What Is Dutch Roll In Aviation - [Understand What Causes This Aerodynamic phenomenon]. 

===========================================================================
In today's video, I'm going to talk about the Dutch Roll.
The Dutch Roll is a combination of rolls and yaws that occur at the same time, you have to imagine your airplane oscillating around your longitudinal and lateral axis.
In order to understand in full the Dutch Roll, we need to talk about Aircraft Stability.
The stability of your aircraft is the ability to come back to the previous state once disturbed by any outside factor or a Pilot Input.
An aircraft that has Lateral stability is able to come back to wing level after a right or left turn.
Directional Stability is the ability of your aircraft to come back to its previous state after a Yaw is induced.
The Dutch Roll affects mostly the Aircraft equipped with swept wings.
The Aircrafts affected by this aerodynamic phenomena have, normally, a system that corrects the Dutch Roll, this system is called Yaw Damper.
The Yaw Damper sends rudder inputs very quickly under certain situations when it detects the presence of Dutch Roll.
If your aircraft is stable it will correct slowly the Dutch Roll even without the Yaw Damper.
