Cough , Denti ; the FDM or FOQA alarm is usually a CAT 1 event which is usually monitored for trend and needn't a report or other action , and of course could be tailored and modified regularly according to airlines operational procedures and SOP's , I agree fully .
And I don't argue flying airline SOP's and following operational directives .
I am explaining technically and aerodynamically the aircraft proper landing configuration with both the standard and the SFP NG's ( Never flew classics )
Defined by the position of the LE Slats position in relation to the trailing edge flaps position with the different NG variants , which may clarify the requirement for some variants to select flaps 15 after having three greens and having this as an Airline SOP to stay within the proper Aircraft landing configuration
Which was the question at the beginning of the thread .
