Whats The Difference Between MD-82 And MD-88?

Sat Nov 22, 2003 9:36 am

I know that Delta is (or was) the only operator of the MD-88, but what`s the difference between those two fine planes???

The main difference is the cockpit: the MD-88 has a "glass" cockpit. Also, as compared to the MD-82, the -88 has more powerful engines. It has JT8D-219s, which are also found on the MD-83.

Incidentally, DL is not the only operator of the MD-88. Other customers include Aeromexico, Aerolineas Argentinas, and Aviaco of Spain, later merged into Iberia.

I believe that the MD-83 and MD-88 are very similar aircraft, however the 83 has longer range capabilities. Both aircraft have glass cockpits. I could be wrong but I think the 82's have the older style cockpit. Someone correct me if I am wrong here.

i thought it went:
MD-81 = original model
MD-82 = MD-81 with more powerful engines
MD-83 = MD-82 with more range
MD-87 = shortened MD-83
MD-88 = MD-83 with glass cockpit, (and better engines/range, im not sure there)
MD-90 = MD-88 with new engines


Im probably completly rong thou, should go back to me 737s eh

I assume each advance was made in engine power, efficiency and seats as well as cockpit.

actually, can anyone explain the advances that were made, each time, in going from

dc-9

to

md-80, 82, 82, 86, 87, 88 and whatever 80 I missed

to

md-90

to

B717.

I'd appreciate it. thanks!

CanadianNorth pretty much hit the nail on the head, as far as the MD-80 family goes. Only the -88 has the glass cockpit. The MD-87, in addition to its shorter DC-9-50-length fuselage, can also be identified by its tail, which extends higher above the horizontal stabilizer than on the other models. The same tail was then used on the MD-90-30 which, in addition to incorporating an MD-88-like glass cockpit and using V2500 engines, has a stretched fuselage.

As for the evolution of the DC-9...it's late and I'm getting tired, but here goes...

DC-9-10: original short model
DC-9-30: longer fuselage, and improved wing with leading edge slats
DC-9-20: fuselage of -10, but wings of -30
DC-9-40: wings of -30, with slightly longer fuselage
DC-9-50: wings of -30, with even longer fuselage
DC-9-80: see CanadianNorth's description, above

The 717 incorporates many of the improvements of the MD-90, plus additional changes such as BR715 engines and an updated cockpit, with the approximate fuselage length of the DC-9-30.

Whew. That may not be 100% accurate, but it's reasonably close.

..... I must add that the MD87 was the first MD80 series jet with the glass cockpit.

The MD88 has a much higher takeoff weight than the -82. 160,000lbs vs 142,000lbs or something like that attributed to its stronger engines. It also holds more fuel than the -82, 49,500lbs vs thirty something giving it much longer range. Range and fuel numbers are the same as the -83, but it has the "EFIS" cockpit.

Actually, the 717-200 is closer in length to the DC-9-40 than the DC-9-30.

Starting in the late 80's MD-82's were built with CRT's like you would find in a -83 or -88.

Actually, Delta had placed orders for MD-82s, and had already begun taking delivery of them when McD announced the MD-88. DL then stopped taking deliveries of MD-82s and converted the other orders to MD-88s. The MD-82s they had were cvtd to MD-88.

FoxBravo,
just wanted to correct you that the 88 is NOT the only one with glass cockpit. MD-83's do as well and from what I understand SOME 82's. Now if you remember correctly the newest MD-80's flying today are all MD-83's which were sold to TWA. So, ofcourse the newest version made has the glass cockpit. And like I said the 83 has longer range than the 88.

You're right, what I should have said was that the MD-88 was the only one *launched* with a glass cockpit. My intent was to correct an earlier post that had implied that *all* MD-83s have a glass cockpit, which is definitely not the case--in fact, most don't. It's true that the last MD-83s off the line were built with MD-88-style glass cockpits, and others were upgraded after entering service, but these changes were made after the new cockpit was developed for the MD-88, years after the launch of the MD-83. There is a good thread in Tech/Ops that discusses upgrading the analog cockpit:

They are known as "MD" but are modifications to the base aircraft which is the "DC-9". So it is not technically incorrect to call an MD-88 as a DC-9-88 or DC-9-87 to the MD87 as those are their proper designators. I'm not sure about the MD90 I think it was certified apart from their siblings.

The MD prefix was introduced for marketing reasons and because of the merger of Douglas Commercial with McDonnell.

Codeshare....i believe your correct.

Also, AA has converted most of there MD-80's to the 82 or 83 now......i love the 83 and up's cockpits. Very nice and much more efficent.

The MD-87/-88/and -90 ARE NOT DC-9 variants. MDC purposefully cut off the DC-9 prefix for these aircraft since they were of a 'newer generation', so yes it is incorrect to call an MD-88 a DC-9-88. The DC-9 designator ends with the -83 series.

I used to think you could tell an MD-81 from the newer versions by its pointed tail cone. However, I believe some MD-82s also have a pointed tail and some have the newer 'screwdriver blade' tail cone. Am I right about this?

DeltaMD11-

I'd been wondering about this, so maybe you can clear it up for me. If the MD-87/88/90 is not equivalent to a DC-9-87/88/90, does that mean that the MD-87/88/90 are NOT the 87th, 88th, and 90th design revisions to the DC-9?

Let me try to clarify my question a bit: I read once something that implied the MD-87 was so named because it was introduced in 1987. Were the MD-87/88/90/95 so named because those were the years in which the models were announced/introduced? Or is it still a descriptor of airframe revision, just without the DC-9 prefix?

DeltaMD11... Thanks for your answer but I'm still not sure about that, (I might be wrong though). That means that the MD-88 is a completely independent certified aircraft with no legal (as far as it concerns to regs, etc) attachments to their older siblings MD83's and niners?

I remember that in the Left door frame of an MD83, it had a placard with the serial number and model of the aircraft and it said: DC-9-83; because of that and some other info I assumed that all of them but the MD90 and MD95 were VARIANTS of the DC-9 program. Please, someone clarify the terms and names under the ones, the aircraft we all know as MD83, MD87, MD88 and MD90, were certified.

Olympus I believe you are right about the tail cone, although the newer MD80s most seem to have the scredriver type. By the way isn't the MD90 longer than the MD80 series by a few feet?

OnurAir is also an MD-88 client.

The early models,except MD-87,MD-88 and MD-90,had a different tail cone.Why this change ?

To clarify a few questions posed: Quite obviously, the MD-87/-88/-90 are descendants of the DC-9 family. However, because these were of a 'newer' generation of aircraft, MDC wanted to cut it's association with the DC-9 name as it was gaining in age. Just giving the product a fresh name-if you will. Thus the DC-9 series runs through models -10 up until the -83. The -87/-88/-90 are simply known as MD-**'s, and were not manufactured under the DC-9 prefecture. I hope I'm clear with this.

Just to clarify the tail cone question: Why early MD80's have pointed tails vs. Squared off tails for the later MD models? The squared off tail on the MD 88's , 87's, and 90's is referred to as a beaver tail and is standard on those models including the current 717. It is MD made it an option on earlier MD models such as the DC-9-82. MD also made conversion kits available to customers if they wanted to install the beaver tails on their older DC-9-80's. It was standard equipment on later DC-9-83's also.

Apart from the extra fuel tanks of the MD-83,the only differences between an MD-81-82 and -83,are the certified weights.There are two options re. engines for these planes:JT8D-217A,-217C and -219.The -219 has more power than the 217A/C and can be fitted to -81's and -82's,as well.These planes were originally supplied with the pointed tail cone and analogue cockpit instruments.Starting in 1986,the beaver tailcone and EFIS instruments were introduced on the production line.All SAS MD's previously delivered,were converted with the tail cone and glass cockpit (18 a/c) and,consequently,all SAS MD's now have the beaver tail and EFIS cocpit.Other operators had the option to convert their planes.The beaver tail reduces drag by some 1.5-3 %,depending on center of gravity location.
There were no MD-84,-85 or -86.Next model was the MD-87 (DC-9-87 it says on our,SAS,data plates).217C engines,with -219 an option,longer strakes on the engine nacelles and a taller tail fin to compensate for a shorter fuselage.All but the very earliest planes have the service door between the left wing and engine deleted.Beaver tail and EFIS cockpit was standard.Could be certified at two different take-off weights,one or two auxiliary tanks was an option,too.
The MD-88 was certified as such.High weights,-219 engines and glass EFIS cockpit.It also had the possibility to be modified with prop-fan engines had these become certified.
No MD-89,next was the MD-90-30.SAS data plates state MD-90,not DC-9-90.Fuselage stretch compared to MD-81,82,83 and 88.New,larger engines (V2500D),tall fin of the MD-87 and fully hydraulic elevator controls.There are also a range of other,internal differences in electric systems,etc.The MD-90 was offered with the EFIS cockpit initially,later production planes had a "true glass cockpit",MD-11-style layout.
The MD-95 (now Boeing 717-200) was basically a DC-9 in many ways;fuselage length somewhere between the DC-9-40 and -50,DC-9-30/40 wing (albeit of newer production standards),new engines,MD-87/90 style empennage and more or less completely new systems inside.The aft,ventral stairway isn't even an option on this model.MD-11-style glass cockpit.Cockpit "eye brow" windows deleted at a later stage.
