without taking into account headwind or distance traveled from KUL to 180 turn, i calculate thats a potential search area of 20 million square miles.

Nothing interesting. More propaganda than news.

Again, 777 has a stellar safety record, so I'd repeat the poster who noted that the most dangerous part of your journey will be going to/from the airport @:-)

And I'll now repeat myself, I'm not a Boeing cheerleader @:-)

Enjoy your trip

Esp the areas over land - you would think somewhere along the line, someone would take notice of a large aircraft incoming. With no apparent communications, etc. In this day & age of heightened security...

Interesting article. Turns out 75% of 777s are equipped with the Airplane Health Data system which automatically sends information to Boeing by satellite about the status of systems on the aircraft. I believe this is the system which was so helpful in the AF case. Neither Boeing or MH would comment on MH's participation in this program. Nice to know that 75% of 777s DO have access to this information, however.

I'd be more nervous about the drive over to PDX. My taxi almost ate it last month at one of the merges after Morrison Bridge-I-84 at night.

Why are there 2 circles? What do the different circles represent?

I assume you mean the airbus version

1st represents radial measure from KUL to PEK, the 2nd concentric circle represents the maximum range given the amount of fuel in the tanks.

Airplanes take on more fuel than required to fly a given route, but often not much more to avoid taking on unnecessary weight.

I'm assuming we don't know how exactly much fuel was on board the aircraft (but if someone does - please post it!), so the light circle is the distance we know it could have reached (it had to get to PEK, after all.) The shaded circle is probably a reasonable distance beyond the radius of PEK (since aircraft are loaded with extra contingency fuel in case of holds, weather, diversion, etc.)

In case anyone else was wondering, it seems Malaysia Airlines does *not* offer inflight Internet/WiFi but does offer a micro-GSM service for passenger comms (via satellite) so voice, email, SMS, and some internet browsing is possible.

I wonder if OnAir registered any data traffic through its satellites from that a/c? And, more importantly, when did it stop?

Unfortunately there are two caveats.

From upthread:

Also upthread, someone had posted that these systems don't necessarily send data continuously - some send it just 4 times (take off, cruising, preparing for landing, descending - or something.)

Ideally there's a continuous system (minute interval), or a fault triggered system, with satellite.

But Profit=Revenue-Cost.

Also this map is 'worst case scenario' and doesn't take into account fuel dumping, which if there was any kind of emergency the crew most likely did. @:-)

so, searching in the far reaches of this area would presume there was no emergency

Per Reuters, Malaysia Air did not install the Airplane Health System.

I would not be concerned about flying on that 77L. The odds of this occurring on a 777 was already low. The odds of this occurring again by the time you get on that plane would be even lower.

When AA1420 crashed in Little Rock, I was scheduled to fly on an AA MD80 from MCO to DFW that Friday. Was I concerned about that flight? No due to the odds of that happening again within a short period of time was very low. What I do recall from that flight was that the captain used the reverse thrusters to leave the gate. I had been flying that route for a month and don't recall leaving the gate without a tow on prior flights.
