  Chapter 2: Aerodynamics of Flight › Airflow and Reactions in the Rotor Disk › Rotational Relative Wind (Tip-Path Plane)

  Airflow and Reactions in the Rotor Disk Relative Wind Knowledge of relative wind is essential for an understanding of aerodynamics and its practical flight application for the pilot. Relative wind is airflow relative to an airfoil. Movement of an airfoil ... through the air creates relative wind. Relative wind moves in a direction parallel to but opposite of the movement of the airfoil. [Figure 2-15] There are two parts to wind passing a rotor blade: • Horizontal part—caused…

  Chapter 3: The Learning Process › Errors › Learning from Error

  Error Recovery Given that the occasional error is inevitable, it is a worthwhile exercise to practice recovering from commonly made errors, or those that pose serious consequences. All flight learners need to learn and practice a lost procedure to ensure ... which they have lost their way. It is useful to devote the same sort of preparation to other common learner errors. Learning from Error Error can be a valuable learning resource. Learners naturally make errors, which instructors can utilize…

  Chapter 6: Threat and Error Management Introduction Threats What is an Error? Causes of Errors Insufficient Training & Experience Introduction Pilots use risk management as described in earlier chapters to analyze the likelihood and potential severity of an incident or accident ... encounter unforeseen hazards or threats. In addition, a pilot may respond inappropriately to a given condition, thus making an error. This chapter provides strategies pilots may use once flight begins. Threats Threats have the following characteristics: • Threats occur outside…

  preferred, but rearward flight may be necessary, stopping often while moving to check on the location of obstacles relative to the tail rotor. When planning the takeoff, consider the direction of the wind, obstructions, and forced landing areas. To help ... power setting and accelerate to the normal climb speed. Then, reduce power to the normal climb power setting. Common Errors 1. Failure to perform, or improper performance of, a high or low reconnaissance. 2. Approach angle that is too steep…

  Acceleration-North/Deceleration-South) may help you to remember the acceleration error. [Figure 8-37] Acceleration causes an indication toward north; deceleration causes an indication toward south. Figure 8-37. The effects of acceleration error. Oscillation Error Oscillation is a combination ... errors previously mentioned and results in fluctuation of the compass card in relation to the actual heading direction of the aircraft. When setting the gyroscopic heading indicator to agree with the magnetic compass, use the average indication between the swings…

  landing carriage, slowing the helicopter; however, this is dependent on the condition of the landing surface. One common error is the holding of the helicopter off the surface, versus cushioning it onto the surface during an autorotation. Holding the helicopter ... surface for a controlled, smooth landing instead of allowing the helicopter to drop the last few inches. Common Errors 1. Not understanding the importance of an immediate entry into autorotation upon powerplant or driveline failure. 2. Failing to use sufficient…
