A JFA Aviation LOSA audit provides flight department managers with early warnings of developing safety problems. One of the biggest threats to flight departments is procedural drift. Checklists are long and the clock is always ticking. The LOSA is the current procedure to address this human characteristic that no other current data collection method can detect. A LOSA is a non-punitive, unobtrusive, cockpit observation program that collects safety-related flight data during normal operations in order to assess safety margins and improvement measures.
