Anyone see the breakdown of the tailstrike event at tulla recently and think
"eh?"
How come pilots have to put a weight into the computer?
Why doesn't this type of a/c weigh itself? This is hardly high end technical
stuff!
If it does, how come the pilots over-rode the number by so much?
WPP and kero burners, can you help?
Off- topic I know, happy to go personal

I think the DC-9 had this. Also checked C of G. Probably more
important on a short haul aircraft but maybe it is a good idea to
keep the people in the loop in case the weighing system fails.
Billy Walker has something like this in his new glider design.
As for the Airbus tailstrike, you'd think that distance makers
alongside the runway with the crew checking acceleration (speed/time
at each marker) would be a good idea. We have these markers at
Toowoomba which is unusual but it is nice to see the speed coming up
with the knowledge of how much runway is still available. The runway
goes over a hill which means you can't see the other end until close
to 1/3 of the way along or 2/3 in the other direction.
Apparently the manufacturers haven't yet been able to come up with an
acceleration checking system for takeoff. This was remarked on in a
recent news item on www.flightglobal.com
on improvements in automatic flight control systems.
