MIL-STD-849B

3.2.19  Cap seam.  The top seam of the pilot chute, which joins the gores and the duck cloth disk together.

3.2.20  Cascade.  The junction of two groups of suspension lines before attachment to the risers on gliding type parachutes.

3.2.21  Cell.  Two adjacent air intake passages between two adjacent groups of suspension lines on ram-air or similar gliding type parachutes.

3.2.22  Channel canopy.  The space or opening through which the suspension lines are passed.  It is formed by the overlapping of the fabric in the main seams, or by the addition of cover tape to the drag producing surface, generally on round type parachutes.

3.2.23  Chest protector.  A pad fastened to the inside of the harness to absorb shock.

3.2.24  Chordwise.  The direction in which the ribs are attached on the upper and lower glide surfaces of gliding type parachutes.

3.2.25  Chordwise seams.  The seams that attach the rib panels to the upper and lower glide surfaces of gliding type parachutes.

3.2.26  Chest strap.  A harness strap secured across the chest to prevent the wearer from falling out of the harness.

3.2.27  Chute.  The term used interchangeably for the word "parachute."

3.2.28  Chimney effect.  A change in the gradual tapering of the gores of the canopy resulting in constriction between the hem and vent.

3.2.29  Clevis.  A u-shaped metal fitting with a hole in each end to receive a pin or bolt.

3.2.30  Clip, safety.  A special shaped metal fitting used to prevent the accidental opening of the parachute harness release.

3.2.31  Cluster.  Two or more parachutes that are attached to a single load and designed to open simultaneously.

3.2.32  Cone, pack.  A small cone-shaped metal post, sewn to one of the side flaps of the pack, containing a drill hole through the cone near the top.  Grommets positioned on the opposite flap of the pack are placed over the cones and ripcord pins are inserted in the cone hole to keep the pack closed.

3.2.33 Control lines.  Used to steer and maneuver canopy, also known as steering or brake lines.
