So literally hanging around the departure gates hoping there'd be a no-show and hopping on where-ever it was going. Many years ago, I heard about something similar to the "freedom of Canada" ticket. A major airline offered a deal where if you bought a special ticket, you could fly anywhere you want. You had the ability to take as many flights as you wanted to. That one ticket covered the cost of it all. There was a catch, though. You had to travel eastward. This allowed you to travel around the globe for one set price. It was affordable, too. I wonder if any airlines still offer that.

When I was training to be a pilot, I realized how important it was to study these same things. I figured if you have a comprehensive understanding of what causes a plane to crash, then it helps you to avoid being in one. You know what to look for. In most cases, the chain of events that lead up to a crash are innocuous little things that go unnoticed until it's too late. Little distractions that you'd never think could pose a danger have the potential to lead to huge disasters. The training was more about safety than anything else, and that's how it should be.

I don't remember how much fuel you burn just taxiing to the runway, but it's actually a lot. I'm not fan of the pollution either, but without fuel, you're not going anywhere.DerekT-P wrote: the vapour trails, which as far as I'm concerned are a horrific graffiti in the sky.

From what I understand, I don't believe contrails themselves contribute to global warming. Contrails are just like any other high-altitude cirrus clouds. They consist of ice crystals. Those ice crystals reflect sunlight back into space. If sunlight is reflected back into space, it's not reaching Earth. If less sunlight reaches the surface of the Earth, then less heat will reach the surface of the Earth as well.
Anyway, climate change is a volatile and highly charged subject, so I'll leave that alone. I enjoyed reading your post. I envy you for having traveled to so many places. Not many people ever get that sort of opportunity.

I caught the flying bug when I was stationed in Germany and got my private pilot's license there and then went together with my dad (a flight instructor) to purchase a used airplane. Now I am trying to build a low-cost avionics network supporting navigation (both GNSS and ground-based), ADS-B and airframe and engine sensors.

At least not without knowing he has engine trouble ...

Quote: The so-called Dutch roll, said to have been named after an ice-skating technique attributed to the Netherlands according to a BBC article.

Interesting.
Because I was under the impression that ice skating is prevalent in Alpine countries. And Netherlands is not one of them.

I even see some of the figures playing a game of curling

A TV report said that a Dutch Roll is a side to side motion caused by application of the pedals that cause the nose of the plane to move in a figure 8 pattern horizontally. They said the passengers might not notice this type of motion but it would freak out the pilots if they were not actively controlling the pedals.

So what is Dutch about that? (I guess that is what the OP really was curious about.)

Shruggs: and Google says:
What is a "Dutch roll"? "Dutch roll" is a name given to the combination of a yawing motion when the tail slides and the plane rocks from wingtip to wingtip. It is said to mimic the movement of a Dutch ice skater.

I take issue with the word "roll". I think it should be called the Dutch Yaw, because from what the (terribly uninformative) youtube / newscast(er) described, I believe it was a yaw and in no way a roll.
If I hear a jet-liner rolled I'm thinking serious stuff. But this was a yaw, like turning to the right and back to the left.
You think maybe they were trying to sensationalize the story a bit?
No, no, not the news.

The way I heard the explanation of the Dutch Roll is that it also involves the ailerons, so yes, there is a roll component to the motion.
The difficult we do right away...
...the impossible takes slightly longer.

A Dutch Roll is actually a roll that occurs as a result of a yaw. If you're flying an airplane that has swept wings, and yaw is induced, then it can happen. I've never heard of it being a danger to the flight of an airliner.
When a yaw does occur, it causes the plane to roll as though you were controlling the ailerons. A yaw can change the rate of airflow over each wing differently. Hence, the wing that encounters an increased airflow generates more lift. The wing with a lower airflow produces less lift. Thus, a roll occurs.
And yes, the news of this event is WAY overhyped.

The are some phrases in English that use "Dutch" in a derogatory manner, e.g. "Double Dutch" meaning "nonsense". I expect that "Dutch Roll" is more of the same - using a yaw to initiate a roll being just the bass-ackward kind of thing that a Dutchman would do.
Freedom is the freedom to say that two plus two make four. If that is granted, all else follows.
