Flight Operational Quality Assurance (FOQA), or Flight Data Monitoring (FDM), has benefited flight safety in both fixed-wing and helicopter operations. The relative youth of FOQA programs has resulted in their minimal application among the helicopter fleets of the world; thus, Helicopter FOQA (HFOQA) has merited consolidation and expansion. This mixed methods design developed HFOQA analysis software via a blend of the qualitative data from helicopter and FOQA experts with quantitative data represented by a sample of de-identified digital flight data from 1,014 helicopter flights. Development of the software emphasized three domains of interest: (a) helicopter flight phases; (b) helicopter operational and maintenance events; and (c) helicopter event-related and safety/efficiency flight profile measurements. This study's resultant HFOQA analysis software has direct application to multifaceted helicopter operations (Emergency Medical Services [EMS], sightseeing, military, and others), and, in fact, has been utilized by an offshore helicopter operator in its daily operations.
