  Chapter 9: Approaches and Landings › Emergency Approaches and Landings (Simulated)

  Emergency Approaches and Landings (Simulated) During dual training flights, the instructor should give simulated emergency landings by retarding the throttle and calling “simulated emergency landing.” The objective of these simulated emergency landings is to develop a pilot’s accuracy, judgment ... planning, procedures, and confidence when little or no power is available. A simulated emergency landing may be given with the airplane in any configuration. If the simulated power failure occurs while above best glide speed, the pilot allows the airplane…

  have set zero thrust and the right engine is simulated feathered." Any ambiguity as to who is operating what systems or controls increases the likelihood of an unintended outcome. Following a simulated engine failure, the instructor cares for the "failed ... engine just as the learner cares for the operative engine. If zero thrust is set to simulate a feathered propeller, the cowl flap is normally closed and the mixture leaned. An occasional clearing of the engine is also desirable…

  Chapter 13: Transition to Multiengine Airplanes › Operation of Systems › Feathering Propellers

  Both feathering and starting a feathered reciprocating engine on the ground are strongly discouraged by manufacturers due to the excessive stress and vibrations generated. As just described, a loss of oil pressure from the propeller governor allows the counterweights, spring ... and/or dome charge to drive the blades to feather. Logically then, the propeller blades should feather every time an engine is shut down as oil pressure falls to zero. However, below approximately 800 rpm, a reduction in centrifugal force allows…

  constant engine speed (rpm). Most of the steel hub Hartzell propellers and many of the aluminum hub are full feathering. These feathering propellers operate similarly to the nonfeathering ones except the feathering spring assists the flyweights to increase the pitch ... engine is shut down to prevent exposure and corrosion of the pitch changing mechanism. Figure 7-25. Constant-speed feathering propeller. Feathering is accomplished by releasing the governor oil pressure, allowing the flyweights and feathering spring to feather the blades…
