27.  Mission:  Describe the factors that affect aircraft performance.  Identify how aircraft weight, atmospheric conditions, runway environment, and the fundamental physical laws governing the forces can affect aircraft performance.  EQ: Describe the importance of Aeronautical Knowledge for the student pilot learning to fly. Today’s Mission Requirements

28. Takeoff Performance The effect of wind on takeoff distance is large. The effect of a headwind is to allow the aircraft to reach the lift-off speed at a lower groundspeed while the effect of a tailwind is to require the aircraft to achieve a greater groundspeed to attain the lift-off speed.

29. Takeoff Performance The effect of wind on landing distance is identical to its effect on takeoff distance.

30. Takeoff Performance The effect of proper takeoff speed is especially important when runway lengths and takeoff distances are critical. The takeoff speeds specified in the AFM/POH are generally the minimum safe speeds at which the aircraft can become airborne.

31. Takeoff Performance Any attempt to take off below the recommended speed means that the aircraft could stall, be difficult to control, or have a very low initial rate of climb.

32. Takeoff Performance Excessive airspeed at takeoff may improve the initial rate of climb and “feel” of the aircraft, but will produce an undesirable increase in takeoff distance.

33. Landing Performance The effect of gross weight on landing distance is one of the principal items determining the landing distance.

34. Landing Performance One effect of an increased gross weight is that a greater speed will be required to support the aircraft at the landing AOA and lift coefficient.

35. Landing Performance The effect of wind on landing distance is large and deserves proper consideration when predicting landing distance.

36. Landing Performance The principal effect of wind on landing distance is the change in the groundspeed at which the aircraft touches down.

37. Landing Performance The landing speeds specified in the AFM/POH are generally the minimum safe speeds at which the aircraft can be landed.

38. Landing Performance Any attempt to land at below the specified speed may mean that the aircraft may stall, be difficult to control, or develop high rates of descent.

39. Landing Performance An excessive speed at landing may improve the controllability slightly (especially in crosswinds), but causes an undesirable increase in landing distance.

40. Landing Performance The most critical conditions of landing performance are combinations of high gross weight, high density altitude, and unfavorable wind.
