Actually, there's a degree of interrelation between 1, 2 and 6. #1 and #2 aren't actually part of the regs, and the "at takeoff power" part is subject to quite a bit of debate. Exactly how you define the "maximum available power" for the purpose of VMC testing has been changed a few times, plus there's the option to schedule thrust with altitude (and hence provide VMC alleviation at higher alts)
