It is even more clear now with the update that we are to enter the T.O Shift. Under DSC-22_20-20-10 P6/8 they have removed the reference line "if GPS not primary", so that would resolve any previous different interpretations from some guys that we don't have to do so.
Besides that, supplementary procedures now come under the normal procedures tab, FCTM has been reorganised completely, FCOM abnormal procedures section tabs are also reworded completely.
