Pilot error (sometimes called cockpit error) is a term once used to describe a decision, action or inaction by a pilot or crew of an aircraft determined to be a cause or contributing factor in an accident or incident. The term included mistakes, oversights, lapses in judgment, gaps in training, adverse habits, and failures to exercise due diligence in a pilot's duties. A broader view of how human factors fits into a system is now considered standard practice by accident investigators when examining the chain of events that led to an accident.
