Interesting A340-600 factoid

I was reading the current version of Wired this week. Seems the a/c
needs to get up to a speed of 180 knots ir mph (can't remember which)
for takeoff so a tail strike doesn't occur. Smething to do with the 12m
fuselage stretch over the A340-300, I guess.

The spec's I found for the A340 family don't show any difference in
take-off critical speeds for the various versions. And, it is 180 mph
not Knots.

However, the A340-600 does have additional features to decrease the
probability of tail strike on both take-off and landing due to the
long fuselage that the shorter members of the family don't have. An
additional pitch indicator and a force feedback on the flight controls
to indicate danger of tail strike conditions.

supposedly it was higher than the other A340 models but didn't specify
which one and how much by.

777-300ER has anti- tailstriek built into the FBW system. Apparently
the a/c will not tail strike no matter how hard you pull back the yoke.
Boeing claims that's good for an extra 2-5 tons payload.

I remember watching that PBS series on building the triple-seven. On one of
the flight tests they bolted huge chuncks of wood to the tail and then
"scraped" it down the runway. V. impressive.
