707s are actually worse than C-5s in the 'overweight for runway' area.
I just spent several weeks flying around the top end  of Australia in a
light aircraft, and the restrictions on taxiway/parking areas according to
the  CASA book  are strictly weight, there is no allowance at all in the
book for how it is spread out.  Many taxiways are only rated for 5730kg
(about 12,500 pounds), if you exceed the magic number, the pencil pushers
don't care how the weight is spread, you are breaking the regulations, and
will be prosecuted!

Reminds me of an experience a few days ago. I had a TSO'd GPS, and a flight
attendant was telling me I couldn't turn it on in the aircraft (on the

(Even though the GPS in question  was clearly certified for Aircraft use,
and the agency that makes such approvals will issue them  based  on an  FAA
TSO without futher discussion).

I don't remember the exact figure, but my recollection is the manual tells
you at Canberra, if you weigh over 30,000kg, you MUST use the runway ends
to turn around, full stop. That is simply the regulatory mentality in that
part of the world.
