What is a "Dutch Roll"?!

Published 2019-12-13
So, How "Dutch" is a " Dutch roll" and can it be dangerous. What roll does the "Yaw damper" have to do with all of this?
In todays video I will be talking about a fascinating aerodynamic occurance called the "Dutch Roll". I will explain how it is connected to the stability of the aircraft as well as the different axis of movements that are involved in it.

Whoâs also here after the Boeing 737 Max news???
-
Your dog should be a pretty good pilot by now.

Who came here as a result of reading about SWA 746 on a 737 Max 8 enroute from PHX to OAK on May 25, 2024? The FAA is now officially conducting an in depth investigation into why it went into a "Dutch roll".

Cute little dog was showing us the YAWN axis where she ended up remarkably stable on his port side.

Time to revisit this video

Revisiting this video after the Southwest incident in Hawaii!

Back when the 737-100 was new my dad was the manager for the Conductron 737 flight simulator program. Dad brought the family in to see it on a weekend and I got to sit in the right seat and "fly" the SN 2 simulator with Boeing test pilot Kit Carson in the left seat. He was checking out the simulator before accepting it for delivery. The first thing I did was put the simulator in a Dutch Roll. Kit Carson was the man who introcuded me to that term. The Conductron 737 flight simulator was the first all digital flight simulator where the flight dynamics were calculated using numerical methods in the digital computer instead of using analog computers to do those calculations.

I find myself staring at your dogs during these videos! As an aviation enthusiast and frequent traveler love this channel. Thank you!
-
Thank you for flying with KLM. For some appetisers, we'll be served Dutch Rolls

This guy made me an aviation enthusiastâ¤

There's a pilot technique I learned during my B737 flight test work that will manually dampen out the dutch roll. With the yaw damper inop, momentarily just turn the yoke into the rising wing (for just a quarter of a second, that is), and return back to neutral. This raises the flight spoilers on the rising wing, dampening out the yaw effect. Repeat as necessary ...

It was very good of the dog to let Mentour appear on its show
-
I love that doggo does not care at all.

This is why I love this channel. A quick ad at the beginning, a quick ad at the end, and in the middle is a nice calm and informative explanation. Just like a coordinated turn, I watch a coordinated video. Putting in just enough technical meat to keep me flying smoothly til I land safely and a little more educated at the end. I despise videos where I'm being constantly spammed with adverts just when I'm starting to get into the zone, even interrupting mid-syllable. Thank you for not being that person!

I was in the very back row of a WestJet 737 landing in a very windy Montreal and the plane did exactly that. Rocking side to side and twisting left to right while the nose pitched upâŚand then downâŚand then up again. Of course I thought we were going to either flip over or go right off the runway. đ Holy crap. I didnât know it had a name!
-
I enjoy watching your videos about the way planes work and how to fly them even though I'll probably never be a pilot, because they put my mind at rest for being a passenger in a plane.

So we study this phenomenon in aerospace engineering. Our professor told us that the name came from the fact that the Dutch were, back in the day, sailors who spent very long times at sea, inherently getting used to the movement of the boat caused by the waves. Once they got to port and stepped on steady ground, they were known for struggling with the balance and walking in this characteristic manner weiving from left to right. Since the movement of an aircraft was somewhat similar, the name was attributed to this stability mode. This explanation is rather anecdotal and I have no idea if it is even true. Anyway I just wanted to share this with all of you. As usual, awesome video and awesome explanations. Keep it up!

The dog obviously has heard it all before and doesnt need to know more. Such a cool pup.
-
As a technical Aircraft engineer and aerodynamic instructor , this explanation is 100times better than many I have seen and read. I always like to give practical examples to students to understand such phenomenons . In the technical world , we always perform checks on damper system for force feedback etc.

A Dutch roll is malicious; a Swiss roll is delicious. ;-)
