DC-10's

Mon May 24, 1999 6:34 am

I am wondering about in particular about Northwest's DC-10's. Does Northwest fly any models other than the DC-10-40? I have noticed that some pictures of DC-10-40's are incorrectly labeled as DC-10-30's(I might be wrong about this, but here is my reasoning why). I think this, because I have noticed that the so-called DC-10-30's have the same landing gear configuration as the MD-11(nose, plus three under the body). This is landing gear configuration is not found on DC-10-30's. The landing gear configuration for DC-10-40's is only found on the MD-11 and not any other DC-10-family member. It was designed as part of Northwest's request for a DC-10 with extra range and capacity. The extra middle landing gear was added to support the extra weight of the aircraft. You can check my observation by looking at pictures of DC-10's from American and United Airlines, which operate only DC-10-10's and DC-10-30's. You will not find the extra middle landing gear. Will somebody please correct me if I'm wrong?

Well besides all that right stuff you said the NW DC-10-40 have PW engines instead of GE ones. Also the only other operator of this model is Japan Air Lines!
Take care!
CV990, the Maserati of the skies!

Sorry, but you are wrong. The DC-10-30 features the center landing gear also (along with the -40 and MD-11). Most of United's DC-10s are DC-10-10s (which do not feature the center landing gear), and American only operates DC-10-10s.

Flyf15 is correct, the DC-10-30 also has the center landing gear. The DC-10-30s operated by Hawaiian have it, and I have seen them in person.

The main difference between the DC-10-30 and -40 is, as CV990 states, the engines. The -30 has CFM International engines, while the -40 has Pratt & Whitney engines. The -40 also has a "bump" on the intake of the rear (#2) engine to accomodate the Pratt engine.

Northwest operates both types. I'm not sure of the details, but I think the original orders were for DC-10-40s, but later acquired DC-10-30s from other airlines. N223NW is one Northwest DC-10-30: http://www7.landings.com/cgi-bin/nph-search_nnr?pass=15351251&nnumber=223NW.

RE: DC-10's, Thanks Fly115

Thank you Fly115 for the corrections and new info. I just went to the United website to look for a picture of the DC-10-30, and what do you know, I saw the middle landing gear. I'm surprised I didn't notice it before.

Just to clarify everyone on this, here are the DC-10 Variants

DC-10-10: Basic Version. Span: 155 feet, length: 180. No center gear. Maximum Takeoff Weight: 443,000 lbs. Engines: 3 GE-CF6-1 & -6, each producing 40,000 lbs thst. The GE-CF6-6 produces 41,000 lbs thst. About 3,200 nm range.

DC-10-20 (Became the DC-10-40)

DC-10-30: Long-Range version. Span: 165 feet, Length: 181 feet. Center gear to compensate for increased weight. Maximum Takeoff weight: 572,000 lbs. Engines: GE-CF6-50C: producing 52,500 lbs thst. Range: 6,500 nm. Weight is primarily increased by increased fuel capacity. Note: The wings are enlarged by 10 feet.

DC-10-15: Only 7 were built, all used by Mexicana. They featured enhanced engines for Hot-n-High performance. Same dimensions as DC-10-10. Engines produce 46,000 lbs thst. Max Takeoff weight is the same, and so is range.

DC-10-40 (NWA Version): Intercontinental-Version, Length: 181 feet, Span: 165 feet. Powered by Pratt&Whitney JT-9D: 49,400 lbs thst. Maximum takeoff weight: 558,000 lbs. Range: 6,500 nm. Features a center gear like the DC-10-30.
