DO328J vs BAE41

[Country Wild]

Hey ya'll I would avoid that DO328 Jet right now, June 6 2002 ACA lost all of their PFD's and MFD's going into CVG. I would hold off until it gets fixed? but who is gonna fix it?. Dornier is out of business, and Fairchild ain't backing it very well.
Go with first class date, I todays situation be thankful ya got a job. 20 years down the road will it really matter? Any way fly safe and good luck

What are PFD's and MFD's.

 

[Country Wild]

PFD are primary flight displays and MFD are multi functional displays.....they are the glass screens in the cockpit. PFD are the screens infront of each pilot and display the attitude, heading, altitude, airspeed...etc. The MFD sit between the pilots and display the engine gauges CAS messages, fuel levels, and other information depending on what screen you have selected and what information you want.

 

[popilot78]

The EICAS screen displays the engine instruments, CAS messages etc. It is located between the Cpt's and FO's PFD and MFD's The MFD displays your route, etc. They also have system pages that you can call up. For example, the electric system can be displayed along with many others on the MFD. Really neat plane to fly.

Wew. Avoided another pissing match!!!

Tailwinds...

PS J-41 rules!!!

 

[328dude]

Sounds like a dual IAC (Integrated Avionics Computer) failure. Kinda of strange if you ask me.

It's not electrical since the Capts PFD<MFD<EICAS is off the essential bus and the FO's MFD and PFD is off the non essential bus 2.

I dought they just lost their screens. Where did you hear this at?

Country Wild,

I've seen rumors go out of control, but now that I'm on the other side of the fence, I can see how they happen. Please look at our completion factors...DAL likes our airplane...a lot. If the airplane is a problem, our completion factors would reflect it.

As for J41 vs. 328, you don't have the luxury to make that choice, your fate is in the hand of the training department. I believe new hires are going into the CRJ or 328...they stopped new hires going into the 41.

I hope you get the 328 and fly on the Delta side, your opinion will change dramatically.

328dude,

I believe they lost all 5 DU's due to a failure of the 1VE panel. I'm not positive on that but it's what one of our mx guys told me.

Not to nitpick, but on the jet, DU's 4 & 5 are powered by DC Bus 2, not the non-essential bus 2. I assume it's the same on the prop.

Blue skies,

You can read th reports yourself, I used to work for a US Air xpress commuter (not flying) but in operations and have seen first had the systems and short comings of DO328 first hand. Cannon plugs? Ring any bells for you PSA folks? How about the one located in the APU intake....are we gonna take delays again this winter...anyway it is a good aircraft with some minor flaws like most A/C...some more critical than others.

 

[328dude]

Blueridge: I stand corrected. Your right about the DC bus 2. The prop is the same way. Better get back to ground school.

Where the TV's black or did they have the "big red X"?

 

[Blueridge]

>>Where the TV's black or did they have the "big red X"?<<

My understanding is that the DU's didn't all go at once. A couple of them would go black, come back, a few others would go, come back etc. I don't know if they had red X's or not. They also had smoke in the cockpit just to keep things a little more interesting. The crew did a great job getting the thing down IMO.

Well, stand corrected twice:

Doubt=Dought

Sorry 328, but pilots cannot spell or puncuate. I know, I'm one of them!!!!!!!!

Why isn't there a spell checker on this site like AOL has for emails?

Honestly, I don't know what some people are trying to say!

Hi!

My best airline freind knows guys at Skyway, and he said the same thing happened there. It was a night (luckily VMC) flight out of MKE, and they lost EVERYTHING. No attitude, no nav, no radios.

He explained it to me this way: the black boxes in the back that power that stuff are near each other. One came loose, and knocked into the other two, taking out all three power supplies, or whatever.

The whole cockpit went completely dark. The returned to MKE lost comm and landed without a problem.

Hello,
Just a quick question...Does this airplane have a mechanical or a digital back-up horizon? Just kind a curious if in the case of the Skyway bird, if they lost the back-up ADI? I was under the impression that this instrument is powered by an independent power source (It's own DC battery) that will provide 30 minutes of reliable information.
In the Navy we always briefed a total electrical failure on every flight, and the aircrewman (Moi) would get in the gunner's belt and shine my "el cheapo" plastic flashlight on the HAC's ADI, which may or may not be spinning down due to an interruption in power. This was in the older, all analog H-2. Conversly, in the H-60, this scenario was less likely due to the redundancy built into the aircraft, with the exception of the DDU all components are independent.
In retrospect, it is amazing how many failures or scenarios are called "impossible" by the engineers, yet still manage to find a way...Recall the Eastern L-1011 that had all three engines nearly run out of oil because of a .10 cent O-ring not being replaced on the accesory section drive chip detector... HAd a bit of the same happen to me in an H-60 with not nearly as uneventful an ending...In the words of Ernest K. Gann "Fate is the Hunter"

Kaman:

I think I understand what your asking. If you lose just one screen, you have your reversionary panel to switch things around. If you lose total power, you have your backup attitude indicator which I believe is powered off the essential bus. If you do have a total DC failure, you still have your TRU (transformer rectifyer Unit) to power the essential bus only from the Alternators. Even though you lose your DC power, you still have your engines running to provide AC power and the TRU turns it into DC to power the essential bus. That system has a 80 minute max limit if you pull all the circuit breakers that the QRH calls for.

If these guys did lose all the screens, im sure they got them back up fairly quickly using the TRU. These airplanes do have alot of electrical gremlins. Im sure the jet is the same way. I also agree with you about the engineers saying nothing is impossible.

If its mechanical or electrical, it will break sooner or later.

Im not sure if thats what you wanted to know.
