Abstract:Flight Operational Quality Assurance (FOQA) programs seek to use flight data to
detect technical flaws, unsafe practices, or conditions outside of desired
operating procedures early enough to allow timely intervention to avert
accidents or incidents. These programs are voluntary efforts by airlines that
involve equipping aircraft with specialized devices to continuously record up
to hundreds of different flight data parameters from aircraft systems and
sensors, analyzing the data, identifying trends, and taking action to correct
potential problems. The analysis of flight data allows airlines to reconstruct
entire flights on the basis of the values over time of flight data parameters,
such as heading, altitude, throttle settings, ground speed, and many others.
At the time of this report, about 33 foreign airlines and 4 U.S. airlines-
United, US Airways, Continental, and Alaska-have implemented FOQA or FOQA-type
programs. This report examines (1) how FOQA programs will enhance aviation
safety, (2) the costs and benefits of such programs, and (3) the factors that
could impede their full implementation and actions that could be taken to
overcome any impediments. 42p.
