- Chapter 5: Maintaining Aircraft Control: Upset Prevention and Recovery Training › Slow Flight
pilot training and testing purposes, slow flight includes two main elements: ⦁ Slowing to, maneuvering at, and recovering from an airspeed at which the airplane is still capable of maintaining controlled flight without activating the stall warning ... knots above the 1G stall speed is a good target. ⦁ Performing slow flight in configurations appropriate to takeoffs, climbs, descents, approaches to landing, and go-arounds. Slow flight should be introduced with the target airspeed sufficiently above the stall…
- Chapter 11: Aircraft Performance › Climb Performance Factors › Region of Reversed Command
majority of aircraft flying (climb, cruise, and maneuvers) is conducted in the region of normal command. Flight in the region of reversed command means flight in which a higher airspeed requires a lower power setting and a lower airspeed requires a higher power setting to hold altitude. It does not imply that a decrease in power produces lower airspeed. The region of reversed command is encountered in the low speed phases of flight. Flight speeds below…
- Chapter 9: Approaches and Landings › Power-Off Accuracy Approaches
accomplish this, it is essential that both the descent angle and the airspeed be accurately controlled. Unlike a normal approach when the power setting is variable, on a power-off approach the power is fixed at the idle setting ... Pitch attitude is adjusted to control the airspeed. This also changes the glide or descent angle. If an airplane is on approach with an airspeed higher than best glide, pitching down will increase the airspeed and steepen…

airplane. In propeller-driven airplanes, torque, slipstream effect, and P-factor may produce a strong left yaw, which requires right rudder input to maintain coordinated flight. The closer the airplane is to the 1G stall, the greater the amount ... right rudder pressure required. Figure 5-7. Slow flight—low airspeed, high angle of attack, high power, and constant altitude. Maneuvering in Slow Flight When the desired pitch attitude and airspeed have been established in straight-and-level…
- Chapter 5: Maintaining Aircraft Control: Upset Prevention and Recovery Training › Slow Flight › Performing the Slow Flight Maneuver
cases, practicing slow flight should be conducted at an adequate height above the ground for recovery should the airplane inadvertently stall. To begin the slow flight maneuver, the pilot should clear the area and gradually reduce thrust from cruise power ... airplane decreases, there is a change in the sound of the airflow. As the speed approaches the target slow flight speed, which is an airspeed just above the stall warning in the desired configuration (i.e., approximately 5–10 knots…
- Chapter 7, Section I: Airplane Basic Flight Maneuvers › Straight-and-Level Flight › Turn-and-Slip Indicator (Needle and Ball)
Figures 7-18 and 7-19 provide a comparison of the two instruments. Power Control Power produces thrust which, with the appropriate angle of attack of the wing, overcomes the forces of gravity, drag, and inertia to determine airplane performance ... Power control must be related to its effect on altitude and airspeed, since any change in power setting results in a change in the airspeed or the altitude of the airplane. At any given airspeed, the power…
