I was wondering if anyone on the board knows much about the variable pivot trailing edge flap. It is a single slotted flap that uses a rotary actuator attached to the leading edge of the flap via a short linkage and a second linkage that is attached further back on the flap that connects further back on the wing then the actuator. The net result is the flap moves down and back. I know it was used on the 747SP. Seems like an attractive system as it is a simple four bar linkage and doesn't have flap tracks or exterior hinges to deal with.
