John Tullamarine. I ask you as a moderator. Pprune has a very good reputation all over the world and there are thousands of persons involved in the aviation that comes here daily. Could we initiate a thread to get the attention of authorities, Boeing and Airbus to include the on board weight system in all the basic models? The title could be something like “To the attention of CAA, FAA, AAA, Boeing and Airbus. OB wgt & bal sys”. And the first post could be something like. “All the people posting in this message would like the onboard weight and balance system to be mandatory to all airplanes of MTOW 25000 kg or more. If you agree with this send an empty post to this thread”. Would be also very interesting if people from outside pprune could send a mail just to count on.
