 The 4 forces acting on an airplane in flight are lift, weight, thrust, and drag When are the 4 forces that act on an airplane in equilibrium? During unaccelerated flight The term "angle of attack" is defined as the angle between the wing chord line and the relative wind What is the relationship of life, drag, thrust, and weight when the airplane is in straight-and-level flight? Lift equals weight and thrust equals drag One of the main functions of flaps during approach and landing is to increase the angle of descent without increasing airspeed What is one purpose of wing flaps? To enable the pilot to make steeper approaches to a landing without increasing the airspeed The angle of attack at which an airplane wing stalls will remain the same regardless of gross weight What is ground effect? The result of interference of the surface of the Earth with the airflow patterns about an airplane. Floating caused by the phenomenon of ground effect will be most realized during an approach to land when at less than the length of the wingspan above the surface What must a pilot be aware of as a result of ground effect? Induced drag decreases; therefore, any excess speed at the point of flare may cause considerable floating Ground effect is most likely to result in which problem? Becoming airborne before reaching recommended takeoff speed Which statement relates to Bernoulli's principle? Air traveling faster over the curved upper surface of an airfoil causes lower pressure on the top surface Changes in the center of pressure of a wing affect the aircraft's aerodynamic balance and controllability An airplane said to be inherently stable will require less effort to control What determines the longitudinal stability of an airplane? The location of the CG with respect to the center of lift What causes an airplane (except a T-Tail) to pitch nosedown when power is reduced and controls are not adjusted? The downwash on the elevators from the propeller slipstream is reduced and elevator effectiveness is reduced What is the purpose of the rudder on an airplane? To control yaw An airplane has been loaded in such a manner that the CG is located aft of the aft CG limit. One undesirable flight characteristic a pilot might experience with this airplane would be difficulty in recovering from a stalled condition Loading an airplane to the most aft CG will cause the airplane to be less stable at all speeds In what condition must an aircraft be placed in order to spin? Stalled During a spin to the left, which wing(s) is/are stalled? Both wings are stalled In what flight condition is torque effect the greatest in a single-engine airplane? Low airspeed, high power, high angle of attack The left turning tendency of an airplane caused by P-factor is the result of the propeller blade descending on the the right, producing more thrust than the ascending blade on the left When does P-factor cause the airpland to yaw to the left? When at high angles of attack The amount of excess load that can be imposed on the wing of an airplane depends upon the speed of the airplane Which basic flight maneuver increases the load factor on an airplane as compared to straight-and-level flight? turns What force makes an airplane turn? The horizontal component of lift During an approach to a stall, an increases load factor will cause an airplane to stall at a higher airspeed The most important rule to remember in the event of a power failure after becoming airborne is to immediately establish the proper gliding attitude and airspeed What are the 4 flight fundamentals involved in maneuvering an aircraft? straight-and-level flight, turns, climbs, and descents
