I think our process focuses on the training. Line pilots who have experience operating these airplanes every day have a unique perspective on not just how the airplane is certified but also on the training that is recommended to the airlines. It's that training, that perspective, first and foremost, that is best evaluated by line pilots who do the job every day and understand best how effective that training may or may not be.
Of course, the aircraft design and operations team evaluates the information from a technical perspective, and we always think that having a safety organization such as ours with eyes on that aspect is beneficial in offering a different perspective, but it's primarily to accomplish a good evaluation of the training procedure.
