A320 Flap tracking fairing missing - Takeoff performance?
Recently had to depart with a Flap track fairing missing. Applied the usual fuel penalty corrections as per CDL. Company then sent paper (PDF) performance charts for us to calculate takeoff performance. The charts had no indication as to what CDL item they were to be applied for, though the document filename contained the CDL reference number.
My question is, where in the CDL or any other official Airbus manual, am I as a pilot referred to this practice of using alternative takeoff performance data for such a configuration deviation? The information provided by the CDL does not suggest I have to do this. Yet our performance manager was adamant the charts serve precisely this purpose?
Thanks
