Inappropriate comments about RJ crash?

[belchfire]

As an ignorant autopilotless turboprop pilot
I can figure out that not accelerating could
very well be because of the ball being out
of wack.

WHY was the ball so far out? WTF was
that about? Was that the first indication
of one of the engines getting sick? Was
the yaw damper screwed up? How
much athority does the ap have on the
rudder? Did the first engine flame out
because of the unstable airflow of being
out of yaw trim? Did one of them have
a boot on a rudder?

I also have no experience with FADEC but
if I am not mistaken the crj has it. Why
was it not protecting the one engine that
overtemped?

If it was because of an engine getting
weak, flaming out or whatever (were some of
the "bangs" or "thumps" compressor stalls?)
why weren't there trim beeps from
the ap as thrust decreased and why wasn't the
ap doing something?

I read the "sound simular to ap disconect"
so it was on at some point...

Is it possible that an excessive reliance on
automation to keep them out of trouble led
to the widely expressed absence of so called
"professionalism" in this case?

The jetpigs emergency proceedures allow for
airstarts outside the demonstrated parameters
in the event of a double engine failure. Is this
the case for the crj also?
As far as the word dude goes I think we have
a first usage as the final word on the cvr. Usually
it is something that has an "s" and a "t" in it
if the crew knows they are about to hit.
I have been told of a guy that always says
"What was that?" after setting the power...just in
case...

God help me but there is a phrase that I want
to use if I know that someone is going to
be pulling the tape...it ain't dude and it lacks
the usuall "s" and "t" but I could
probably work them in just to make people
scratch their heads even more...probably be too
busy to think about it though...

There are the final words from one transcript
that are burned into my memory...
"I just remembered. The highest point around here
is forty-four hun..." (sound of impact)

Dust off your memory items and fly safe!

How about, "Oh my, my look at the tentacles on that thing"?

Belchfire, no FADEC's on the CRJ (the "stretch" has them however). The autopilot also disconnects and if memory serves me correct won't engage when the ADG / EMER POWER is alive and kicking.

We don't have any information that the aircraft was that far out of trim. We don't have a "ball", we have a "brick", and we don't know if that's what he was referring to or not. There is no indication the Y.D. was malfunctioning. The autopilot doesn't have ANY authority over the rudder - it's not an autopilot-controlled flight surface.

Did the first engine flame out
because of the unstable airflow of being
out of yaw trim? Did one of them have
a boot on a rudder?

Data indicates both engines failed nearly simultaneously.

If it was because of an engine getting
weak, flaming out or whatever (were some of
the "bangs" or "thumps" compressor stalls?)
why weren't there trim beeps from
the ap as thrust decreased and why wasn't the
ap doing something?

Because unless the autopilot trims up CONTINUOUSLY for several seconds, there is NO aural indication that the autopilot is trimming the stab. The autopilot WAS doing something - it was holding altitude as it had been commanded until the first shaker, at which point it automatically disconnects.

Is it possible that an excessive reliance on
automation to keep them out of trouble led
to the widely expressed absence of so called
"professionalism" in this case?

No. Absence of professionalism started at the first decision to "goof around" with an aircraft they didn't own (or understand), continued with the decision to swap seats, and culminated with the decision to take the aircraft an altitude it shouldn't have been at for its weight and temperature at a speed that was unable to sustain that flight.

The unfortunate thing is that this should have ended up with a trip to the Chief Pilot's office, followed shortly by a trip to the unemployment line, not a trip for the families to a burial site. Why the engines didn't relight is the primary concern of the moment. Secondary to that is the training of all our pilots not already well-versed in high altitude swept wing jet aerodynamics that some evidently don't understand.

 

[belchfire]

How about, "Oh my, my look at the tentacles on that thing"?

That's close and pretty much my style...you could
even say "Holy (explative) dude did you see the
tentacles on that thing?" Just for TIS and TonyC...

As for the laughter after the departure from planned
operations I think that subject is covered in the
studies for the FOI written under possible reactions
to stress, fear or nervousness.

"Belchfire, no FADEC's on the CRJ (the "stretch" has them however). The autopilot also disconnects and if memory serves me correct won't engage when the ADG / EMER POWER is alive and kicking."

It is my understanding that swept wing jets are
kind of unpleasant to hand fly at 410. I know the
J-32 gets a little unhappy at 250
(if it can get there at all).

I haven't been able to download the FDR stuff for
review, but that kind of gives me the failure
timeline. It does leave unanswered the question
of why the ball got so out of whack
(Before the autopilot disconnect tone)
the pitch and yaw attitudes are the second things
that the crew notices. I don't know what kind of
warnings the machine will give you if one engine
starts spooling down but the first audio warning
of engine trouble was the "engine oil".

I don't know when the g loadings occured (except
for someone said something about a 2 g rotation,
I am guessing that was at takeoff. Betcha there
aren't many of the critics here that could start
smoothly flying a pissed off machine at 410 when
the autopilot gives up...I doubt Yeager and
Hoover waste any time here! If some of them were
after the disconnect I'm not a bit surprised.
In fact I wonder if anyone here without a glider
rating has ever trained for an unpowered stall
recovery...

Why did the yaw trim get so out of whack???
Am I the only one seeing that? Wouldn't you
hear the engine spooling down first if asemetric
thrust was the causing it? Or did the first one
flame out because of it?

The stall warning/pusher event came after
level off. Why didn't the plane accelerate?

Wonder if an engine overtemped earlier in the
climb and waited till they leveled off to give
it up...

I'm going to have to plow through all that FDR stuff...

dude, that's really lame!

 

[belchfire]

Lear, thanks for clearing up some of the
systems stuff for me. Didn't scroll far enough
back up the last time. "Brick" huh...
interesting...What were they talking
about?

Didn't see anything wierd on the FDR
stuff. Everything looked pretty much
like it quit all at once...including the
FDR for a while...pretty tough to read
on a small screen though.

Some very interesting comments here. Today was my first reading of the full CVR transcript......tough to stomach, particularly since I feed my family flying a CRJ these days.

I hope we can move on from the "dude" topic. Yeah, it's a bit disturbing to read, but I think it detracts from looking at the real cause of this accident. Safe pilots are found all over the map and from all walks of life! There are pilots I know who've never uttered the word "dude" or any other surf jargon who I wouldn't let my family ride with.

I think the most telling language used on that CVR was "four one oh, my man" and "made it, man"

This childish obsession with flying a few thousand feet higher than we normally fly the CRJ was what killed these young aviators. What would have been wrong with flying, say, FL350 that evening? To me, the earth looks about the same from FL310 on up, and who cares?!?!

As someone alluded to, the first few high altitude scares one has should leave a permanent mark on one's judgement and flying habits. It's tragic that for these guys, that first scare cost them their lives. There really is no substitute for experience, and how you gain that experience has been the subject of much debate. What's really unfortunate is that airlines don't seem to value, nor do they want to pay for, truely experienced pilots anymore. Seems to me whoever will hire on and fly cheaply is their top candidate, these days.

The CRJ is my fifth jet, and the second smallest one I've flown. I knew the first time I flew it over FL350 that there wasn't much more in it. Why anyone gets a thrill from mushing through the thin air, at M.64, with the nose pointed skyward, I'll never know. I've heard there are guys like that at my airline, though, even post-Pinnacle . And there are probably more of them out there.

Y'all take care.

I wonder how many RJ shaker and stall events (revenue flights during climb) happen each year that go unreported.. I know at my airline (soon to be previous airline) we've had at least 1 shaker and 1 pusher incident in the last 6-8 months.

The problem isn't limited to these two guys and is much more wide spread than most want to admit.

This was discussed soon after the accident, but I've forgotten the answer. Here goes again. What type of climb mode does the CRJ A/P use? Do you climb in V/S, or A/S -Mach?

If you climb in V/S,.............. why?

BeCareful, Good Post. I would like to add that while experience can't be gained outside of itself, knowledge can be gained without actually experiencing something. This topic is a great example. The knowledge of high altitude swept wing aerodynamics is readily available. A new jet pilot should be able to gain that knowledge through training and or self study. My original jet was a Lear35. I was FSI trained, but high speed stuff wasn't really emphasised, so I read up on my own. Knowing that speed is life, and that jets need to be flown by the book is such basic info that it pains me to think that someone would climb into one with out having that knowledge.

Don't know what procedures the other regionals have, but Pinnacle doesn't really require any certain mode to be used. Most of the pilots climb in VS mode above 10k because they think the speed mode isn't smooth enough. Personally, I always fly in IAS/MACH Climb mode. If you turn on Turbulence mode along with speed mode then it dampens the pitch oscillations and makes it pretty smooth.

 

[chperplt]

We (CMR) do not have any specific procedure.. We do however have minimim climb speeds. I fly in VS mode because the bird doesn't do very will in IAS mode and will make you sick....plus I don't like watching the VS drop down to 0 (I mean 50 feet) per minute over and over again.

The problem is not flying in VS mode.. Don't break open the newspaper during the climb and cover up the instruments.. The problem is that people don't understand high alt aero and or how to read climb charts.

You cannot choose for the most part your young looks, blond hair and small size. You shouldn't have to change the color of your hair, which is part of your identity.

However, you can choose how you act, dress, behave and communicate.

You can choose not to say cool words of the pop culture elite when functioning in the professional world. Words like...

Like.
Whatever.
Totally.
Awesome.

This was brought to my attention this morning. Has anyone else noted that the speedbrakes/flight spoilers were deployed at some point early in the descent and remain deployed until impact?

This is illustrated on Plot 11 of the FDR data. Initially it may seem as though only the green line (right flight spoiler) is traced but there is a small trace of red at the point of deployment and I believe that the green line simply overlays the red one.

My question is would/could they have been delpoyed while in manual reversion or is the plot showing a selected position?

I beleive I read in an earlier post that the spoilers PARTIALLY deployed because of the loss of hydraulics associated with the dual engine flameout.
