Quoting B757Forever (Reply 48):
DL uses a tail support on the 737-900 to prevent "tail tip" (video below) Since DL unloads the forward cargo bin first (priority and connecting bags...I think???) the CG shifts aft. It is made worse as the passengers deplane because the front gets lighter while there are still passengers seated in the back..

This is correct. The airplane was so poorly designed that it requires a metal pole to keep from tipping over during unloading. HATE the 900ER.

Is United using the tail stands yet?

200 built
26 incidents
9 hull losses

In a word, yes.

The MD-11 has had problems with its flight control systems that have resulted in multiple accidents and incidents since the aircraft's introduction. The initial design of the slat/flap lever in the cockpit was conducive to accidental dislodgement by crew in flight. The defect has been corrected since 1992. In the early 2000s, Boeing improved the flight control software at the urging of the FAA to reduce the possibility of violent unintentional pitch movements.

In an effort to improve fuel efficiency, McDonnell Douglas designed the MD-11's center of gravity to be much further aft than other commercial aircraft. This significantly reduces the margin for error during the takeoff and landing phases. A number of operators have introduced special training to assist crews in safely handling the MD-11's critical phases of flight.

Oh boo hoo. Guess you didn't read the original post abiout aircraft being poorly designed because they can tip on their tails. But thanks for posting the obvious.  

Put enough weight in the back with no weight up front and just about any aircraft will tip on it's tail.

Guess you have never seen a A-321 or B-757 with engines removed and no ballast installed. The nose gear scissors extend quite a bit and tipping on their tails is just a few pounds away.

Not a loss. Nobody lost their job. Perhaps you could claim 400 weren't hired, so seniority didn't go up by 400, but no lose.

It's a loss. Any gain not capitalized upon is an intrinsic loss because you're worse off than you would have been. That's how the world works.

If you believe that DL truly will not replace those aircraft through other means, there are 400 pilots who will have to keep pushing CRJs because of it.

Hey NorthwestERW

The jet planes tip back because if you fuel the wing tanks before the center tanks, the CG (center of gravity or balance point for you non pilots) moves aft of the main gear and the plane gets tail heavy.

The 727-100 and 747 are really susceptible to fuel mismanagement while fueling.. It's a fueling issue more than cargo loading. The snow pics are another story. God did not make light snow...

Now when all the first class passengers get off a 757-300, the plane pitches back so all the weight on wheels switches on the nose wheel open and the cockpit warning lights and messages indicate weird things. Poor design, no.

The aircraft are not poorly designed, in fact they are optimized to take advantage of aerodynamics and weight distribution to create maximum efficiency . If a 100$ pole to help prevent pitch back on the ground saves 20,000 a year in fuel, it's worth it. It beats 1000lbs of lead in front of the nose gear. It's checks and balances. Study aero engineering. Lots of great stuff in there.

Cheers.

I think the 737-900ER needs some love too.   

The DL paint scheme really accentuates the droop in the fuselage. No, I'm not making it up; I used a straight edge. The section forward of the wings droops down to the front and the section aft droops down to the rear.

737-900 and 321neo / er or whatever's cannot carry full pax and max cargo coast to coast.

The A321LR can make the trip in the winter with full headwinds at MZFW with a bit of fuel to spare. It doesn't have the cargo volume of the 752 but it does have the payload by weight. The A321 CEO makes the trip with just a miniscule payload penalty. As much as people want the 752 to be better, on North American coast-to-coast routes, a recent build A321 is as good as the 752 and burns something like 2/3 the fuel.

Quoting CALTECH (Reply 67):
Put enough weight in the back with no weight up front and just about any aircraft will tip on it's tail.

True statement. What is also true is the 739 is particularly sensitive to precise loading and unloading, far more so than similar designs in similar use.

Quoting B737900ER (Reply 77):
Quoting northwestEWR (Reply 53):This is correct. The airplane was so poorly designed that it requires a metal pole to keep from tipping over during unloading. HATE the 900ER.Sorry that you guys haven't figured out how to properly unload it.

Again, the issue is not that it's not been figured out, it is that the 739 is more likely to sit on its tail than other aircraft that do the same job.

Quoting B737900ER (Reply 77):
Quoting northwestEWR (Reply 53):Is United using the tail stands yet?No. They can actually work the aircraft the way it was designed.

It's an unfortunate reality with this aircraft that loading and unloading must be done quite precisely and not always like other fleets. How different airlines handle this procedurally is up to them; it's certainly not the first aircraft to use a tailstand or require special loading considerations, and it probably won't be the last.

Quoting B737900ER (Reply 77):
The aircraft isn't poorly designed. Stop it A.net. It's the culmination of one of the best aircraft ever built. Like it or not, that's the truth. If DL ruined the aircraft, then boo DL. AS and UA figured out how to make it work, and make a lot more money off of it in the process.

Nobody is saying DL isn't making money with their aircraft, but it is a completely fair assessment to say this design is more problematic for loading and unloading than its contemporaries. I have many friends that fly the 739 at three different airlines and the BEST I can get any of them to say about the plane is "it's OK", especially when compared to the other NG models. Most are far more derogatory than that. I have flown other 737s and I absolutely detested flying them, so needless to say I'm eager to avoid ever touching the 739. They are reliable and economical and that's what the accountants that buy them like, and I have always given the 737 credit for that. As far as flying them, no thanks.

Quoting reltney (Reply 78):
If a 100$ pole to help prevent pitch back on the ground saves 20,000 a year in fuel, it's worth it.

Exactly spot on. I would also add that if the pole can save one cancellation, aircraft damage event, or injury, they are a cheap insurance policy.

Even the venerated A320 will sit on its butt. NW had one do it at DCA in the first year they flew right after the tow bar was disconnected. Load planner didn't understand the significance of a negative stab setting. FWIW it's the first A/C that I did W/B on could have negative stab setting.
Is just me, or is flying not as much fun anymore?

Thanks doc. The New 321 figures I had were wrong(av week) I see it can make it with the slight payload restriction. Again, the older 757 has no restrictions . Imagine the 757 with the new engines would be an all numbers win if they get the fuel burn down.

I flew ( not rode) a 757 on a 6 hr ATL to SAN 4 years ago due to 175 kts on the nose. Full pax and cargo and we still had fuel to spare. Hard to beat. Boeing needs to finalize the decision to re engine and reintroduce the 757 or get on the ball with the replacement.

I also flew a 737-900 ATL-SAN flight and it was ugly with less winds and about 15 empty seats. The dispatcher and I changed our alternate a few times just to barely make it. It is not a 757 replacement by a large margin either.

Cheers.
