power approaches, RPM can be
controlled by a small amount of
collective pitch increase (no
significant torque increase) and/or
by decreasing the GOV RPM
switch to obtain 100% POWER
TURBINE RPM. This will maintain
POWER TURBINE RPM within
limits during low Dower descents:
however, the GOV RPM switch
should be positioned to INCR as
collective is increased. (Refer to
POWER TURBINE RPM in
LIMITATIONS, Section 1.)
3. Flight path - As required for type of
approach.
