Aerial rigging
Aerial rigging is a specialty within the field of rigging that deals specifically with human loads. Aerial rigging is the process of setting up equipment used to make humans fly, specifically aerial circus and aerial dance equipment. The field is of critical importance, and a thorough grasp of the principles of aerial rigging is essential in order to ensure the safety of the artists and the audience. Aerial rigging is commonly practiced to different degrees by specialty fabricators, professional riggers, professional aerial artists, as well as amateur aerial artists. Most aerial circus equipment is built by fabricators around  the world that build equipment specifically for the circus industry. Aerial artists, both professional and amateur, often become riggers out of necessity. They generally learn to rig what they need. WLA (Weak Link Analysis) is the process of systematically analyzing aerial rigging for the weakest link or links in the system. WLA is the most common process used by aerial riggers to assess and improve rigging. However, it is not the only system used.
