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.
Then the flaps 3 performance you think you have will all be invalid. The airplane will do what you told it to do (flaps 1) but you may not have sufficient performance for rwy wt or second segment climb since the wt data was based on flaps 3.
