This
will
keep
the

If the synchronzer is on
but
unable
to

PROPELLER SYNCHROSCOPE
A
propeller
svnchroscope. located in
the
tachometer
case,
operates to give an
indication
of
synchronization
of propel-
lers. If
the
right
propeller
is
operating
at a
higher
rpm
than
the left,
the
face of the synchroscope, a black and
white
cross pattern, spins in a
clockwise
rotation.
Counterclock-
wise
rotation
indicates a
higher
rpm of
the
left
propeller.
This
instrument
aids
the
pilot
in
accomplishing
manual
syn-
chronization
of the propellers.
