One in five study reports noted "While in plain English, 'we're running out of fuel' may sound like a declaration of emergency, in the context of controller-pilot communications, where there is a specific prescribed phraseology for the declaration of an emergency, this statement would not be interpreted as such," Dr Estival said. Dr Dominque Estival, a Western Sydney University linguist, pilot and flight instructor, cites miscommunication as contributing to the deaths of more than 2000 people in aircraft accidents since the mid-1970s.
