My apologies for ruffling a number of feathers,,
However a few statements on the last few pages of this thread were completely wild guesses, serving to do more harm than good. If you don't know the airplane, ask those who do.
I also apologise for the misleading statement about the LE flaps. I meant 4 groups on each wing, indicated by 16 lights on the FE pane, one green and one amber for each group, etc.
