반응형 Airplane Flying Handbook_old30 AFH Chapter 4-21 Elevator Trim Stall Elevator Trim Stall The elevator trim stall demonstration shows what can happen when the pilot applies full power for a go-around without maintaining positive control of the airplane. This is a demonstration-only maneuver; only flight instructor applicants may be required to perform it on a practical test. However, all pilots should be familiar with the situations that can cause an elevator trim.. 2022. 5. 19. AFH Chapter 4-20 Cross Control Stall Cross-Control Stall The objective of the cross-control stall demonstration is to show the effects of uncoordinated flight on stall behavior and to emphasize the importance of maintaining coordinated flight while making turns. This is a demonstration-only maneuver; only flight instructor applicants may be required to perform it on a practical test. However, all pilots should be familiar with the .. 2022. 5. 11. AFH Chapter 4-19 Accelerated Stalls Accelerated Stalls The objectives of demonstrating an accelerated stall are to determine the stall characteristics of the airplane, experience stalls at speeds greater than the +1G stall speed, and develop the ability to instinctively recover at the onset of such stalls. This is a maneuver only commercial pilot and flight instructor applicants may be required to perform or demonstrate on a pract.. 2021. 12. 30. AFH Chapter 4-18 Full Stalls, Power-On Full Stalls, Power-On Power-on stall recoveries are practiced from straight climbs and climbing turns (15° to 20° bank) to help the pilot recognize the potential for an accidental stall during takeoff, go around, climb, or when trying to clear an obstacle. Airplanes equipped with flaps or retractable landing gear should normally be in the takeoff configuration; however, power-on stalls should al.. 2021. 12. 29. AFH Chpater 4-17 Full Stalls, Power-Off Full Stalls, Power-Off The practice of power-off stalls is usually performed with normal landing approach conditions to simulate an accidental stall occurring during approach to landing. However, power-off stalls should be practiced at all flap settings to ensure familiarity with handling arising from mechanical failures, icing, or other abnormal situations. Airspeed in excess of the normal appr.. 2021. 12. 28. AFH Chapter 4-16 Approaches to Stalls (Impending Stalls), Power‑On or Power-Off Approaches to Stalls (Impending Stalls), Power‑On or Power-Off An impending stall occurs when the airplane is approaching, but does not exceed the critical AOA. The purpose of practicing impending stalls is to learn to retain or regain full control of the airplane immediately upon recognizing that it is nearing a stall, or that a stall is likely to occur if the pilot does not take appropriate ac.. 2021. 12. 27. AFH Chapter 4-15 Stall Training Stall Training Practice in both power-on and power-off stalls is important because it simulates stall conditions that could occur during normal flight maneuvers. It is important for pilots to understand the possible flight scenarios in which a stall could occur. Stall accidents usually result from an inadvertent stall at a low altitude, with the recovery not completed prior to ground contact. Fo.. 2021. 12. 26. AFH Chapter 4-14 Fundamentals of Stall Recovery - 2 4. Add thrust/power. Power should be added as needed, as stalls can occur at high power or low power settings, or at high airspeeds or low airspeeds. Advance the throttle promptly, but smoothly, as needed while using rudder and elevator controls to stop any yawing motion and prevent any undesirable pitching motion. Adding power typically reduces the loss of altitude during a stall recovery, but .. 2021. 12. 25. AFH Chapter 4-13 Fundamentals of Stall Recovery Fundamentals of Stall Recovery Depending on the complexity of the airplane, stall recovery could consist of as many as six steps. Even so, the pilot should remember the most important action to an impending stall or a full stall is to reduce the AOA. There have been numerous situations where pilots did not first reduce AOA, and instead prioritized power and maintaining altitude, which resulted i.. 2021. 12. 24. 이전 1 2 3 4 다음 반응형
