WEIGHT-SHIFT CONTROL AIRCRAFT Powered aircraft with a framed pivoting wing and a fuselage controllable only in pitch and roll by the pilot’s ability to change the aircraft’s center of gravity with respect to the wing. Flight control of the aircraft depends on the wing’s ability to flexibly deform rather than the use of control surfaces.

WIND CORRECTION ANGLE Correction applied to the course to establish a heading so that track will coincide with course.

WIND DIRECTION INDICATORS Indicators that include a wind sock, wind tee, or tetrahedron. Visual reference will determine wind direction and runway in use.

WIND DRIFT CORRECTION Correction applied to the heading of the aircraft necessary to keep the aircraft tracking over a desired track.

WIND SHEAR A sudden, drastic shift in wind-speed, direction, or both that may occur in the horizontal or vertical plane.

WING A ram-air inflated and pressurized fabric airfoil that produces the lift necessary to support the powered parachute in flight; including the lines that attach to the cart. Also called a parachute, chute, or airfoil.

WING LOADING The amount of weight that a wing must support to provide lift.

WINGSPAN The maximum distance from wingtip to wingtip.
