just a thought but not sure. Isn't in an NG the flap indicator driven by the flap and slat computer so the computer will give you the indication so I don't think you will get an indication like you mentionned. I think it will be in the middle of up and Flap one so maybe flap up after all????????? If the computer senses a split it will indicate an exact split via the flap indicator or do I have it completely wrong?
Just a thought I'm not sure
