So I guess two wrongs do make a perceived right? Will the aircraft catch the fact we have flaps 1 but require 3? Let's make it interesting and say this is Burbank with a flex takeoff.
Even as the FO, I'm going to take a quick look at the WDR to verify the line the CA selected, especially if he's manually entering stuff on the perf page. In your example, the big question in my mind is why didn't he take the second line on the uplink?
