Given the range of mitigation actions possible, it is difficult to provide a quantitative estimate of both the costs and benefits of such mitigations. However, we anticipate that operators will only implement mitigations where benefits exceeds costs. As such, the FAA believes that the costs of this rule would be justified by the anticipated benefits of the rule, if adopted as proposed.
