A rather popular optional break system that you will find installed in lots of King Airs is Brake Deice. This system is only offered on King Airs with dual main landing gear wheels, so you will never find it on a member of the 90-series, with the exception of the F90 group, since they, like their…

In the case of the A90, B90, and C90 variants, the POH also allows crossfeed when one side’s boost pump is inoperative. This prohibition means that we are not allowed…
