Hi Everyone,
To answer your question as to whether the aircraft compares the Flap setting and THS setting, the answer is YES. When you press the T.O CONFIG test as part of your SOP after obtaining cabin clearance, an ECAM MASTER CAUTION will be generated if you have not entered the flap setting and trim setting in the PERF page as the aircraft does not have a figure to compare the actual setting of flap and trim. For reference you can refer to FCOM 1.31.15 (Indicating/recording systems) under configuration warnings.
Hope this helps
