The current regulations being proposed follow exactly that methodology. As an example, there is a design standard proposed for the construction of the aircraft itself, so that over higher-risk and complex areas it meets a higher standard of reliability.
The designs have been built on a performance-based standard. It doesn't dictate that you must do x; it says you have to come to this outcome. How you get there is up to you. We've taken that approach, and I believe it's similar, as our CTA representative mentioned at the meeting they held in the spring with the FAA, to their type of performance design standards as well.
