Chapter 4


Chapter 2—Design and Construction, described the different types of canopy deployment devices. In some instances, the container system needs to be of a specific configuration to accommodate a certain deployment device. An example of this would be where a round canopy utilizing a Type 1 configuration is packed into a pilot emergency parachute system. In this case the pilot chute is compressed directly onto the floor of the container system. [Figure 4-49] This same canopy can be packed into a sport reserve container, but the sport rig has two internal or staging flaps that compress and hold the canopy in place and are locked together by the bridle. [Figure 4-50] The pilot chute is then packed on top of the internal flaps. The rigger needs to know and understand these differences to determine how the two components interface for compatibility.



This area is one where many riggers have some confusion. According to AC 105-2, “the strength of the harness must always be equal to or greater than the maximum force generated by the canopy during certification tests.”

In the case where the harness is certificated under TSO-C23b and the canopy under TSO-C23c, the maximum generated force of the canopy must not exceed the certificated category force of the harness and container; i.e., Low Speed Category (3,000 pounds) and Standard Category (5,000 pounds). In this instance, no additional marking on the container is necessary.

In the case where the canopy is certificated under TSOC23b and the harness under TSO-C23c, the strength of the harness must be equal to or greater than the certificated category force of the canopy.

For the current TSO-C23d, the average peak force measured during the strength drops must be placarded on the outside of the harness. In this case, the strength of the canopy must not exceed that of the harness.

All of the above areas must be considered by the rigger when making the determination as to whether a particular canopy and rig combination is compatible. If there is any doubt, the rigger should contact the rig manufacturer for guidance.
