Read the Balance Quality graph, as follows:
• Anything better than or equal to acceptable means the propeller
meets the balance guidelines given in The Smooth Propeller.
• The label unacceptable means the balance reading is higher than
the recommended 0.2 IPS.
• The label warning indicates the propeller has a balance reading
over 1.2 IPS. The user must investigate the reason for an IPS reading
