The APU of the MD-90 was upgraded to the Allied Signal/Garrett 131-9(D) Auxiliary Power Unit. A new Internal Reference System was also installed to eliminate any compass irregularities. The engines were upgraded to the V2500-D5 from IAE and a new pylon was used to attached the engine to the fuselage. The wing of the MD-90 is basically the same as the MD-88 only strengthened.

I happen to have a book on the design of the MD-90 and such. Quite a good book. Oddly enough the book is about Airline Photography.

Isn't the length of MD-90 longer by a few feet? How many feet?


Listen Betty, don't start up with your 'White Zone' s*** again.

WMUPilot,

The book you're referring to is Airliners in Flight by Nick Veronico and George Hall. Chapter 1, "The Making of a Jetliner", covers in detail the MD-90 program. I too was surprised to see this in a aviation photography book.

Brick got me...guilty as charged....thought maybe nobody knew of the book. I also like how they have an interview with a TZ Dispatcher out of IND. Very good book.

Another good reference is "The Story of the MD-80 and MD-90." It has a listing of every MD-80 and MD-90 ever made and what airline or leasing agent owned it initially, as well as who operated it first. It was written in 1997, so it doesn't have them all, but it's fairly complete and a good read.

It also talks about the development of the MD-95 (read 717) and the original American twin-jet, the DC-9.

I do not know if there is an updated version of the book.

Cheers!

Here is the low down

The MD-88 - a modernized (a full EFIS) cockpit on an MD-82/83. Thats about it

The MD-90 - a completely new airplane that somewhat resembles an MD-88, but it doesn't, actually longer by a few feet and instead of the noisy P&W JT8D engines, uses IAE engines, somewhat quieter.

Intresting, I thought the engines where the only things that seperated the two types. I also thought that both modles appeared at the same time, so can anyone tell me how many years their are between the types debut. Also does Delta still fly the 90s ?

The MD88 first flew in 1987 and is basically an MD82 with new avionics and interior fittings. It was largely built at the behest of Delta, with just a few other carriers using the type. The MD90, by contrast, is a newer type with stretched fuselage, new IAE V2500 turbofans and further upgrades to the avionics suite. The tailfin is also of the taller type as first featured on the MD87. The MD90 first flew in 1993. Production of the MD90 ceased in 1999 while production of the MD80 ended in 2000 - interestingly the MD83 was the last model built, the last being an order of 16 for TWA.

Two good books covering the development of MD-80/MD-90 are

Thomas Becher: Douglas Twinjets (2002), hardcover, 192 p
Arthur Pearcy: MD-80 and MD-90 (1999), paperback, 128 p

The latter is available in a U.S and a British version. You will find the books at any good aviation book store, Amazon or through my MD-80/MD-90 website.

Don't forget that the MD90 started off as having rear engine props on the back, until there were no takers for the new concept.

I remember that when Delta ordered the MD-88, one of the modifications over the earlier MD-80 models was that the -88 be adaptable for later conversion to prop-fan engines.

I am curious as to why if the MD-88 has an upgraded interior and some cockpit avionics, then why were the last models to be built MD-83's?
TWA is the owner of the last MD-80's built.

You are right, the last MD80s built were the MD83 for TWA.....all members of the MD80 family were build concurrently and TWA, which bit by bit built a large fleet of MD81/82/83 aircraft with new build and second hand aircraft, stuck with the "earlier type" and did not opt for the MD88 with the upgraded cockpit. I assume that TWA did not want to introduce an additional sub-type to its fleet.

About TWA - it could have been that the additional range of the 83 made it more desireable. Remember, the 88 has more or less the same range as the 82 (ie same fuel tank capacity).

No one answered the question about how many M90's are left in the Delta fleet.

Anybody have the skinny on that?

Md80forum:

Ah, you've corrected the title I recommended. Thank you.

Flyboy80:

Last I had heard, YX had only one MD-88 in its fleet. If anyone has any updated information, please let me know.

GoldenTale737:

I believe I read in another thread that DL operates all 16 of its MD-90s. Once again, any updated information would be appreciated.

DL still operates all 16 of it's MD-90s, many if not all have gone through their first HMV. FYI- the V2500 is also a FADEC engine. MD-90 also has audio and video, which the MD-88 does not. The toilets on the MD-90 are also vacuum type.
