Vilas, I fully agree with you that after logging more than 20,000 hours on 300, 310, 747 and 320, landing 320 with Flaps 3 is a piece of cake. However, nowadays pilots get to land an Airbus 320 with a total time of 300 hrs with 200 hrs on Cessna 152. That is the reason why even Airbus document also state in RED INK that to maximize safety margin Full flaps landing is preferred.
