Having flown each of the key major 747 variants and engine combinations at some point through the -8, it is important to note that each of the B747's flying characteristics are typically observed by experienced B747 pilots as being good and well behaved. Notwithstanding any electronics flight deck differences, pilots typically note that the characteristics vary more within a particular variant, for conditions like very light weight versus heavy weight, or far forward CG versus far aft CG, or for a Vapp and approach trim theta ranging from Vref+5 to Vref +20 (depending on the atmospherics and things like G/S angle used)... rather than highlighting any potential differences between any two particular variant combinations. These observations usually apply to any recent 747 variant from minimum in-flight weight, to MTOGW, and well above MLW (as specifically assessed in some key flight tests), including even for the BCFs and LCFs.
