Because it is not crystal clear on the subject, sweetheart. That includes AFM, L%B Manual, OM-A, FCOM, CCOM, and various training programmes. In fact, I may be even trying to polish one of them.
I "heard" there's max limitation and tried to get hands on it, but PPRuNe friends only had an FAA one.
http://www.pprune.org/forums/showthread.php?t=268646 If the total limit was 220 as I am led to believe, this would mean no jumpseating on full 220Y aircraft, or no infants. The only thing to be found in my books is 4x flotation device to accomodate up to 55 pax, however this is theoretical number because none of 7 required crewmembers gets seat, and even so, if operating over terra firma, can you seat more? Or not?
