft and seagoing ships. The motion…

  Chapter 5: Aerodynamics of Flight › Aircraft Design Characteristics › Longitudinal Stability (Pitching)

  Negative dynamic stability—over time, the motion of the displaced object increases and becomes more divergent. Stability in an aircraft affects two areas significantly: • Maneuverability—the quality of an aircraft that permits it to be maneuvered easily and to withstand ... stresses imposed by maneuvers. It is governed by the aircraft’s weight, inertia, size and location of flight controls, structural strength, and powerplant. It too is an aircraft design characteristic. • Controllability—the capability of an aircraft to respond…

  Airplane—an engine-driven fixed-wing aircraft heavier than air, that is supported in flight by the dynamic reaction of the air against its wings. • Glider—a heavier-than-air aircraft, that is supported in flight by the dynamic reaction ... against its lifting surfaces and whose free flight does not depend principally on an engine. • Lighter-than-air aircraft—an aircraft that can rise and remain suspended by using contained gas weighing less than the air that is displaced…
