NASA said this week they are ready to start airborne tests of new cockpit technology that aims to help air traffic controllers manage landings more efficiently. After years of research and lab tests, a full airborne demo of the system is scheduled to fly later this month over Washington state. The flight crews will be using software developed by NASA that directs pilots to fly at a certain speed and maintain a precise spacing with an aircraft flying ahead of them, all the way down to the runway.
