For example while an important goal of most theatrical performer flying systems is to minimize the shock load or peak dynamic load on the system it is common in the circus and acrobatic industries to see measured applied dynamic loads of between six and ten times the static load Current research is being undertaken by the Ecole Nationale du Cirque in Montreal to create a statistically useful database of typical dynamic loading scenarios generated on a wide range of acts and apparatus types The standard should allow for lots of different ways of doing lots of different things But fundamentals are the same and we have the opportunity through this process to lock important principles into place Think about risks and hazards methodically Have qualified people involved in the design Understand and apply appropriate design factors including accounting for peak such as shock loads Use rated equipment where feasible and to use it within its rating Test systems and components appropriately especially where custom or non rated equipment is being used Limit access to people who know what they are doing Inspect regularly and thoroughly Have and rehearse emergency plans Maintain good documentation And so forth Finally believe that the draft standards provide a great tool to facilitate clarity and communication between performers riggers venues and presenters Here at last is a tool enabling a rigger or for that matter a performer to b

LL requires more frequent maintenance but as long as there are daily inspections daily load tests and frequent changes of the wire ropes we don t see this being an issue The most frequent use of flying effects in the USA is in theatrical productions that last less than 10 performances with the flying system installed for 3 weeks or less We work on over 300 productions annually that fit within those parameters We conservatively estimate that we cover 33 of the market so combined with our competitors in the area of theatrical flying effects Foy Hall D2 that is roughly 900 productions all with low duty cycles Our experience is that wire ropes do not show wear at the completion of these types of productions Therefore they should not be required to meet a higher WLL design factor as may be required on long or indefinitely running productions 4 the most common use of performer flying is to give the illusion of flight and this will no longer be possible in many instances despite many productions with no history of being unsafe Whereas an argument could be made that if a design factor of 8X is safe then why not go to 10X doing that would require us to use larger sized flexible lifting media which would destroy the end result of what we do namely to provide the illusion of flying to theatrical productions In stunt work the wires are digitally edited out and in spectacle flying Cirque du Soleil type seeing the wires does not distract
