Heavy landing 777

Hi a recent landing at Antigua in a 777 was very hard, and the pilot applied
the brakes really heavily, probaly in my assumption, because of the short
runway and a slight overshoot of touch down point, also if you pass the
terminal exit point i believe it would be a push back, (very expensive) as
no more exit points exist, my point is does a very heavy landing strain the
777 aircraft unduly especially the undercarriage regards Frank

Sounds like an 'autoland'. In the U.S. pilots are required to perform a
certain number of 'autolands' in order to remain current and be able to
land in conditions less than standard ILS CAT I minimums (i.e. landing
in fog). The plane is not designed to autoland itself smoothly, it is
designed to touch down within a specific spot on the runway and come to
a complete stop quickly. The software programmers were not very
interested in being smooth. BTW: In case anyone has any fantacies of
being able to land a 777 by pushing an 'autoland button', an 'auto
land' is actually much more difficult than just hand flying.

So, how =do= you do an autoland?

Yes and can it be preformed on MS FS9?

I wasn't really suppose to be your pilot today, but I did stay in a
Holiday Inn last night.

Quickly:
Arm the spoilers
Set the auto brake as desired
Check the PFD shows the correct ILS frequency and ident.
Select 'approach' when flying to intercept the localiser
Check that all three ( for a 747-400) autopilots have engaged
Check that Localiser and Glide slope are armed.

Get the flaps and speed correct using autothrust.
Monitor the engagement of Localiser and Glide slope
Monitor the approach.

That's pretty much it.

Yes especially using the new PMDG 747-400 Queen of the skies. All the
actions above (and more) work. This is very comprehensive model of the
747-400.

David, is it true that all widebody a/c are autolanded (in gen)?

The 757 autolands itself smoothly as consistently as the average pilot.
It comes to a stop quickly or not, depending on the Autobrakes setting
chosen by the crew. Is the 777 so different?

Psychologically, maybe, and naturally systems knowledge and proficiency
is necessary, but your claim of "difficulty" needs more context. What
could be easier than watching it happen, in a physical sense?

Do you have actual operational flight crew experience with the airplane?

I guess I wouldn't consider an autoland in that series "smooth" and
would challenge you to find a pilot who claims he is not smooher than
the autoland system. I would describe a 767 autoland as a "thunk" and
certainly not a greaser. Its not hard enough to drop things from the
overheads of course, but its not something a pilot would write home
about in pride had he hand flown it. I'm not sure I understand your
statement about the autobrakes. Do you have knowledge of the auto brake
setting on the flight the OP presented? As I recall the Boeing switch
has RTO,OFF,10,20,30,MAX but that's from old memory. I didn't see the
OP's description of where it was set.

You don't push a button and watch it happen. Its like saying shooting a
GPS approach is "sitting back and watching it happen" compared to an
ILS. It takes training to understand how to use your GPS system, how to
set it up, etc. It takes training to understand how to use the autoland
system.

im curious as to the claim of difficuly as well. At my carrier we only
go as low as CAT II, and the only differences between that and a CAT I
for us is a QRH monitored approach checklist and briefing, making sure
the CAT II annunciator comes up and turns green, watching the needles
and looking for lights. I'd imagine autoland w/ autothrottles (neither
of which we have) to be less work, as you no longer have to find lights
and land the airplane. More stressful sure, but i wouldnt equate that
to more difficult. Granted, i fly a certain RJ made in brazil and not
a boeing (only been up front as a jumpseater) so perhaps my perspective
is off.
