UA839 LAX-SYD Via Atlantic & Indian Ocean NOW!?!?

Tue Jun 27, 2006 11:06 pm

http://flightaware.com/live/flight/UAL839

Still inflight...hope this link works...take a look.

I've been tracking UA fl.839 (Departure on Monday June 26th & still inflight)...one of my coworkers is on it...it took a sharp "left" after a short segment out to sea after leaving L.A. I've never seen this, nor did I know airlines did this routing. How often does this occur?

This routing blew me out of the water...I never thought you could possibly cross Mexico, the Caribbean, the Atlantic and Indian Ocean, and Africa to get to Sydney from LA!?!?!? You learn something new everyday.

Dont trust flight trackers over the oceans.

Flight trackers rely on radar data from the US/Canada for their updates. After it leaves radar coverage the flight tracking is no longer reliable.

I am most positive there is an error in the flightware tracking software. There is absolutely no way UA would fly LAX-SYD across any ocean other than the Pacific.

It would take the best part of 30 hours to fly that way... ie over the Atlantic, Africa and Indian Oceans, and Australia itself! Its about 14,000nm as opposed to the direct LAX-SYD Pacific Ocean route which is 6500nm and takes about 13 hours.

Nothing like showing the novice side of my aviation knowledge! I thought that might take mighty strong tailwind...and then some. You know in those Looney Toons cartoons when one of the characters turns into a sucker-pop or an jackass ...yep...that's me right about now.

you can see the line of flight makes an abrupt change right about the point radar coverage would be terminated off the coast of CA. If you notice at the bottom of the graphic, there's a disclaimer that reads:

Wow!! Supersonic UA!! This flight covered around 14,000 miles in just 8hr 28 min!!! That's an AVERAGE speed 0f 1650mph - faster than Concorde and a new world record!!! Thought we had seen the last supersonic passenger flight in my lifetime several years ago. But way to go!!!

Of course they must have gone the wrong way (east instead of west) because of the jet stream or something. I mean if they had flown the right way across the pacific and taken the same length of time they would only have AVERAGED about 765 mph. And that's scarcely above Mach 1 - almost tortoise pace!!

Yeah, you can' trust flight trackers outside of US/Canadian Airspace. You can see that the flight time has been incredibly wrong on the previous LAX-SYD flights.

I looked up DFW-NRT before I went and it was showing a flight time of around 7hrs, 30min, which we know is totally false, especially westbound.

This little snippet of info also gives the game away :-

FICKY 2500N 13000W 2100N 13500W BELAN
1500N 14300W 0900N 15000W 0500N 15600W
0100S 16500W 0400S 17000W 0500S 17227W
0800S 18000E GITON 1400S 17000E 1800S
16500E 2003S 16300E 2300S 16000E IFFEY

The flight is going WEST as can be seen from the routing.

On routes that are mostly east-west then yes the winds can really effect them. However LAX-SYD is mostly a north-south route. There are not huge dominant winds going north and south. The jetstream goes around the globe roughly parallel to the equater with some dips and dives. The winds don't really move north-south except in small areas.
If you have never designed an airplane part before, let the real designers do the work!

many of the flights to Asia end up looking like this on Flight Aware as well, or they just "disappear"

I have also seen trackers with valid radar ping info from the UK, Guam, New Zealand and some Caribbean countries to name a few. I guess they have bilateral radar agreements...  Smile

Looks to me like the whole lot of info on that tracker is bull$h1t - take a look at the track log and see how the flight rollercoastered between 29,000 and 1,000 feet over the ocean - if that is to be believed, those passengers must've feared their lives.

Looks like flightaware.com is not worth much IMHO  thumbsdown

I don't see why they can't track farther over the pacific if they can track the Hawaii flights without a problem.

He he, funny indeed. Would love to be on a 744 that dives down to a 1000 feet every once in a while.

Yea, I don't think it's reliable, AT ALL! I just did a test with UAL flight#914 from IAD-CDG and it says it takes 14hrs 4 mins. So on one hand, we have UAL, the supersonic airliners, and on the other hand, we have UAL, the turtle of airliners. Doesn't seem to add up quite right. Heck, at least it didn't go west through the Pacific/Indian oceans to Paris.

My flight LAX-SYD (not on UA, on NZ) took 14h. This one is taking 14h 30minutes, and going the same way. And you can clearly see that in the beginning from LAX the jumbo is going straight out to the ocean, and then suddenly turns 90 degrees left. Must be a bug or something..
