The way it was explained to me was, MD basically put a longer, heavier fueselage on the same DC10 wing, with winglets, but they upped the MGTOW by about 100,000 and added that pogo stick center main gear.
I know we had to advise ATC we would be flying 265 (ias) below 10,000' as that was clean speed when we departed ATL for NRT fully loaded, with the aux fuel tanks. Then we could only climb up to FL280 for the first 4-5 hours, until we had burned off enough fuel to get higher. Oh, and they said the reason for that whole LSAS system was, the horizontal stab. was too small but MD didn't want to put a bigger one on it, (more drag, more wt.), so they just tweaked the one they had. You may recall that when AA first got them, and they were burning a lot more fuel than advertised, they sued MD and won some money to pay back for the extra fuel burn. The rumor at DL was, if you bought an MD11, you got two MD88's for Free! |

The MD-11 did increase the fuselage length It has a different Wing that has much less drag The Center Gear was also on the DC-10-30 No Change. The MD-11 added a Tail Fuel Tank (and auto Tail fuel management) which gave an aft CG for better fuel economy. It actually worked very well and was required for extra long leg segments. The Fuel economy was fine, it just didn't quite have the Advertised Range when it was fully loaded. MEM (or ATL)-NRT in the winter time was about it's limit. The horizontal Stab on the MD-11 was different than the DC-10's. It was smaller and slotted and very pitch sensitive because it was further back from the CG than the older DC-10. They added LSAS , which worked well. You just had to get use to it when hand flying. It did have the highest approach speed of any Transport category aircraft that I know of. The safety flight envelope on the MD11 might be a little smaller than say a 777 or 747, but it is still a safe aircraft if operated properly. BTW many fully grossed Heavy aircraft probably have to exceed 250 "clean" on departure. It may not be a 777 but The MD-11 is a fine aircraft. It has it's quirks like any aircraft. You can easily Tail strike any Heavy Aircraft if you aren't stable. |

You wrote: "Or google "Davis Island C-17" Talk about good brakes!!!! I'm privy to info about this incident and the C-17 brakes should win an award for stopping power, probably 99% of aircraft in the same situation would be in the Bay. |

Hard to believe a guy who says he never had a bad landing in a airplane he flew for 4 years. :D Seriously once flew with a Captain who said the same about a empty Airbus 310. He then proceeded to punish the runway for the next week, made me wonder what he thought a bad landing was.:eek: |
Well as F/O on a 3 or 4 pilot crew, we didn't get but one landing a month...if we were lucky! So, I had to make each one count.
I had a really good instructor when I checked out on it (the 'milking the mouse' guy). He flew the KC10 and the DC 10, as well as the MD911, so he passed on quite a bit of his 'tricks' to keep you out of trouble. "Maintain your pitch, and don't get slow!" |

A tail strike on takeoff took out an MD-11 in PVG not too long ago. If it did indeed happen on takeoff those guys are lucky to be alive. |

Grumble,
All good points, you have my respect, I was explaining the way we land in such a short distance was utilizing the same procedures as what you guys use to land on a carrier deck with precision and accuracy consistently. But don't try to make carrier landings the stuff of mythical legend, you guys "always have a head wind, and never have to flare, you have 4 f%^cking wires, How can you miss!!":D Vito:) |

Watched the Moose guys land on the assault strips in theater more than a few times, freakin' awesome. |
