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.
TSO CERTIFICATION AND PLACARD LIMITATIONS
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
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
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.
