Starting the Scan
Start the scan in the center of the PFD on the yellow chevron.
Note the pitch attitude and then transition the eyes upward to
the slip/skid indicator. Ensure that the aircraft is coordinated
by aligning the split triangle symbol. The lop of the split
triangle is referred to as the roll pointer. The lower portion of
the split triangle is the slip/skid indicator. If the lower portion
of the triangle is off to one side, step on the rudder pedal on
the same side to offset it. [Figure 4-35] NOTE. The aircraft
is not changing heading. There is no trend Vector on the turn
rate indicator.

While scan fling that region, check the roll pointer and assure
that the desired degree of roll is being indicated on the bank
scale. The roll index and the bank scale remain stationary at
the top of the attitude indicator. The index is marked with
angles of 10°, 20°, 30°, 45° and 60° in both directions. If the
desired bank angle is not indicated, make the appropriate
aileron corrections. Verify the bank angle is correct and
continue scanning back to the yellow chevron.
