Airbus submits patent for airspeed error monitoring

http://www.flightglobal.com/articles/2010/01/07/336818/airbus-submits-patent-for-airspeed-error-monitoring.html

Airbus has submitted a US patent application for an independent means
of monitoring an aircraft's pressure-based airspeed measurement for
errors.

While the process is mainly geared at determining pitot system errors
on the take-off roll, giving pilots the ability to abort a take-off
before flight speeds are attained, Airbus in the 3 December filing
also notes that "failure to detect these erroneous measurements can
have unfortunate consequences during flight".
