반응형 원해남5 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. PHAK Chapter 6-20 Balance Tabs Balance Tabs The control forces may be excessively high in some aircraft, and, in order to decrease them, the manufacturer may use balance tabs. They look like trim tabs and are hinged in approximately the same places as trim tabs. The essential difference between the two is that the balancing tab is coupled to the control surface rod so that when the primary control surface is moved in any dire.. 2021. 8. 20. PHAK Chapter 6-18 Spoilers Spoilers Found on some fixed-wing aircraft, high drag devices called spoilers are deployed from the wings to spoil the smooth airflow, reducing lift and increasing drag. On gliders, spoilers are most often used to control rate of descent for accurate landings. On other aircraft, spoilers are often used for roll control, an advantage of which is the elimination of adverse yaw. To turn right, for .. 2021. 8. 18. PHAK Chapter 6-7 Coupled Ailerons and Rudder Coupled Ailerons and Rudder Coupled ailerons and rudder are linked controls. This is accomplished with rudder-aileron interconnect springs, which help correct for aileron drag by automatically deflecting the rudder at the same time the ailerons are deflected. For example, when the control wheel, or control stick, is moved to produce a left roll, the interconnect cable and spring pulls forward on.. 2021. 8. 7. PHAK Chapter 6-6 Differential Ailerons Differential Ailerons With differential ailerons, one aileron is raised a greater distance than the other aileron and is lowered for a given movement of the control wheel or control stick. This produces an increase in drag on the descending wing. The greater drag results from deflecting the up aileron on the descending wing to a greater angle than the down aileron on the rising wing. While adver.. 2021. 8. 6. 이전 1 다음 반응형
