Computer-Related Incidents with Commercial Aircraft
The Benefits of Automation in Aircraft
We should not forget that the reason that automation is used in
aircraft control and navigation is to make flying safer and easier
for all concerned. While this survey concentrates on the risks,
there are examples of clear safety benefits. Nancy Leveson in her
News For a Change
notes some incidents in which the TCAS, the Traffic Alert and
Collision Avoidance System, helped avoid potential accidents.
TCAS is required by the FAA for commercial flightflights in the USA.
Leveson was a consultant for the FAA on TCAS.
Peter Ladkin in
Flight Control Systems help the U.S. Navy
notes an article in Flight International on how the U.S. Navy is
speeding up acquisition of digital flight control systems for the
F-14 in an effort to reduce loss-of-control accidents.
A very visible example of the potential benefits of increased automation
loss of a US Air Force T-43A
(a military version of the B737-200) carrying US Secretary
of Commerce Ron Brown near Dubrovnik in Croatia on April 3, 1996.
