Oh! China!

It was the time last summer, when I went to China with my gf and her parent. From JFK to HKG on 5/29/2005 on an Airbus A340-600 jet (CX831). The flight was a polar route. Unfortunately I didn't see any polar bear... :lol:

The flight was pretty much smooth from JFK all the way to entering Siberia. The pilot kept increasing altitude, from 33000ft in Canada to 41500ft when entering Siberia. The scene was very nice and I had a few pictures from rivers over Canada to polar ice caps in Arctic Ocean to mountainous region over central Siberia. But when after we left Mongolia, just entering Chinese province of Inner Mongolia, we experienced some moderate turbulence all the way down to Hunan province (3 hour duration, sigh). All I knew was that some were clear air and some were over high clouds. At 41500ft the clouds were like almost touching the a/c, and sometimes the a/c just went into clouds. The a/c sometimes rose and dropped when we were over clouds. Breakfast was delayed for 1 1/2 hours. Interesting thing was, in common sense an aircraft should fly straight, but the flight path was in curves. I have no idea why, but it was making some turns to the southwest then to southeast and back to the southwest again. Funny on that, but not really comfortable.

P.S. on the trip back to JFK, the path was much smoother, but it still had a lot of clear air turbulence just past Beijing. I would say, going over the Pacific would be much better, I guess. Path over Arctic Ocean was extremely smooth, nothing really happened. And I could, for the first time, see the Sun rising from the west... :lol:

Re: Oh! China!

If you use the Great Circle Mapper, it will show the shortest path between two airports. On a sphere (like Earth), the shortest line between two points is a curve.

Also, the polar routes are of great interest to site vistors, because these are almost always smooth because there isn't really anything to cause turbulence near the poles.
