Advantages:

• Best vibration damping characteristics
  for almost vibration free propeller operations
• Bonded on nickel alloy leading edge for best erosion
  protection of the blades
• No engine modifications (no cam or beta tube change)
• Ground roll distance reduced by approx. 50 m (165 ft)
• Take-off distance over 50 ft obstacle reduced by
  approx. 80 m (260 ft)
• Two engine and single engine climb performance
  slightly improved by up to 80 ft/min
• Cruise performance slightly improved by up to 2 kts
• Approx. 65 lbs less weight than the orig. metal propellers
• More ground clearance for less FODs
• Significant inside and outside noise reductions
• Aircraft noise level is about 5 dB(A) less than with the
  original metal propellers
• Cabin noise is reduced by 3 to 4 dB(A)
  depending on location
• Unlimited blade life
• FOD repairable blades
