In the event of an inadvertent departure from controlled flight, what should be the initial PCL setting?

In the scenario of an inadvertent departure from controlled flight, the appropriate initial power control lever (PCL) setting is to move it to the IDLE position. This action is vital because reducing thrust quickly helps facilitate recovery efforts. When the aircraft is in a state of uncontrolled flight, such as a stall or spin, excess thrust can exacerbate the situation by increasing aerodynamic drag and complicating recovery maneuvers.

By setting the PCL to IDLE, the pilot reduces the engine power, allowing for a more manageable flight condition that aids in regaining control. This setting is critical in stabilizing the aircraft and ensuring that the ailerons, elevators, and rudder can effectively be used for recovery as the pilot works to restore controlled flight.

In contrast, other settings such as OFF would completely shut down the engine, which is unnecessary and counterproductive during recovery. MAX power could increase the aircraft's angle of attack and further destabilize its flight. MID RANGE may not provide the required decrease in thrust necessary to facilitate effective recovery. Therefore, IDLE is the correct setting to ensure safety and regain control of the aircraft efficiently.
