Propeller rpm is controlled by a governor
which
regulates
hydraulic
oil pressure to
the
blades. A push-pull knob
on
the control console allows
the
pilot
to select the gov-
ernor's rpm range.
lf
governor oil pressure is lost, the propeller
will
go to the
full high rpm position. This is because propeller
low
rpm is
obtained
by
governor boosted engine oil pressure working
against the centrifugal
twisting
moment of the blades.
