Abstract : I.L.S. reflection interference should properly be considered as a feedback term in the study of control systems for automatic landing, but for convenience it has always been treated in a simpler open-loop fashion. The paper reports a qualitative study of the consequences of this simplification and finds them to be negligible both in control system analysis and in beam calibration procedures. (Author)
