- Best vibration damping characteristics for almost vibration free propeller operations!
- Bonded on wide chord nickel alloy leading edges for superior erosion protection of the blades!
- Smaller diameter of up to 4 inch compared to the original propeller, this means more ground clearance
of about 2 inch for less FOD and also more clearance to the fuselage, therefore less cabin noise from the prop tips!
- Take-Off improvement up to 15%, so compared to the original AFM a higher safety for the calculated take-off run!
- No propeller ADs!
- TBO 4500 hours or 6 years, whatever comes first, for low maintenance costs!
