It's very easy to land, very mechanical and similar to a heavy 727-200 in the flare. One thing that makes the "11" tough is the mission. Two guys, flying metric China on L888 trans-Asian with difficult sleep patterns is a challenge.

Also, while there have been isolated accidents at other smaller carriers (2 that I know of, china and the recent Russian carrier) there have been NO accidents at airlines that flew them FOR YEARS - AA, DL, UPS, Varig, Finnair, Swissair, World, Lufthansa...etc (elec fire notwithstanding). The problem, I believe is the stark difference (not difficulty) between the MD-11 and the MD-10. The problem here is the common type. We are the only airline when compared to the aforementioned that have guys bouncing from MD10 to MD11. You have folks that may:

1. Fly an MD-11 international for years (due to high seniority and Int'l preference) then get drafted for a domestic MD-10-10 trip to Denver or SLC in Wx having not seen a -10 for eons.

2. Conversely folks that can't hold international and are very proficient in the MD10's feel getting launched internationally in a heavy MD11 that they last flew long ago.

3. RFO's or junior Capt's that have flown neither for quite some time and have developed NO FEEL.

So, if our new VP of flt training/stds is watching, here's one line guy's recommendation:

4 month international bid cycles that are posted and bid on. The successful bidders will ONLY fly MD11's, period. Upon successful bid award, you come to MEM or ANC and get two hours of bounce and go's in the sim, no jeopardy, and paid for by the company as training on a day off. Snapshots from the marker inbound with every weight, CG, and wind imaginable with the instructor highlighting differences. When you rotate off the 4 month international bid and go back to domestic, you do the same thing in the MD10 sim.

The problem is the DIFFERENCE between the beasts coupled with our system form and scheduling history.
You're not making sense. It's MD-11's that are crashing. If the common type is the problem, then why aren't guys from ANC crashing MD-10's when they do one leg in an MD-10 every six months? Because one airplane is more dangerous than the other - period. Data is data. You need only compare accident rates. It's abnormally high per flight hour on the 11. Now, factor in that it flies the long haul and evaluate the data per "operation". Off the charts.

You are the only pilot I have ever heard compare it to a 727. The thing is, you can dribble the 727 down the runway, pound it into the concrete, land it in a crab - downwind gear first, and then taxi to the blocks. Do any of those individually in an -11 and chances are that somewhere in the sequence a main gear strut collapses or a wing spar fails and you're on fire and on your back.

I ain't making this stuff up - you can read about it all over the net. Can the airplane be flown safely - of course. Is it as good (safe) a design as other airplanes in its class - absolutely not. Clean maneuver speeds of 290+ are not indicative of good design.

Unless....of course it is a T-38!

I laugh when I see people saying that the MD-11 is harder to fly than any other widebody out there. Especially when everyone at FedEx comes from challenging backgrounds of some sort. UPS doesn't have these problems, do they? And please let Flight 80 rest in peace. It's a challenging job we all do and conditions got the best of two of the best.

It is amusing the way we train, to a very low level of math/engineering.
The MD-11 has the highest approach speed of any 121 airplane. High MVsquared = more energy=harder to land.
If you can find a lift diagram you will see that the MD-11 lift curve drops off drastically at just a few know slower than approach speed. If you lose speed due to any reason, your vector heads down. Gear, wing spar, LSAS, tail strikes, elevator size, and other issues make recovering from a big sink different from other airplanes.
I do believe we have over-simplified landing technique and there is good info being put out now by standards and RGS.

So if you are on speed at say 100 ft, and then add crosswind controls just as the aircraft chops the power at 50 ft, you probably will find yourself in a world of hurt?

Yes, that would be bad.
By procedure we are supposed to input crosswind controls before 100 ft. but I have found myself behind the airplane a few times.
Crosswind controls affect lift in a big way on a high wing loaded aircraft.

Which is why our technique of adding ZERO knots until you get over a 20KT Xwind adds to the problem. So, for a 30KT Xwind you are only adding 1/2 stdy state, or 5 kts to a jet that only uses 5kts above Vref? That is a problem in my book. You are right, in any aircraft, you cross-control, you add drag to the equation and with just 5kts to play with and a reliance on auto-thottles, you could be in trouble quickly. I'll take some extra knots like the good old days, you know, for Grandma, the kids, the dog....

Pipe,

It's you that isn't making sense. What's the Vclean speed for a loaded B747? How about for a loaded DC-10-30 or -40? Over 250KTS, but that has ZERO to do with it.

You must not have been listening when they told us WHY MD11's break on landing. As much as you'd like to think it's the approach speed or a design flaw in a strut or a spar, you're wrong. It's not a hard landing either. It's how you RECOVER from a hard landing, or not. The EWR crash and NRT crash are because the elevator was unloaded during a bounce recovery. Period. Quit trying to make it appear that the jet is made of balsa, it isn't.

Unload the wing of a 480,000 pound ANYTHING and hit terra-firma on one gear and I'll bet it breaks too, unless the wing goes first.

Don't be too sure. Too much energy can be bad as well and cause unexpected outcomes in all the areas mentioned.

Which is another can of worms. Cross-wind controls in before you enter the flare. Sure would be nice if we had the choice on that one.

How many times have you had a cross-wind drop off to nothing in the last 200 feet. But we're forced to induce a significant amount of drag, change power settings and aircraft attitude in the last 200 feet all because there may or may not be a cross-wind by the time we get to the touchdown zone.

This is supposedly because someone thinks it's too hard to kick the nose around and drop the wing in the flare? Not really.
