Motions coming on-
Here's the rebuff you were expecting.
Yes, a 737 does have 2 CDU's but, in order for an extended ETOPS certificate to be issued it must have, amongst many other items, 2 FMC's. I am referrin to the magic box-of-tricks that lives downstairs in the E&E, and not the CDU's that us pilots type on. So, some 737's do have 2 FMC's.
