A fabric panel installed at the end of a canopy ,  intended primarily to reduce wingtip vortices (much as an end plate on an aircraft wing), and to provide some directional stability. Some stabilizer designs are ram-air pressurized for additional rigidity. 

Tapes, Reinforcement: A tape installed in the canopy to provide additional strength or dimensional stability. Tapes are identified by location. 

Cross Tapes:  A reinforcing tape that runs spanwise on the upper or lower surface to distribute loads through the canopy. With chordwise construction, a cross tape typically runs from a line attachment point to laterally adjacent line attachment point, although some may run from a suspension line attachment point diagonally to a control line attachment point. With spanwise construction, a cross tape may be rolled into a seam joining spanwise panels. 

Leading Edge Tape:  A tape applied to or rolled into the leading edge of a upper or lower panel. May be continuous across the span of the canopy. 

Line Attachment Reinforcement Tape: A tape sewn chordwise into a seam at a line attachment point. 

Load Tape:  A tape applied to a rib section and used to distribute the load from a line attachment to the canopy. When applied in a “V” may also be known as a “ V-tape .” In some canopies, load tapes may extend through the lower seam to become line attachment points. 

Rib Leading Edge Tape: A tape applied to or rolled into the leading edge of a rib section. 

Trailing Edge Tape:  A tape applied to or rolled into the trailing edge seam. Usually continuous across the span of the canopy. 

Toggle, Control: A grip attached to the end of the control line to allow the user an adequate handhold on the line. Most commonly consists of a tape/webbing loop or a hard plastic dowel. Typically supplied as part of the container assembly. 

Trim: The arrangement of differential line lengths to produce a desired trim angle and anhedral. See also Angle of Trim . See Figures 1a and 1b. 

Vent, Lower Surface: An opening in the lower surface to provide an alternate path for pressurization during deployment (“inflation vent”) or depressurization during flight (“accuracy vent”).
