What is the most effective way to recover from a Dutch roll according to aviation standards?

The most effective way to recover from a Dutch roll is to use coordinated rudder control. A Dutch roll is a coupled motion of yaw and roll that occurs due to the aircraft's lateral instability. When the aircraft begins to yaw to one side, it also rolls in that direction, and if left uncorrected, this motion can oscillate.

Coordinated rudder control addresses this issue directly by counteracting the yaw motion. The pilot applies rudder input to regain straight flight, which helps quell the oscillation. Proper use of the rudder aligns the aircraft's nose with the direction it is flying, restoring stability and preventing the oscillatory motion from escalating.

Utilizing aileron control alone can increase the rolling moment but doesn't effectively manage the yaw component, which is crucial in a Dutch roll scenario. Increasing engine thrust or lowering altitude quickly would not directly address the underlying dynamics of the Dutch roll and could even exacerbate the situation without proper rudder input. Thus, coordinated rudder control is the key to stabilizing the aircraft and successfully recovering from a Dutch roll.
