QoS validation tests for Aircraft Access to SWIM by Ground Taxiing Experiments

The System Wide Information Management (SWIM) concept has been discussed for the standardization of the data format and exchange protocol internationally in order to share the necessary information efficiently and safely in the area of civil aviation. Therefore, aircraft access to SWIM (AAtS) is a key function to achieve rich information exchange between the aircraft and ground systems. However, it is difficult for current air-to-ground communication systems to satisfy the requirement of SWIM. In this paper, we present validation test for availability of Aeronautical Mobile Airport Communications System (AeroMACS) as a wireless media to achieve the AAtS in the airport. We carried out field taxiing experiments based on the AeroMACS and SWIM prototype systems at the Sendai airport. Furthermore, we conducted validation tests of Quality of Service (QoS) function of AeroMACS for accessing to ground SWIM systems. The results show the effectiveness of AeroMACS for AAtS.
