  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 1: Risk Management and Single-Pilot Resource Management › Single-Pilot Resource Management (SRM) › Task Management

  task is a function performed by a human, as opposed to one performed by a machine (e.g., setting the target heading in the autopilot). The flight deck is an environment in which important tasks compete for pilot attention ... given time. TM determines which tasks the pilot(s) should attend to. TM entails initiation of new tasks; monitoring of ongoing tasks to determine their status; prioritization of tasks based on their importance, status, urgency, and other factors; allocation…

  Chapter 9: Basic Flight Maneuvers › Hovering › Common Errors

  Common Errors 1. Tenseness and slow reactions to movements of the helicopter. 2. Failure to allow for lag in cyclic and collective pitch, which leads to overcontrolling. It is very common for a student to get ahead of the helicopter…

  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 11: Helicopter Emergencies and Hazards › Autorotation › Common Errors

  Common Errors The following common errors should be prevented: 1. Entering the maneuver at an improper altitude or airspeed. 2. Entering the maneuver without a level attitude (or not in coordinated flight). 3. Entering the maneuver and not correcting from ... descent on entry. 5. Improper use of anti-torque on entry. 6. Failure to establish the appropriate crosswind correction, allowing the aircraft to drift. Failure to maintain coordinated flight through the tum. Failure to maintain rotor rpm within…

  Chapter 7, Section I: Airplane Basic Flight Maneuvers › Turns › Steep Turns

  During training in steep turns, as in any other maneuver, attend to the most important tasks first. Keep the pitch attitude relatively constant, and more time can be devoted to cross-check and instrument interpretation. During recovery from steep turns ... released and power decreased. The common errors associated with steep turns are the same as those discussed later in this section. Remember, errors are more exaggerated, more difficult to correct, and more difficult to analyze unless rates of entry…
