I am sure if I research the regs I will find the answer, but as a known Sh!t stirrer I feel obligated to throw this one out there for public discussion.
can an aircraft that is certified for single pilot ops, but is above the magic 5700kg and thus requiring all sorts of other things by the regs, be limited to 5700KG in the operators operations manual, and therefore not require all the extras. I would imagine that although it is capable of lifting a little more( only about 400kg) it would be a pain to add to ones Ops manual due to the heavier MTOW. Is there a precedent of this being done by limiting its MTOW in the ops manual and W&B info?
