Malaysia Airlines 777 missing

[fholbert]

I understand what you are saying....but you still don't get it.

I pretty much have you figured out.

 

[fholbert]

?

Oh god, now he's going to say a 777 has 5 transponders.

 

[brent p h]

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 con
trol unit on the panel so you can set a new beacon code, but there is no transmitting going on.

So let me get this straight....on the 777 and all Boeing aircraft there is no triple redundancy?

So this sums up your feeble attempt at mockery?

Why waste money on three transponders?

What does that have to so with anything? Hell, the podunk CRJ I fly has 3 hydraulic systems. Guess what, they don't do anything with the engines shut down and the pumps in the off position. Or are they like our two transponders? Can't turn them off either?

CNN yesterday repeatedly broadcast different live segments from inside a 777 simulator with pilot. He showed where the transponder was located on the center pedestal, and how it could be turned off with a switch on the unit.

Did I dream that?

You watch too much TV. Count the yokes in the picture below. Now count the throttles.

Two engines, two pilots does not equal triple redundancy.

Like candy from a baby...

The one I saw on CNN, very large pilot, had just a standby position. But standby is pretty much off off.

No mockery, I was being truthful.

Are we talking about transponders or ACARS? Or the separate engine trend monitoring transmitters? The transponders, it appears, seem easy to turn to stby.

@typhoonpilot, can you help us put this 777 transponder issue to rest?

Please don't, I'm really enjoying it. Like driving past a car accident, can't help but look.

Interesting how when 777s, or any plane, land at SFO, the ground radar I have up here in the ramp tower shows the planes ID/squak until about the time the plane exits the runway, then it magically disappears becoming an anonymous blob the rest of the way to the gate. It's almost like the pilots run a checklist and put it in standby mode or something.

Newer Garmin installations do the same thing. Once below 30kts, transponder goes to ground mode. G1000/3000/5000 etc.

Yeah... let me at least post my favorite situationally appropriate video first.

 

[Vector4Food]

Why. Both US and Canada had passengers on the flight.

Boeing

 

[fholbert]

Boeing

You're thinking none of the parts are made in Canada?

Fair point

Fact is the US has the assets and presence to assist in that area. Canada does not.
