A general methodology for assessing interference to aeronautical safety-of-flight receivers

This paper presents a general method for establishing the allowable emission characteristics of both unwanted and intentional in-band emissions in a manner that ensures protection of aeronautical radio communications, navigation and surveillance systems. The methodology is based on a two-tiered approach, and has been used in the development of DO-235A and DO-292, as well as recent work by RTCA Special Committee 202.
