And don't crash into too many trees either.

Daniel Larusso

Nope. An MD-11(or most other a/c)would have stalled and winged over. Alpha floor is only available with autothrust and greater than 50' agl, Alpha prot worked just fine though.....but you knew that right?

That was indeed a fine demo of Alpha prot. Do they do that at every airshow?

The pilots of other A/C seem to have no trouble flying over trees without stalling, but you knew that, right?

Airbum

The MD11 is no i took the short bus to riddle whilist my daddy paid and paid and paid and looky here now i'm a pilot.

she's a demon horse u have to ride through the gates of hell onto that icy runway bucking the whole time. While she is throwing in prof tricks,opps no fuel readings and who needed those damn slats anyway those are for jerry's kids. Bad lighting, a cockpit that dont ask, it just starts doing stuff, and a fmc with the intuitative nature of imagenary numbers combined with the secert workings of a woman's mind.

Is she safe........ hell yeah, as safe as the hot chick who jumps in your car ,parked outside the bank ,holding a large bag, a .45cal, and screaming "step on it baby we are rich!!!!!"

All those senior to me should consider the friendly docile easy rather sluggardly boeing things and well if u have to the euro trash. I wont tell

The taught technique is to just override the A/T's in the flare. Number one, this requires only one hand on the yoke, in a big airplane in a crosswind. Number two, and this one is about to get real interesting given a certain recent event: WE ARE OVERRIDING AN AUTOMATIC SYSTEM WITHOUT CLICKING IT OFF FIRST. I can think of few habit patterns that are more dangerous to develop. Remember the crew going around in MEM after a bad autoland? Remember SFS last year?

I agree with everything you said except that a very good argument can be made that overriding the A/Ts allows just as much control with the added benefit of speed protection if you get distracted and the immediate and automatic setting of G/A thrust at the touch of a switch. Aircraft with windshear protection will also get the throttles up with the A/T switch engaged and the G/A switch. I am not familiar with MD-11 systems, but this is true of Boeings.

Daniel Larusso

That comment makes no sense, the a/c did not stall without the alpha protection it or any other a/c would have stalled-basic aerodynamics. The reason they didn't stall is because the alpha prot limited the pitch to L/D max. Alpha floor is a completely separate system that adds Toga power if the energy situation gets out of control and you haven't done it yourself already. That protection is removed at 50' agl which makes sense because it could come on during landing if someone held the plane off too long and got slow. That situation resulted from a lack of sa, planning on the fly for the airshow, and lack of systems knowledge. I'd like to see those other a/c clear the trees without stalling with full back yoke and engines at idle(until the last second). Doesn't make the Bus better, again it's just basic aerodynamics. You don't have to like the plane, but too many people comment on it without knowing jack about it. As far as the autothrottles go, can't speak for MD products but IIRC in the Boeings if you hit the Toga button with the FD and AT off, you get the pop up FD and something like 90% of GA on the first push and all of it on the second push. Don't know about the A300, but the 320 is simple, just push the thrust levers into the TOGA detent and you get it all regardless of AT status-in fact anything over the CL(MCT single engine) detent is outside of the AT engagement range.

Huck

I'm on the road - let me get back to you after I've read a few things from the systems manual on the next leg. I want to say TOGA always engages the A/T's, but not quite sure. Low speed protection is there whether or not they're engaged, also.... Anybody else with a better memory?

Now THAT's funny!

Worldguy

Huck,
If AT are switched off, AT will NOT engage by pressing the TOGA button, you will get go around guidence on the FD. Slow speed protection and WS protection will engage the AT.

just not the gear! but fdx bus tails do stay on..."knock on wood"

Huck

Thank you Worldguy....

I was first taught on the MD11 by a bunch of (ex)World guys, by the way.....
