The present invention is a method of deriving a ground speed of an aircraft on a descent along a flight path. A vertical speed signal is produced as a function of an altitude signal and a vertical acceleration signal. The vertical speed signal is transformed to a nominal ground speed signal based upon...http://www.google.es/patents/US6492934?utm_source=gb-gplus-sharePatente US6492934 - Method of deriving ground speed for descending aircraft
