Abstract

Successful implementation of the free flight concept requires new technologies, associated procedures, and standards for the flightcrew, the air traffic service provider, and, where applicable, the dispatcher. This paper explores several cockpit technologies and procedures that enable free flight. These enabling technologies are integrated through an operational system concept known as situational awareness for safety (SAS). SAS was intended, from its onset in 1992, as a means to communicate effectively between pilots, controllers, and dispatchers a wide variety of pertinent information relevant to safety and efficiency of flight. SAS-related information deals with the aircraft's external operating environment as well as aircraft 'status' information. Both elements are critical to the pilot's decision-making process. Initial 'core' SAS applications include: sharing of satellite-based position-in-space and other data between nearby aircraft as well as the air traffic service provider; data-linked graphical and textual weather and airport capacity/delay information to the cockpit (i.e.,'weatherlink'); and onboard terrain data files from which to create '2D' terrain overlay and '3D' dynamic image displays. Both the '2D' and '3D' displays provide predictive controlled flight into terrain protection. There software applications, along with the necessary data links, will help make free flight a distinct technical possibility.
