Please can someone explain the differences between the MD-81,82,83,87,88?

I know that the MD87 is smaller than the other versions, but what is the differences between the other varients?

Any help would be great...

Thanks,

Rob!  Smile

The MD83 has a bigger range than the 81 and 82. The 87 is a shorter, longer range variant with new avionics (glass cockpit). The 88 is the same size as the 81, 82 and 83, but with the new avionics of the 87. Oh, the 82 has more powerful engines than the 81 (hot and high version). And of course the 81 is the baseline version.

The MD81 was the base version, the MD82 and then MD83 added more powerful engines, increased range and payload. All share the same fuselage and its nearly impossible to distinguish one from the other. Several airframe have been upgraded and converted from one type to another, ie, MD81s have been upgraded to MD82/83s. The MD80 was originally known as the DC9-81/82/83 series and AA turned that into the Super 80.

The MD87 came later, as you already know, it has a shorter fuselage, carries less passengers but has about the same range as the MD83 - it sold in small numbers (none of the big US carriers that operate the MD80 family in large numbers were interested), it was also pitched as a good aircraft for operations out of hot and high airports. The MD87 introduced an improved cockpit.....why the MD87 name, think DC9-70, although this aircraft is officially the MD87.

The MD88 is basically an MD83 combined with the cockpit improvements and some other features which were introduced with the MD87. DL was the largest customer for this type.......and actually, the first few MD88s delivered to DL were uprgraded from MD83 to MD88 standard. The MD88 is the most advanced memeber of the MD80 family.

Of course, when talking about the MD80 family, one should mention the MD90 (a re-engined, further streched, and improved version of the MD88) and the 717 (MD95) which basically took the original DC9-30 airframe and intergrated 35 years of improvements and advancements and benefited from all of the lessons made with the MD80/90 aircraft plus, of course, new fuel effecient engines.

The 717 also has a wider fuselage compared to the dc9/md80 family and a few other upgrades i don't recall exactly.

Also, with each subsequent heavier version, the undercarriage was strengthened.

"Super 80" is just a gimick/marketing name. It's also used by Alitalia.

"MD-80" is only a marketing name. It was originally marketed as "DC-90 Series 80" or "Super 80". The model numbers for the aircraft, and what you can read on the plaque on the entry door frame, have never been MD-80 until the -88:
- DC-9-81
- DC-9-82
- DC-9-83
- DC-9-87
- MD-88 (I think)
- MD-90-30
- 717

IIRC the fuselage the same but the cabin is slightly wider.

There is no DC-9-88, as McDonnell Douglas changed their name from Douglas to MDD right after the DC-9-87. So the next version, going to be called DC-9-88, got automatically named from start MD-88.

BTW, Which models (81, 82, 83, ..) have a "round" fuselage tail piece, and which ones have a "flat" one?

Its a bit confusin, for example. heres an MD-81 with a round piece

As far as I know, there is no method to the madness with round and flat tailpieces on the MD81/82/83 - most were built with the round version and some were modified/upgraded with the flat version. At a certain point, the flat version became standard (when the MD88 went into production, I am really not sure).

No - all DC-9s, MD80s, MD90s and the 717 have the same, identical fuselage cross-section.

What the 717 has is a well laid out interior that makes the cabin "feel" bigger than youyr standard DC-9. The same way the 737NG "feels" bigger than a classic 737.

I believe that's when it was too. A number of older MD80s delivered with the round tip cone have been upgraded to the flat blade cone. The MD87 was the first one to have the flat cone.

Actually, the first few DL birds were delivered as -82's and later converted to -88's.

Thanks.

'DC-9 Super 80' is more like it.. like Douglas did with the DC-8 Super 60s and 70s series.
