Malaysia Airlines 777 missing

No

Not a 777 expert but am an ATC expert.

1.) Imagine the ring around when ATC RADAR is located on an airport if the pilot couldn't stop the transponder from responding.

2.) In flight a 777 would appear to be a flight of two, or near miss, if both transponders were responding.

The inconsistencies dont add up
If they were in this situation, the pilots would not switch off the radar trackers of the plane, let alone be thinking of doing so. If anything they would make sure the trackers were on.

Ok, now I'm confused. Unless I'm misunderstanding you, you're arguing against what I said, which is the theory you posted?
 
The theories folks are coming up with are entertaining. The plane was hijacked, and now it's sitting deep in the Indian Ocean. We'll find out by whom and maybe why if they ever locate the wreckage, CVR and black boxes. Took a while to find Air France in 13,000ft deep
 
Curious. Given the circumstances of this week, does anyone see a downside to preventing transponders from being disabled on commercial aircraft?

We also had a relative idea of where that one was. The search area on this one is now what, about 1/8th of the earth's surface?

A shorted wire can cause a fire. Every electronic needs a circuit breaker in an aircraft. I guess you can make the circuit breaker inaccessible from the cockpit. But then if it pops the crew wouldn't be able to recycle it...?

Yep. With such a huge search area, and so much of it being water, I'm not at all surprised we haven't found it yet. Its a big airplane, but when you think about it in square miles, its a needle in a haystack. I'll be shocked if its never found, but I doubt it'll be anytime soon if it hasn't been found already.

Yes, see below.

I know you did.

Will it? If you turn something off (select stand-by mode as it appears there is no "off position" though they are effectively the same) or remove electrical power from the component by pulling the circuit breaker, it will not transmit. Is my understanding of basic aircraft systems incorrect?

Everyone thinks it's USA's job to save the world. Why?

If Canada is 1/10 the size let them chip in 1/10 the effort.

Who said they're not? Not that Im saying they are, but I have no evidence to the contrary.

And again, the US has a vested interest in finding this airplane.

Your not paying attention..... I stated on the 777 they're not able to be turned off.

Brent you're wrong. There is a "standby" switch position on the transponder, just like almost all other Boeing aircraft. When the switch is in standby nothing gets transmitted. Power is still being applied to the actual transponder and the control unit on the panel so you can set a new beacon code, but there is no transmitting going on.
