Perform a functional check:
1. Place cockpit propeller RPM lever in
MAX RPM position. Advance throttle
slowly to maximum permitted engine
manifold pressure limits. Record propel-
ler RPM. If local wind conditions are
over 2.5 m/s, 5 knots repeat check with
aircraft pointed to opposite direction and
average two numbers. As a general rule,
propeller should be 25-100 rpm below
the red line limit during check.
2. Pull back the propeller lever 3 to 5 times
to remove the air in the system.
See engine starting and
shut-down procedure on
AFM. Keep parking brake
engaged.
See Governor CMM
Chapter "Troubleshoot-
ing" to check, if the pro-
peller or governor limits
the rpm.
