Andy,
I think that even those of us that Asmol thinks look really stupid, realise that it would be possible to load a trike so badly that it may be difficult or impossible to control.
If we go back to where this discussion deviated from the original topic, it started because somebody thought there should be weight and balance calculations written down for the particular flight.
The fact is, that if the trike is operated IAW the POH it will always be in the safe range with regard to weight and balance. The people that regulate weight shift know this and therefore don't make us do a calc for every flight, nor do they teach us how to do it ( except for, as has been shown here, the latest RAAus training syllabus, which some believe is a mistake).
If they do make us do weight and balance calcs, that is likes saying " here you go fellas, when you break the law, ( operate outside the instructions in the POH) you will need to do these calcs to make sure you don't crash".
At this stage, I don't think they do, but I will find out for sure shortly.
Bill
