New 206 Flight Manual Supplements Posted
Van Horn Aviation recently posted new FAA-approved Flight Manual Supplements (FMS) for the Bell 206L1, 206L3 and 206L4 helicopters on its
Documents page. The FMS’s provide new hover performance charts for each model that increase the allowable weight in ground effect (IGE) by 170 lbs and out of ground effect (OGE) by 75 lbs in Area A. Area A is the region of the hover performance charts where FAA controllability requirements are met (17 kt winds in all azimuths). Note that these charts do NOT increase the aircraft’s maximum internal gross weight limits.
The advanced airfoil design used on the VHA 2062200-101/301 tail rotor blade results in increased stall margin, thereby improving high altitude performance. Satisfactory stability and control has been demonstrated in relative winds of 30 MPH (26 kts) sideward and rearward at all loading conditions within an expanded Area A of the Hover Ceiling Charts. Each FMS provides the expanded chart and examples on how to use the charts to determine allowable weight in Area A when flying VHA tail rotor blades.
The use of VHA tail rotor blades does NOT authorize loading over the aircraft’s maximum internal gross weight limits.
