Rammel,
Your can adjustment for the 76 has me tossed completely.
(a) don't the cans get run over a weighbridge prior to loading ? .. ie any tare adjustment is figured automatically in the procedure
(b) not having an underfloor plan to hand I am in the depths of ignorance here .... are the LD3s loaded symmetrically ? ... and why the need for a MTOW adjustment to meet a lateral requirement ?
Would be quite interested in your comments ... perhaps I might have to give one of the weights engineers a call to lift the cloud of confusion in my tiny brain .....
