Air India plane crash

I've done the ops test on Bombardier Global RATs in the hangar, it requires special equipment, it's loud and sounds like a really big R/C airplane. I've never heard one deployed while an airplane is airborne.

How do you get it to turn in a hangar? As I recall the 757 RAT needed 130 knots for it make minimum hydraulic pressure.

Oh, I know who you’re talking about now. Interesting, didn’t know he had done a piece on this, as I’ve only seen his video adverts that have the various subject matter for that video listed out.

There's a whole contraption with a big cage and a big electric motor to turn the prop that you mount after you manually deploy the RAT. When you read the AMM regarding anything to do with the RAT you'd think the blades were fashioned from the dust under the nest of the goose that layed the golden egg, what I'm trying to say is they're expensive and fragile and precautions have to be taken to ensure they're not inadvertently damaged. There is an alternate procedure to do the test inflight, but because sometimes you've got half of the airplane disassembled and the clock keep sticking towards your deadline you do things in the hangar, I've been involved in restowing the contraption once the airplane lands but I've never heard it in the air.

All the data recorders have been found. We will all know soon enough…

The other night I went to a baseball game with my friend that’s a 787CA. In their words, Boeing already knows what took place without a FDR as the aircraft reports in real time to their airline’s maintenance department as well as the manufacturer. Apparently a much more advanced system than what MH370 had.

No, a guy named CW Lemoine who has a YouTube channel. Video suggestions always come up that I see, but I haven’t ever sat and watched one of his videos.

Ha!, I just got who you were referring to, our favorite Canadian ATC guy! Good dude.

The 787 is nice how chatty and prolific it is for knowing a lot of things.

But from a practical perspective it probably didn’t tell much in the 30 seconds while it was airborne, and especially if it was experiencing power interruptions/system resets (unknown at this time).

True. Flight time was very brief, not sure how often it “reports”.

The RAT speculation comes from the one video that is cropped and compressed to hell. At this point I believe it is a video artifact rather than the RAT.

Tho cropped, its visible from more than one angle. Quality is poor, yes. However, its gotta be either the RAT or a single gear door...but something is hanging down other than the gear...in the RAT area.

The test is usually done after the engineers and mechanics eat a big Mexican lunch. Wind for days to test that thing out

Hey! I resemble that remark. Truth be told most times I eat a light lunch because I don't like feeling sluggish in the afternoon. But there are times when a big lunch is appropriate and we try to do that sort of thing when things aren't busy. I've already introduced some here to the Greek goodness of Firehouse but I may have neglected Springbok. It's mostly a bar. Both are solid lunch or dinner spots if you find yourself at KVNY.
 
If you want to understand technical details, just Google it.
