DC-10 / MD-11 What's The Difference?

Sun Jun 18, 2006 6:55 am

Is there a difference between a DC-10 and MD-11? If so, what is it?

The MD-11 is a newer and more capable aircraft: improved wing, longer fuselage, improved avionics, longer range, etc.

Yes, the MD11 is different, several examples below:

- The MD11 has superior range to the DC10
- The MD11 holds more passengers than the DC10
- The MD11 has winglets, the DC10 doesn't
- The MD11 was introduced many years later than the DC10
- The MD11 features a EFIS flightdeck, the DC10 doesn't
- The MD11 needs 2 flight deck crews, the DC10 needs 3
- The MD11 is a 5.71m (18ft 9in) stretch compared to the DC10
- The MD11 has a modified tail with less sweepback than the DC10
- The MD11 features newer engine options from both GE and PW
- The MD11 was faster than the DC10.
- The MD11 featured a new cabin than the DC10

Both the DC10 and MD11 were wonderful aircraft, great looking also! The DC10 was much more of a sucess than the MD11 though! Unfortianatly the MD11 didn't sell well!  Sad

Although there might be some poeple on a.net who would, and probably will, disagree with me, I think that the MD-11 was a victim of the Boeing-McD merger/purchase. MD-11 sales were not going very bad, especially towards the end of its production life when many cargo airlines started to realize that it is a marvelous cargo carrier.

Some cargo operators that operate DC-10 airframes (notably FedEx) have chosen to upgrade the DC-10 flight deck to use "glass-cockpit" avionics, and a two-person flight deck like the MD-11.

Such an aircraft is usually designated an MD-10 and it allows the operator to dual-certify their cockpit crew for MD-10 and MD-11 ops.

I believed two additional reasons why the MD-11 did so poorly. The first was the fact it was delivered to customers (Airlines) withoutrncompletely correcting the software bugs with the glass cockpit. The second was the fuel consumption, from what I remembered the fuel economy was grossly under estimated. In the end it (MD-11) had to much to over come after the initial deliveries.

Not totally related, but interesting reading.

The basic difference between the two is the same as between the 747-200 and the 747-400. The MD11 could have been called the DC10-50 .. not unlike how the MD80 was originally the DC9-80...

One weird (or dumb depending on your point of view) thing I noticed about the MD11 versus the DC10 is the wingtip strobe blinks twice quick, then off, then twice quick. It was kind of annoying bouncing off the winglet as I was sitting over the wing.

Anyone else notice this on a night MD11 flight?

Great airplane though both the 10 & 11.

Absolutely correct. Look at it from the point of view of competition. Before Boeing bought Douglas there were serious talks going on with Taiwan Aerospace (who ultimately bailed on the deal), and some informal talks were had with Airbus, of which nothing came but maybe they walked off with one of those MD12 posters I saw in the early nineties....who knows where such a teamup would have gone? We'd not be arguing about who's going to get the air tanker contract.

Now. If you're in a business where there are a small number of players and the price of assembling a competitive knowledge and manufacturing base is high, it stands to reason that taking out a facility that, although outmoded, does not require a potential entrant in the field to start from a clean sheet of paper-it stands to reason that this is a good business strategy.

Boeing made damned sure that production of commercial aircraft in the United States was going to take place north of Portland on their say so or not at all.

Otherwise, how to explain letting the MD11 and the MD95 bleed to death, with no marketing support? Had they done so they'd be happily cranking out MD11 freighters to this day and people would be forking over money for the smaller jets, that had a loyal following.

But it was not to be.

And there was another reason. The hated pesky competitor had to be terminated with extreme prejudice. The SoCal beach bums had to be done away with, once and for all.

Delenda est Douglas, to paraphrase Cato.

Oh...and that stuff about grossly underestimating fuel consumption-not true. The only operator who ever had a gripe was Singapore-which is a good reason for Airbus to watch out when it comes to jacking customers around. They did not like it at all. I never heard a gripe ever about software, either, and I was there for the first fifty frames.

Thanks for the info! But it doesn't really answer my question. Seems like you'd want all these things (cept for maybe the last item) regardless of what you were hauling. In other words, I still don't see any big differentiators between a good pax carrier and a cargo carrier.

-Longer fuselage
-New wing (including winglets)
-smaller horizontal stabilizer with integral trim tank (reduces drag)
-2 crew glass cockpit
-CFDS
-Bigger and EEC controlled engines

Essentially they kept what was reliable and good from the DC-10 and improved the rest.

MD-11 strobes are (in normal operation) controlled and synchronised by a flasher-timer unit. In sequence the fwd wing strobes will flash twice, followed by the aft wing strobes once and then the upper and lower beacon. The idea is enable pilots of other aircraft to recognise from the strobe pattern if the aircraft is getting closer (two flashes means it is coming towards you) or flying away (one flash means it is flying away).
In case the flasher-timer unit fails, the strobes will flash independently in a random pattern.

Regarding the bigger #2 inlet:
I believe that all DC10-40's (Pratt powered) have it, while no DC10-10/15/30 (GE powered) do. All MD11's have the larger #2 inlet, or was it redesigned for the MD11?

It was originally introduced into the DC-10 Series 40, but later that tail inlet design got adapted for the MD-11. The Series 10/15 and Series 30 didn't have that inlet. Here for comparison (the upper left shot is a Series 10, upper right is a Series 30, and the lower left is a Series 40 while the lower right is an MD-11):

The Banjo redesign is in fact often cited as one of the reasons behind the collapse of MD.

Interestingly, the larger #2 opening seems to be a PIP (Product Improvement Package) item:
"Phase IIIB in late 1994 resulted in a drag reduction of a further 1.5% and featured an increase in the diameter of the No.2 engine intake, one of the few non-retrofittable modifications. "'
( http://www.pprune.org/forums/archive/index.php/t-46955.html )
I don't quite follow why the banjos would have needed extensive redesigning for the original MD-11, since mod work had already been done for the engines of the DC-10-40?

As I've heard it, it isn't the opening all by itself, but also the whole strut system that holds the engine pylon. Looking at the story closer, the problems may not be on the MD-11, but on the trijet MD-12 proposal. The cost of scaling up the tail engine mounting was apparently quite high. So MD found itself in a developmental dead end. But the story may be quite different in reality.

RE: DC-10 / MD-11 What's The Difference?

Nice to see all those shots of my old office, guys.

I was the only inspector on nights who'd go up in a cherry picker and inspect the fan on number 2 before a run or a flight. The others were a buncha old cowards.


There was a three story stand that went up on the tail and at the top you could look at the strobe on the top of the vertical. I got home one night and I was damn tired. I said to myself, I gave up drinkin and jackin off, why am i so tired?

I'd climbed that stand on an average sixteen times a night.

Before a flight? Every flight? You'd mean at an A check (40 hrs), no?
The official Boeing documents deploy no cherrypicker at a typical turnaround station:

On "banjo" fittings: here a two pictured. They are one-piece machined fittings through which #2 engine is fitted, and that will carry the loads of the tailfin around it.

Quoting GQfluffy (Reply 25):
IIRC, didn't this bigger opening (aka the Banjo opening) cost something like $1 billion USD to redesign and make?

I don't think that the banjo fitting was redesigned. I remember reading in Air & Space that it was the best piece of engineering on the aircraft. The materials for it weighed something like 3000 pounds (that could be wrong) and came out of the shop weighing only 500 pounds (I'm pretty sure about that). The larger inlet duct is in front of the banjo fitting, and was a way to not redesign the whole thing but still have higher mass airflow.

Plus, pilots seem to prefer the DC-10 over the MD-11, due to the -10's superior flight charactistics (not like an elephant balancing on a ball on approach...MD-11). I know Delta pilots preferred the L-1011 over the MD-11.

I wouldn't say superior and I hope one day folks will understand that after the software change about 6+ yrs. ago it flies great yes, even on approach. It's more sensitive than the DC-10 but I prefer it.

CosmicCruiser is right...the MD11 flies very good and stable and isn't that 'rocky' as the B763 which is a bit more nervous.
On top of that..the MD11 climbs like a rocket when empty or lightly loaded.
We did climb out of KRT this weekend with an initial climbrate of almost 6,000 ft/min !!

Oh, and one minor detail to determine DC10 or MD11 from head on.....the windshield wipers on the DC10 are mounted horizontal and on the MD11 they're vertical  Smile

On the flight line we'd check them before every run or test flight. It would be up in the bucket truck with the flashlight and the mirror. There was not going to be any nonsense from the customers about things that occurred after delivery.

I worked as a flight ramp QA inspector at Douglas for nearly four years mostly on the MD11 program.


Remember these were aircraft that had not yet been turned over to the customer. After they handed over the check and took the keys they could do any blessed thing they wanted to do with the aircraft.

That's good to hear. I always loved how the MD-11 looked, especially in American's and Delta's colors.

And fellows, the best ones built went to Swissair.

Swissair had their technical people on all the supply chains and they followed the components as they came together in the factory. And their technical people were master mechanics all.

When they took delivery of a new airplane they'd go to Los Angeles, take on a load of broccoli and head home. When the aircraft got homw they would pull up the floors and remove the panels and take out all the garbage they found and box it up and send it to Mr. Robert Hood the boss man....the boxes were kinda big sometimes so I heard, DAC wasn't the cleanest fab shop around.

One night this Swissair inspector comes up to me out on the ramp and says "I want you to write a DI-SR on a cotter pin that is not properly bent over." I say, fine-let's go. So up on one of the pylons we go, there's a couple of panels removed, and way back in the back there's a castle nut and the cotter pin isn't bent properly. I could barely see it with a mirror on the end of a broomstick. So I ask how he found out about this cotter pin and he says "Simple. I followed this pylon from Rohr in Chula Vista throughout its life and I tried to get those people to fix this then. Now I want it fixed for good, and you're the guy who has to sign off on it. See you later."

The next night it was fixed when I went to inspect it but G-d only knows what the day crew had to do to fix it.

That's the kind of people they had on the job.
