Thanks, completely missed this section. However, not understanding how "Takeoff and approach climb performance limiting weights are reduced by xxx kg" implies I need to somehow get hold of alternative takeoff performance charts.. Our perf software doesn't have any CDL items in the drop down list we can choose from. If Airbus's FlySmart has the ability to select Flap Track Fairing missing as a CDL item, then I guess it's OK and this whole situation is just a function of my present company's cheap ways. All in all, just another trap for the pilot.
