This vehicle was certified to US FAR Part 29. The FAA website can get you to the Type Certificate Data Sheet and to the Part 29 (ie; Amendment level) in effect at the time of certification. The individual P29 requirments can be thought of as defining a "minimum level of capability", but which of them is the governing one for any given takeoff "may" not be able to be determined by the operator. Do you have acess to the vehicle's AFM or crew operating manual ? - they should have some performance data.
