Do I miss it yet?
We had a paper load sheet and an FMS. With children, half the weight of an adult, you could calculate 5 children on paper as 2.5 adults, but what of the FMS, since it only took whole numbers?
I once explained to an FO that he could put 2.0 adults in as pax for the equivalent of 4.0 children and then put 35 kilos of baggage as the equivalent of 0.5 adults or 1.0 children and, Sha-zam! the numbers came out right for 2.5 adults/5.0 children on the FMS!
'But, Captain, we cannot put a child in the baggage compartment! That is not allowed!'
'Err, no, you see, the load sheet is 'Weight and Balance,' when the children really are in the passenger compartment, but the FMS only shows 'Weight,' so that it doesn't matter if a child is in there as 35 kilos of baggage or not.'
'But the child cannot go in the baggage compartment. That is not allowed.'
'Umm, never mind. Just let me do the calculations and you can fly this leg.'
