Sensors Used in Flying: A Comprehensive Study

Abstract

The aerospace industry is an ever-growing area where the possibility to explore and achieve next-generation technology has always been a challenge. Passenger safety with power conservation has always been areas of great interest in the global aviation sector. The induction of MEMS (micro-electro-mechanical systems) and other micro- and nanotechnologies have revolutionized the area of sensors. It has helped in drastic improvements in the performance characteristics of the systems such as sensitivity, stability, service life, etc., while reducing the overall size, weight, and power requirements. These systems are now being used aboard aircraft for various specific applications such as autopilot systems, navigation systems, etc., which were traditionally controlled manually using mechanical and electrical systems. This chapter aims at discussing traditional flight instruments and the recent advancements that have occurred due to use of MEMS. Also, we have discussed AVS (air vehicle systems) which are miniature forms of aircraft used for several specific purposes including military operations. The requirement for these vehicles in miniaturized navigation, power and communication systems can only be achieved using MEMS and other micro- and nanotechnologies.
