The Entertainment Services and Technology Association (ESTA) has announced that the draft American National Standard BSR E1.7, Entertainment Technology--Recommended Practice for the Design and Use of Manual Systems for Flying Performers is available for a third public review. All persons and organizations that have an interest in the standard are invited to review it and to offer comments.

BSR E1.7, Entertainment Technology--Recommended Practice For Flying Performers describes recommended practices for lifting and transporting performers to create the illusion of flying or levitation in theatrical performances. These recommended practices cover single and multiwire flying systems that use direct human power, mechanical advantage, counterweights, or other means to lift or transport performers.

In other news, ESTA has also made BSR E1.3, Entertainment Technology--Lighting Control Systems--0 (Zero) to 10V Analog Control Specification available for public review until September 12.

The draft has been made available for public review several times before, but is being re-submitted to public review because substantive changes were made to the text as a result of each review. The Control Protocols Working Group has resolved issues that were recently raised. These include the specifying of how many analog receivers (e.g., dimmers) can be driven from one control channel, and what happens to the signal in the control cable when the controller is powered from a low-voltage supply at the receiver end as opposed to being powered from its own supply.
