- Chapter 5: Maintaining Aircraft Control: Upset Prevention and Recovery Training › Stalls › 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 action. Pilot training should emphasize teaching the same recovery technique for impending…
- Chapter 5: Maintaining Aircraft Control: Upset Prevention and Recovery Training › Stalls › 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 ... clear an obstacle. Airplanes equipped with flaps or retractable landing gear should normally be in the takeoff configuration; however, power-on stalls should also be practiced with the airplane in a clean configuration (flaps and gear retracted) to ensure practice…
- Chapter 13: Transition to Multiengine Airplanes › Spin Awareness and Stalls › Power-On Approach to Stall (Takeoff and Departure)
Power-On Approach to Stall (Takeoff and Departure) A power-on approach to stall is trained and checked to simulate problematic takeoff scenarios. A power-on approach to stall may be performed from straight-and-level flight or from shallow ... medium banked turns (up to 20 degrees of bank). To initiate a power-on approach to stall maneuver, the area surrounding the airplane should always be cleared to look for potential traffic. The airplane is slowed to the manufacturer…
- Chapter 5: Maintaining Aircraft Control: Upset Prevention and Recovery Training › Stalls › 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 ... ensure familiarity with handling arising from mechanical failures, icing, or other abnormal situations. Airspeed in excess of the normal approach speed should not be carried into a stall entry since it could result in an abnormally nose-high attitude…
- Chapter 9: Aircraft Electrical System › Introduction › Power Factor
Power Factor As seen in Figure 9-30, the resistive power and the reactive power effect the circuit at right angles to each other. The power factor in an AC circuit is created by this right angle effect. Power factor ... defined as the mathematical difference between true power and apparent power. Power factor (PF) is a ratio and always a measurement between 0 and 100. The power factor is directly related to the phase shift of a circuit. The greater…
- Chapter 12: Fundamentals of Electricity & Electronics › Apparent Power Defined
True Power Defined True power of any AC circuit is commonly referred to as the working power of the circuit. True power is the power consumed by the resistance portion of the circuit and is measured in watts. True power ... symbolized by the letter P and is indicated by any wattmeter in the circuit. True power is calculated by the formula: Apparent Power Defined Apparent power in an AC circuit is sometimes referred to as the reactive power…
