  • Chapter 16: Navigation › Effect of Wind

    aircraft heading coincides with the TC and the wind is blowing from the left, the track does not coincide with the TC. The wind causes the aircraft to drift to the right, so the track falls to the right ... aircraft coincide with the desired course. If the mass of air is moving across the course from the left, the aircraft drifts to the right, and a correction must be made by heading the aircraft sufficiently to the left…

  • Chapter 2: Aeronautical Decision-Making › TEAM Checklist: Choose and Implement Risk Controls › The DECIDE Model

    than the other. Since the pilot never executed the first step of identifying which engine failed, he feathered the left engine and set the right engine at zero thrust. This essentially restricted the aircraft to a controlled glide. Upon realizing ... going to make the runway, the pilot increased power to both engines causing an enormous yaw to the left (the left propeller was feathered) whereupon the aircraft started to turn left. In desperation, the instructor closed both throttles…

  • Chapter 2: Aeronautical Decision-Making › RISK › Human Behavior

    dispatcher, Everyman neglected to complete the fuel cross-feed check before taking off. Everyman, who was flying solo, left the right-fuel selector in the cross-feed position. Once aloft and cruising, he noticed a right roll tendency and corrected ... with aileron trim. He did not realize that both engines were feeding off the left wing’s tank, making the wing lighter. After two hours of flight, the right engine quit when Everyman was flying along a deep canyon gorge…

  • Chapter 5: Aerodynamics of Flight › Basic Propeller Principles › Torque Reaction

    during the takeoff roll, an additional turning moment around the vertical axis is induced by torque reaction. As the left side of the aircraft is being forced down by torque reaction, more weight is being placed on the left main ... landing gear. This results in more ground friction, or drag, on the left tire than on the right, causing a further turning moment to the left. The magnitude of this moment is dependent on many variables. Some of these variables…

  • Chapter 5: Aerodynamics of Flight › Basic Propeller Principles › Corkscrew Effect

    This results in more ground friction, or drag, on the left tire than on the right, causing a further turning moment to the left. The magnitude of this moment is dependent on many variables. Some of these variables ... flow of the slipstream is to the right, while the yawing moment caused by torque reaction is to the left—in effect one may be counteracting the other. However, these forces vary greatly and it is the pilot’s responsibility…
