Borrowing a page from the commercial airline industry, Gulfstream has developed a flight data monitoring/flight operations quality assurance (FDM/FOQA) program to enhance flight safety.

Jeffrey Sands, director of flight operations for Altria, disclosed results of his company’s participation in a Flight Safety Foundation demonstration of a flight operational quality assurance (FOQA) program. Altria has two years of results from its three Gulfstream IV-SPs, using data downloaded from the airplane’s quick access recorder (QAR) sent to data-analysis vendor Austin Digital.
