Changing Cruise Altitudes for Aircraft (IMAGE) Virginia Tech Caption Antonio Trani, director of Virginia Tech's Air Transportation Systems Laboratory and a professor of civil and environmental engineering, led a study that provided evidence for tactical recommendations on restricted cruise altitudes for aircraft crossing the North Atlantic oceanic airspace. The research is part of the Future Air Navigation System started in the 1990s that focused on communication between aircraft and air traffic control services.
