Fatigue is a red herring for sure.Pilot is hardly likely to be sleepy whilst trying to recover a hot/high approach..he'd be wide awake with high adrenalin levels.No,it was either a miscalculation(ie,the approach was unrecoverable regardless of pilot technique/proficiency) or poor technique(pilot not trained how to recover from a hot/high approach).VNAV fixation and automation reliance set the trap.Get home-itis also complicates the situation.You can be fast and low or slow and high but not fast and high,not close in anyway.At 10 miles,you can be 5000' and still meet SOP's @500 providing youre fully configured and no tailwind.Applicable to B737.
