PROPELLERS
GENERAL
This section describes the propellers and
the associated system. Location and use of
propeller controls, principle of operation,
reversing, and feathering are included in
this discussion.
PROPELLER SYSTEM
This section on the operation and testing of
the propeller system on the Beechcraft King
Air C90GTi and C90GTx is directed at in-
creasing the pilot’s understanding of the the-
