The example I would like to give regarding performance-based standards, Madam Chair, would be from the approach we took on the advisory committee concerning drone flights over people, which, except for the very lowest category, was a weight-based approach.
We broke out categories based on energy per unit area. The way in which you would meet a threshold determined by the regulator—that is, the numerical value—would be open to different approaches, not restrictive in terms of technology and ways to meet that threshold through various mitigations, but flexible in that regard. In other words, it would not be prescriptive, in that you must use this technology if you want to do this kind of operation, but rather that you need to meet this energy impact threshold and you can do as you wish and invent as needed to meet that threshold.
That is an example of a performance-based standards approach in this realm.
