Hmm... Well I've certainly been present for a lot of FFOD stick pusher tests and should recognize that sound, but for some reason it sounds different in this recording.

Oh yeah. I totally forgot you have to test that thing first flight of the day on the CRJ. You'd think after pressing the damn red button for 5 years I'd remember that.

It is, for the FFOD (First Flight) tests. But I don't ever remember hearing that warbling ELT sound. That sure is strange.

That's because that's the stall warning sound, not the stick pusher. In real life any time you get the stall warning sound you'd get the pusher also, but when you test the system FFOD you are just testing the pusher, not the stall warning horn.

Hawker has a lift dump system. When lift dump is actuated the flaps goto 70 or 75 degree and the spoilers extend further.

That makes sense. Well, I definitely heard the actual stall warning horn when I did initial a couple of years ago. Not sure I did during recurrent last year. I'll have to make sure that happens this year. Hey, I'm always learning! (or re-learning, as the case may be).

Tapatalk crashed and only posted half of what I wrote.

There is some interesting stuff on there.

Also of note is Comair 3272 (EMB-120 Ice near Detroit in 1997). This one is pretty graphic.



The CVR audio surprised me. I thought that never went out even for trials.

Again, I apologize in advance if this is old news and ask the admins to remove this accordingly if so.

I was an eyewitness to that crash. I really wish I hadn't just watched/listened to that.

I'll start off by saying that this is in no way a knock against you.

That said, if you fly the actual airplane it is absolutely absurd that you can't recognize the stick pusher/stall horn sound. Part 121 training has been totally remiss in providing actual stall training to pilots. I actually only heard that sound once in a sim session prior to the change of procedure after the Colgan crash, and only because we had some extra time and the instructor said "hey, check this out". Nobody did "full stall" training because the ATP PTS didn't specify it.

I've done it in 100% of the airplanes I'm typed in, but like yours, it was "Hey, let's check this out" in one case or "Hey, can we take this box up to 370 and recover at the pusher?"

Isnt checking the stick pusher on the CRJ check list?

As like a preflight check? I doubt it. Our pusher in the dash uses nitrogen from a bottle in the nose to make it 'push', so if you tested it continuously, MX would have to replenish the bottle every week or so.

That, and in the Dash there's no way to test it and make it push. We do can test the shakers, which checks the stall warning systems.

I don't know about the RJ.

It is on the CRJ, FFOD check.

Totally missed the last 20 posts on you guys talking about the pusher test on the FFOD. Carry on.

I never knew it was pneumatic on the Dash. The CRJ has an electric motor mounted on the FO's yoke that pushes. Since the yokes are linked (normally) it pushes both forward.

I just did some reading up on that Bro accident. Apparently they weren't flying a minimum icing speed? Was it in VMC/IMC conditions? It's kind of hard to tell what exactly happened.
 
Wooooah, I never knew that CVR was released. I thought I've listened to them all until now, well at least the ones that were released. Thanks for posting.
 
I knew the FO of Comair 3272. Was a noob in flight school and he showed us some videos of spins in a C-152 he had taken. He was finishing his initial CFI. That is some sad irony right there.

Just be glad you don't fly the ERJ. Every......single.......flight......

I swear to god, that plane will make you go deaf before you're 30, which is amazing since it's a jet in which you can barely even hear the engines.
