Using situational awareness? If one were present, there wouldn't be GPWS warning. As for "data might be wrong", that's the kind of argument SSJ captain made before switching off the T2CAS blaring that aeroplane could no longer outclimb the mountain but turn away was necessary.
In hindsight, we know he was dead wrong on this one.
Basic difference between FBW Airbi and Boeing when enthusiastic pull-up is required is that in one (as long as FCS works normally) aeroplane can't be stalled no matter the pull, the other can if pilot gets overexcited.
Whether this is the factor that caused the difference between manufacturers' recommendations, anyone's guess is as good as mine.
