Polar,
I'm with ya' man...It's seems like being proactive, and having a bottom-up review of safety and operations is alien to this industry. After all, you are the end user and any changes should reflect your needs and inputs to operate as efficently and as safely as possible. However, the FAA charter of supporting air commerce AND safety are always in direct conflict with one another. In some cases the FAA yielded to pressure, and made some changes that have yet to really be proven effective. Specifically, the 737 rudder(US737 PIT) and fuel tank (TWA 800) are all examples of solutions that weren't supported by data. No firm conclusions were really decided in either of those accidents, but a lot of money was spent to satisfy the politicans.
We are going thru some pain at my outfit, and some of it is systemic to the industry. We will all be seeing the fallout soon, and hopefully there will be some constructive solutions to prevent another accident. I don't think that dropping the 15R/4L visual transition is anything more than the FAA "doing something". Sort of along the lines of the TSA reacting to the "shoe-bomber". Only a perception of safer skies.
