Speak Softly But Carry a Big Stick
If noise is a concern in your neighborhood, fly neighborly with VHA tail rotor blades. VHA’s composite 206/OH-58 tail rotor blades can lower the overall aircraft noise by up to 40%, according to FAA-approved acoustics testing. The noise reduction comes from a thinner NASA-designed laminar flow airfoil and shaped tip that cut through the air more efficiently than previous designs.
The VHA 206/OH-58 blades also produce more tail rotor authority, especially at higher altitudes, giving your pilot more control when it’s needed most. The more efficient blade also results in greater lift capability, as demonstrated by new IGE/OGE charts in the 206L series Flight Manual Supplements (206B FMS remains unchanged, but the VHA blades allow 206B operators to fly to the existing charts). A titanium root fitting and stainless steel pitch bearings provide more strength and durability at the root/hub connection.
