First, I'm on the 787 and a runway change means one has to run an electronic checklist before going. Now I suppose we could just blast off on a runway not in the box, but good old FOQA will tattle on us.
Having done the checklist I assure all of you it adds about three minutes to the process and that assumes ACARS send the runway data for uploading. Yes we could get the data and hand enter it, but that's not the preferred method. These days every thing is uploaded.
On the 320 hours; the SSC did not have an explanation because a 1000 hours system wide drop for one month is huge. Essentially that's about 14 lines of flying or 28 less pilots. Someone check my math, you know math done in public.
