Although line experience has shown me that F3 results in greasers if the right technique is used, Airbus has something else to say regarding "quality of touchdown".
From PRO-SUP-27-20 P 4/6
"fairly flat" - I'm guessing something close to 0° but I'm not really sure.
I am for using F3 whenever conditions permit, but I'd like for this technique to be covered in the simulators to build confidence among pilots to use F3.
Just adding another angle to this (already interesting) discussion.
