ABSTRACT
The term avionics was coined from “aviation” and “electronics” in the 1970s. The three aspects of avionics, namely, Communications, Navigation and Surveillance, have a parallel history in that advancements in one area necessitate advances in other areas. Wartime advances in navigation and radar detection required that communications be made more sophisticated. Navigation and surveillance ideas have been combined using technology such as Automatic Dependent Surveillance-Broadcast to accomplish avionics for collision avoidance for manned as well as unmanned systems, terrain avoidance, terminal avian hazard detection, and assistance in using parallel runways. System-Wide Information Management is the key tool that is used in common with international systems to make NextGen compatible with SESAR. For both concepts, NEXTGEN and SESAR, the operations are based on shared net-centric information to aid collaborative decision making by all stakeholders and trajectory-based operations for efficient use of resources in both air and ground.
