DANGER —-------------- 1.25 Inches Per Second (IPS) Peak Amplitude. The propeller should be removed and a static balance performed.

VERY ROUGH —------- 1.00 Inches Per Second (IPS) Peak Amplitude. Propeller can be dynamically balanced; however a large amount of weight will be required. A propeller static balance is recommended. Operation at this vibration level could cause damage.

ROUGH ----------------- 0.50 Inches Per Second (IPS) Peak Amplitude. Propeller definitely requires dynamic balance. Long term operation at this vibration level could cause excessive wear.

SLIGHTLY ROUGH -- 0.25 Inches Per Second (IPS) Peak Amplitude. Dynamic balance will improve passenger comfort, and equipment life.

FAIR----------------------- 0.15 Inches Per Second (IPS) Peak Amplitude. This is the maximum acceptable vibration level after dynamic balancing.

GOOD -------------------- 0.07 Inches Per Second (IPS) Peak Amplitude.  Victory’s dynamic balance performance guarantee of .07 or better. Work performed using digital balancing vibration equipment.  Vibration levels below 0.07 will not be detectable by pilots or passengers.
