A loop of tape, webbing, or the functional equivalent, for attaching something to the  surface of the canopy.  Pilot Chute . An attachment point for the pilot chute or pilot chute bridle, including any  reinforcement to reduce the effects of abrasion, and also including any additional rib- or canopy- reinforcing tapes intended to distribute the load from the pilot chute to the canopy.  Suspension Line.  An attachment point for a suspension line or control line. Some canopies use  extensions of rib-reinforcing or flare-reinforcing load tapes to form line attachment points. See  also  Flare, Suspension Line Attachment .  Cell: The chamber formed by upper and lower surfaces and two adjacent loadbearing ribs. Drawstring: A fabric or tape channel that encloses a drawstring, most often found on main  canopy sliders. Pilot Chute Reefing: A channel that runs through the center of the canopy, from upper surface  to the lower surface, to allow the pilot chute bridle to connect to the slider. Chord:  The distance from the farthest forward point to the farthest aft point on an airfoil section. If the  canopy airfoil sections are not identical, an average chord may be specified. Airfoil dimensions are  assumed to be finished dimensions unless otherwise specified. See also  Span , and  Line (Design),  Chord. Chordwise: A construction method in which upper and lower surfaces are assembled from  panels which run from front to rear (chordwise) and are joined to the ribs and each other using a  variety of sewn seams. The most common type of ram-air parachute construction. Channel, Construction,  Line (Design),  Spanwise: A construction method in which the upper and lower surfaces are assembled from  panels that run from side to side (spanwise) across the full width of the canopy. Personnel  parachutes usually require three or four panels each for the upper and lower surfaces.  Crossports: Holes cut in the rib sections to balance the air pressure between adjacent chambers.  Drawstring, Slider: A length of tape or line which may be pulled to collapse or remove a slider after  deployment.  Flare, Suspension Line Attachment: An extension of a load bearing rib used on some canopies to  distribute suspension line loads along the lower rib seams. A suspension line attachment flare may be  integral with the rib or may be sewn to it.  Chord: A line drawn through the farthest forward point and the farthest aft point on an airfoil  section. See Figure 3.  Reference, Horizontal: A line drawn at a right angle to the Vertical Reference Line. Usage is  equivalent to the practice of using the aircraft longitudinal axis as an aircraft reference line. See  Figure 3.  Reference, Vertical: A line drawn through the links and the quarter chord point.  Page 2 of 8 Change 1 (December 2015)  A-4
