What Is The Difference Between A MD82 And MD83?

Sat Mar 30, 2002 8:45 am

Is it a difference in performance, size, etc... also there is a difference in these two aircrafts. At the back, there is a cone shaped and a narrow shaped tail just under the vertical stabilizer. Would that indicate if it is a MD82 or a MD83?

Funny, 777236ER.

Seriiously, the MD83 has a higher gross weight, and thus can carry a bit more payload or fly a bit further than the MD82. The MD88 has a more advanced cockpit I believe.......the MD81/82/83/88 are all the same size and just about impossible to tell apart when spotting; the MD87 has a shorter fuselage.

The difference is in performance - the MD83 has additional fuel tanks that boost its range considerably. Other than that there is no difference. The tailcones cannot be used to distinguish them - while the newer "screwdriver" cones came as standard on later build MD80s they were also retro-fitted to older aircraft of the series. Some MD83s thus have the older pointed cones while some MD82s have the newer ones.

Both the BWIA planes depicted are MD83s - BW only flew 1 MD82 and that was briefly, between 1984-5. IT was replaced by further MD83s. The 82 was the first MD80 type BW flew - it also took on an 83 and used it on flights to BOS and BWI. It eventually settled on the 83 and took 9 in total - now there are just 2 left.

Ah, thanks Trintocan. That explains why THN and THQ was coned shaped and the others were "screwdriver shaped" because they were the first 2 BWIA received. Thanks Again Guys!!!!

To add to this the MD88 is the only that is "officially an MD series. The MD80-83 all have DC-9-8* on their certificate where as the MD88 has MD88 on its.

ONE CORRECTION- there IS another difference between the -82 and -83.

The MD-82 has Pratt and Whitney JT8D-217C engines.
The MD-83 has Pratt and Whitney JT8D-219 engines.

The -219s are a bit more fuel efficient, further increasing the range of the plane.

It's kinda like the difference between the DC-9-32 and DC-9-34. Practically nothing, just little stuff, with the -34 being the long range variant.

The screwdriver tails are more aerodynamic than the pointy ones, but as someone else said, they are put on planes TOTALLY at random it seems...

MD-80 Engines

Mon Apr 01, 2002 7:58 pm

The JT8D-217C engine is identical to the JT8D-219.It has a slightly lower thrust rating than the -219 and can be uprated by simply adjusting a screw on the fuel control unit.The engine data plate shall be turned inside out and there's the -219 data available!Simple!
The -219 is an option for the MD-82.We have several MD-82's here in SAS with the -219 engine,so the engine model fitted is not a sure give-away as to what version of the MD you're looking at.
