Didn't want to introduce this into the thread for fear of getting flamed, but as square leg has brought up the subject...
I have personally experienced problems on 777 a/c with shifting cargo pallets. CO, EK, MAS.
None resulted in C of G warnings to the flight crew. One did cause the cabin crew to report loud bangs on rotation, TOC and landing run (braking). The pallet was found to be free to move approx 15 feet from it's forward stop near the cargo door to the rear stops! Fortunately it was lightly loaded.
My point is that if a heavy cargo pallet was loaded in the correct position but not locked in place, then the resulting shift rearwards, if there was room, could cause a large rearwards shift in Cof G.
Also, if memory serves, MAS routinely need to alter the position of the cargo locks during turnrounds to accomodate different class of palletts. Other airlines may do the same but MAS are the only ones I have had to routinely assist in this task.
Just thoughts thats all.
