A fan variable area nozzle (FVAN) (42) includes a flap assembly which varies a fan nozzle exit area through a cam drive ring (58). The flap assembly generally includes a multiple of flaps (50), flap linkages (52) and an actuator system (54). The actuator system (54) rotationally translates the cam drive ring (58) relative an engine centerline axis which results in a follower of the flap linkage (52) following a cam surface (86) to pivot each flap (50) such that the flap assembly dilates about the circumferential hinge line. Rotation of the cam drive ring (58) adjusts dilation of the entire fan nozzle exit area in a symmetrical manner. Another cam drive ring (58' Fig 5A) includes a multiple of movable cams (84) which engages the follower of the flap linkage (52) of each flap (50) such that pivotable movement of a particular number of the multiple of movable cams (84) about a respective cam pivot results in vectoring of the FVAN (42).
