Ever move pax for W&B?

[skydiverdriver2]

Ever move them back after takeoff? I have seen this done, both on RJ's and larger aircraft. I asked the flight attendants about it, and they said the captain said it was okay. Well, we all know that burning fuel, especially in a swept wing jet, moves the CG foreward. However, the flight envelope takes this into account. You must be within balance for takeoff, enroute and landing. I hear the FAA is being very strict with this, especially after the Beech 1900 that went into the hangar in CLT. I would hate to see anyone get violated, especially for something as small as passengers not wanting to sit somewhere.

Just wanted to post a warning, take it or leave it. Have a happy Thanksgiving.

From what I understand that Beech 1900 crash had more to do with faulty mx than it did W&B. That airplane could fly over weight and out of CG no problem (so I've heard.... =)). I highly doubt it had anything to do with the crash.

 

[skydiverdriver2]

Me too. However, that doesn't stop the FAA from using the crash to justify it's actions. Have you seen the movie, "We're Marshall?" That was a depiction of an actual crash, caused by weight and balance issues. Now we have to use actual weights with non-standard groups.

I'm sure aircraft fly every day overweight and out of balance. Perhaps it takes a specific situation to actually cause it to crash. But, that is why we have rules to follow. You don't have to crash to get a violation from the FAA.

I used to do it in the E145.

Happened all the time in the CRJ200, it was nose heavy to begin with, and the gate agents always asigned everyone seats as far FWD as they could. Then wondered why we had to move them.

What did you do?

 

[Huggyu2]

We did it on a lightly loaded 727, back when I was a flight engineer.

Do you now see that you were doing something wrong?

If I remember correct, on the E-145 the CG moves aft as you fly because the fuel tanks were forward of the center of gravity.

Also, the 145 was almost always at or near the forward CG limit. So moving passengers to the back was never a problem, it was moving them forward that could become a problem.

No but I have seen the movie "We Are Marshall", and that crash was caused by the DC-9 descending below MDA on approach, either due to pilot error or an instrumentation problem. NTSB-AAR-72-11, p. 36

Not sure what movie you are talking about.

[skydiverdriver2]

Perhaps I was mistaken on the cause, thanks for correcting me. So, do you think it's okay to misload an aircraft, just because it didn't cause that crash?

All:

Most W&B programs check the takeoff and ZFW CG....so if you deliberately move passengers aft or forward without re-running the W&B, how do you know you haven't exceeded the balance envelope?

Well I think we've gotten a little sidetracked here. The question is, why is it NOT ok to move passengers back to their original seats after takeoff if you had to move them in the first place?
