  Chapter 8: Flight Instruments › Compass Systems › Magnetic Compass Induced Errors

  Figure 8-36. Northerly and southerly turning errors. Southerly Turning Errors When turning in a southerly direction, the forces are such that the compass float assembly lags rather than leads. The result is a false southerly turn indication. The compass ... float assembly, should be allowed to pass the desired heading prior to stopping the turn. As with the northerly error, this error is amplified with the proximity to either magnetic pole. To correct this lagging error, the aircraft should…

  highest. As blade speed decreases nearer the center of the disk, downward velocity is less. Figure 2-19. Rotational relative wind. Resultant Relative Wind The resultant relative wind at a hover is rotational relative wind modified by induced flow. This ... inclined downward at some angle and opposite the effective flightpath of the airfoil, rather than the physical flightpath (rotational relative wind). The resultant relative wind also serves as the reference plane for development of lift, drag, and total aerodynamic force…

  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…

  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…

  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.

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…
