Tipsy2,
M20E is unfortunately correct. Not that long ago there was no restriction on the number of people. Hence rich people could buy their Caravans, Citations and even Chieftans and Navajos and cart their mates around free. Not anymore. Someone told me that the change was prompted by the GA8, which can carry eight and is well within the capability of the average PPL. Sorry, I can't remember who it was that told me, so I can't verify.
