Dennis,
My rationale for using a circuit breaker on the hydraulic pump
is to be able to power it down in flight if needed. There are several hydraulic/electrical
system failures that will cause the pump to run continuously. This will destroy
it in pretty short order; hence the ability to power it down if it tries to
keep running… The trim system was the only other thing that I thought
about powering down if a component failed, but I put that one on a switch.
