I'm new to airplane learning world, and I'm trying to figure out who owns what jet company and all that stuff. I just would like to know what the difference, if there is any difference at all, is between the MD-80 and the DC-9? Are these aircraft the same? Different? I know MD stands for McDonnell Douglas, but what does DC stand for? Are they the same company? I know these questions are really elementary and basic, but you gotta learn sometime. Thanks.
 
Although I only flew the md80 for a short time I can tell you the md80 is a dc-9. The dc-9 has several different models including the md80, md90 and boeing 717. So with a dc9 type rating you could technically fly all of them. As far as some of the earlier dc9 models someone else will have to enlighten us. The MD stands for McDonnell Douglas and the DC stands for Douglas Corporation I think.

Hi. DC stands for Douglas Commercial. The DC9 series went through numerous growth versions starting with -10s. The DC9-80 was to be called the "Super 80" but the marketing department decided to give it a new name for the '80s and thus began the MD line, starting with the MD80. It has a bigger wing than it's predecessors and an higher bypass-ratio version of the PW JT8 turbofans used on the DC9s. An enlarged center fuel tank gives it enough range to cross 3/4 of the country comfortably. Interestingly, at the MD83's max takeoff weight of 160,000lb it must exceed 250kias below 10,000' to meet min maneuvering speed, which means in order to bank more than 15 degrees. It's cruising speed is the same as DC9s although it's certified ceiling is FL370 vs FL350 for the 9.

In my purely subjective opinion the DC9 has better flying qualities than the 80.

The 717 is a hybrid version with a wing similar to the DC9-40 and a fuselage length in between the -30 and -40. It's avionics are straight from the MD11 (the updated version of the DC10) and the engines were brand new Rolls-Royce. It's by far my favorite of the three and I miss it very much.
 
I fly the Md80 and the Md90. We have alot of people in the company who have flown the Dc9, Md80 series and the Md90. They all like the Dc9for its handling, the Md80 for its Low-noise cockpit and the Md90 for its engines. In my opinion the MD90 is the ultimate Dc9, which is both good and bad.

rgds,

DC stands for Douglas Company. DC-9 is the 9th commercial transport made by the Douglas Company. McDonnell Aircraft of St. Louis merged with Douglas Aircraft in the late 60's due to Douglas financial troubles. After several accidents with the DC-10 public fear of flying on a DC aircraft was so high they decided to name all new models MD. The MD-80 is DC-9-80. The MD-80 Series includes the MD81, 82, 83, 87, 88. With the exception of the MD87, the difference between the models lies in range, takeoff gross weight and avionics configurations and thrust ratings. The MD83 was boosted to a 160KMTOW with heavier gear. The MD87 was a shrink. The fuse was shorter and the wing root plug was removed. Reno was the only domestic carrier for this one. The MD90 was a further stretch of the MD90. other exterior features include nose strakes, a huge engine plyon with a trainling edge flap for deep stall recovery and the IAE V2500 engines. It is also the only DC9 type with a hydraulic powered elevator. The 717, originally called the MD95 was just another DC9-30 with new engines and interior. Originally it didn't have the MD-11's glass cockpit but once they lost the order to SAS to the 737NG they decided they needed to make the airplane more modern and redesigned the cockpit. It turned out to be a really nice airplane. It has MD90 thrust to weight ratio, superior automation, tremendously fuel efficient and reliable.

Almost. The fuselage is a few feet longer than the -30, the gear was a brand new (and stiffer, unfortunately for pilot egos), the electrical system was redesigned, and the spoilers became spoiler-by-wire. Plus a myriad of other more minor design changes, mostly for the better. And it had that "new airplane" smell.
 
DC-9-80

The MD 80 was going to be the DC-9-80 until the merger when the marketing people wanted a new name. I think I read in my DC-3 book that DC stood for Douglas Commercial. as opposed to military.

I thought DC stood for "direct cable". :)

The company I worked for out of Willow Run sent a mech out to long beach to measure out all the cable in the DC-8. That was 1987, and he ain't back yet.
 
TWA Dude.

If we ever decide to sell our Fokker's, I hope to have them replaced with B717's. I had a tour of one of TWA's between stops, and rode in another a few weeks later, very nice airplane. I'm hoping to fly the sim at my next recurrent in Miami. With the exception of Airbuses and the B777, the 717 has got to be one of the most advanced airplanes on the current market.

The visual on the 717 simulator is amazing!! We have "2" 717 simulators in Long Beach, so I am a little spoiled....

Does FlightSafety still partner with Boeing? I heard last year that the two split but my paperwork still says FlightSafety-Boeing.
