Wind Guidelines during Dynamic Propeller Balancing
Balancing in a breeze can be challenging!
Here are a few wind guidelines for dynamic propeller balancing your propeller in a breeze while using the ACES Systems ProBalancer Sport, ProBalancer, Cobra II or Viper II analyzers.
Wind speed should be limited to 20 MPH (17 Knots) with a gust factor limited to 5 to 7 MPH (4 to 6 Knots). Attempting a balancing job in wind stronger than this will be very difficult if not impossible.
Do not position the aircraft next to any obstructions when the wind is blowing more than 5 MPH. Air turbulence around the obstruction will cause uneven air loads on the propeller and balancing will be more difficult.
Always face directly into the wind.
Never balance with a crosswind. Wind at even 30 to 40 degrees off the nose will cause problems and the balance results may not be as good.
Never balance with a tailwind. Wind over the tail of the aircraft affects the “Blade Pass Vibration” which in turn affects the propeller at turning speed. This situation will lead to inconsistent reading and many runs.
