Heavy landing 777

Notwithstanding that any jet can go backwards with the use of the
reversers, why a push-back beyond the exit point - isn't the apron
there wide enough to accommodate a 180-degree turn?

That's never wise with low engines. The book may even have a minimum
forward speed for reversers.

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

If you are referring to VC Byrd, you are wrong. It is plenty long enough and
does have a turning point at the end. As for the undercarriage, it will
survive very hard landings. One of my buds has recorded in excess of 2 g's
with the only damage being to his ego. The monocoque fuselage will buckle
first. Search the web and you'll come across some pictures of a B-767 in the
Dominican Republic 2 years ago exhibiting such damage.

If you can find a copy of the TV documentary 21st Century Jet on the
building and certification of the 777, you'll see that it's designed
to take much more severe braking than what you witnessed.

Ron,
I watched the same. As I recall, the heavy braking test also resulted
in some wheel fires.
