The aim was a qualitative and quantitative evaluation of potential reciprocal influences in secondary surveillance radar (SSR) radio loads. This was made possible by an interpretation of the results of the radio load measurements and by an analysis of existing specifications for the various airborne collision avoidance system (ACAS). Definitive statements are impossible on account of the continuously changing boundary conditions, such as the number of active ground stations. It was shown by the algorithms contained in all II/III ACAS for interference limitations, that the performance realized additionally in the radio loads by all instruments for a maximum of 280 interrogations is limited within a perimeter of 30 nautical miles. It appears differently for ACAS I instruments, where this system is hardly active on account of high interrogation numbers. The observation area is limited to 5 nautical miles. It was concluded that the actions of ACAS II/III on the air traffic control are possible with secondary radar.
