SESAR and Military Aircraft: Human Machine Interface definition for 4D Trajectory Management and ASAS Spacing functionalities

Single European Sky ATM Research (SESAR) is an ambitious research program funded by European Community and Eurocontrol whose aim is to renovate the European ATM (Air Traffic Management) system toward a Single European Sky (SES). SES will involve not only civil/commercial air traffic but also military air traffic. The integration of military aircraft into a collaborative ATM environment leads to the necessity to solve the problem of making the military aircraft systems interoperable with the Air Traffic Management framework. SESAR procedures identified for a minimum interoperability level are Initial 4D (I4D) and ASAS SPAcing Sequencing and Merging (ASPA S&M) where ASAS stands for Airborne Separation Assistance System. The aim of the paper is to study the accommodation of selected SESAR functionalities (i.e. I4D and ASPA S&M) in the military cockpit configuration of Transport-type and Fighter-type. Typical military cockpit configurations have been analyzed in order to identify cockpit item which could accommodate requirements of SESAR functionalities. By analyzing military cockpit items as well as requirements of Initial 4D and ASPA S&M, a design solution has been identified in concurrence with industry military pilots.
