United 744 hits CAT

Dubya-Dee: 🙂

Well in that case I will continue to always fasten my seatbelt on the outside of my blanket to avoid being woken up by the flight attendants and firmly secure my Gin and Tonic from tipping over.

😀

Tilted full down all the radar would paint would be the ground/water. Radar can only read a energy emitted by the excitation of particles in the air (water droplets) as they are hit by the high energy radiation of the radar dish. With nothing to excit there will nothing for the radar to read. So in clear air there is no hope that a radar can detect rapid changes in air velocity ahead. Now there are some radars that can detect turbulance in precipitation since there is something for the radar energy to hit.

Interestingly: The 747 involved in this incident was inbound to SYD from LAX just a few minutes ahead of She-Who-Must-Be-Obeyed who was inbound from SFO. The SFO flight (UA863), which must have been following an almost identical route at that late stage in the flight plan, suffered no turbulence whatsoever. You just can never tell with CAT.

Last year another UA 747 ex HNL to NRT hit turbulence without any warning and quite a number of Pax and Crew actually hit the roof, a number of them being admitted to hospital in Tokyo.

I wonder if you deflected the radar to full down setting would you be able to pick up disturbances ahead and below you and possibly take a SWAG at what might be ahead at your level? – Just a thought.

(SWAG? = Silly Wild-Arse Guess)

Can’t you see turbulences on the second screen of the cockpit?

Their are several notable problems with clear air turbulence:
It can not always be foreseen so there is no warning.
It is usually felt at its mildest in the flight deck and is generally more severe in the aft section.
It can occur when no clouds are visible.
Aircraft radars can’t detect it.
It is common at high altitudes, where cruising aircraft suddenly enter turbulent areas.
Turbulence is the leading cause of in-flight injuries. There are countless reports of occupants who were seriously injured while moving about the passenger cabin when clear air turbulence is encountered.

may be lame, but i have had a bad day!

Nice Peter! Keep ’em coming, baby! Not lame by any means.

What realy annoys me is when pax complain about it as if it was the airlines fault!

Message is clear, keep your setbelt fastened even if the light ism off, ignore at your own risk.

Thanks Ren . This problem is quite common over Pacific. That’s why passengers are requested to keep their seat belt fasten.
However we have already debated this problem before.
It always makes me nerveous to see people running in the aisles as soon as the captain has turned the signal off after take-off (and even before).

Excuse me but what does CAT stands for?

Clear Air Turbulence.
