MD87 Vs MD80'S

Wed Oct 06, 2004 8:20 pm

Hi there,

Just wondered if anyone can tell me the following differences between the MD87 and the other MD80 aircraft.

The MD87 to me seems to be a much better aircraft performance wise compared to say the MD83.
With only holding a max of 130 econ seats compared to 160 (approx) for the other, the range is much more and i thought that this kinda aircraft would be very suitable for a small charter operator.

Are the leasing cost higher for the 87 compared to the 83, what are the maintainence differences between them, are their parts compatible. Is the fuel burn higher for 87 than the 83.

Hope someone can give me some info regarding the above and any other info you feel is good.

Many Thx

sbe:
the best way to think of them is like a 733 and a 737NG. the NG has better performance because it benefits from technological advances that werent around when the 733 rolled out. So it is with the MD87 (to a great extent...there are also a few design changes I believe)

I would assume that leasing cost would be higher for the 87, but that the 87 has both easier maintenance and less fuel burn than the 83. Let's hop that someone who KNOWS can explain  Smile

You are comparing apples and pears.

The MD-87 and the MD-81/82/83 can be compared like all mebers of the 737NG (737-600/700/800/900), all part of the same family, just shorter/longer.

And because they share the same systems, wing, fuel capacity etc. the smaller variant has a better range. (just the same as with the 737NG)

There are some small design differences, the top of the fin is a little different, but that's just it. And because they have so much in common, maintainence is pretty much the same.

Leasing cost would be probably a lot defined by the market values, so it more or less depends how many aircraft are on the market.

A comparison like the one you mentioned (733 with the 737NG) would be the MD-80s with the MD-90.

All MD-80 aircraft share the same wing and more or less the same engines (JT8D-217C / 219).Wingspan 32,9m,lenght 45,1m except MD-87 which is 39,8m long. Range 2600km(81), 3200km(82), 4300km(83) and 3500km for the "baby"MD.

In fact, the MD87 introduced a number of improvements to the MD80 line. The elevated tailfin was necessary to counteract the reduced moments due to the shorter fuselage. Other improvements were the new tailcone (beaver cone), electronic 4-screen EFIS cockpit display and a few others. These changes (except the tailfin) were later introduced to the standard length planes to give rise to MD88.

Ultimately the MD87 was meant to be a direct replacement for the DC-9-30 but the longevity of the older model ultimately short-circuited sales of the 87. Just 75 were built.

One of the nice things about the 87 is that they have the same engines as the 83's which make it quite the performer with 32 less seats.

natch!!

The MD83 also had the flat sided tailcone.

The beaver cones actually made their debut on the MD87 but were subsequently standard on all later-build MD80s. Thus, since many MD83s were built after the 1986 debut of the MD87, many 83s have this cone. The cone can also be retrofitted to older MD80s and some airlines have done so.

I was told by an airplane mech that an MD-87 has apx the same fuselage length as a DC9-50..not exact but close.

They are very close.....

DC9-50 length is 133' 7"

MD87 length is 130' 5"


I think the MD87 is hot looking little airplane.............example:

"MD87 is hot looking little airplane" – somehow it feels different too. I enjoyed flying on it more than on MD82 or even MD90 – all with the same airline, SK

Where does the 87 stack up against the 717 other than the advanced RR engines on the 717. Also was the 717 a "perfected" 87 ???

Is the fuel burn higher for 87 than the 83.

The answer is yes, if you are considering fuel burn per passengers carried. MD-87 has almost similar engines than MD-81/82/83 but less seats, therefore relative fuel consumption of MD-87 is higher.

The MD-87 was designed for longer thin routes and was also an excellent aircraft for hot and high conditions due the great performance.

I wouldn't say that 717 is "perfected" MD-87 as it doesn't have as great range as the MD-87. That has been one of the biggest problems of B717 since it was introduced. B717 would have been more successfull if it would have the range of MD-87. MD-87 has also more seats than B717.

MD-87:
Range with 130 pax and reserves 4393km (2372nm) or optionally 5248km (2833nm)

717-200BGW
Range with 106 pax 2545km (1375nm).

717-200HGW
Range with 106 pax 3815km (2060nm).

Many thx for all your replies there, much appreciated.

so when we compare the md87 to say the 737-300 as they have approx same pax cap....which is more efficient and what do u think would be the cheapeast to lease and run.

once again...many thx in adv
