Introduction to Avionics

Author: Mª Ángeles Martín Prats

University of Seville

Introduction

� On board systems:

- communication- navegation- identification- control, processing and storage subsystems.

� High reliability, reducing weight, volume and EMI.




Military Avionics




Concept “Avionics ”

Avionics systems� Cockpit displays.

� Communications: HF, U/VHF, satellite communications.

� Flight control system, flight control computer, auto pilot, flightdirector.

� Aids to navigation electronics systems.

� Fly-by-wire.




Avionicssystems

� Flight data recorder and cockpit voice recorder: FDR y CVR.

� Air data sensors.

� Inertial data system. IMU.

� Angle of attack.

� GPS, SATCOM.

� VOR/DME, ILS, MLS, TACAN, DF, ADF, MB.

� TCAS, GPWS.Master GSC & AIO 2011-2012
