SESA6069 Avionics

Module Overview

This module is intended to develop a deeper understanding of operational principles and techniques of a variety of avionics systems including flight control, onboard communication, sensor, GPS, and radar. The module consists of two parts. In Part 1, structure and operational principles of flight control systems, flight computer, and onboard communication are introduced. In Part, basic knowledge on radio wave and its application to radar and related avionics systems are presented.

Aims and Objectives

Module Aims

The module is aimed to introduce the fundamental principles and engineering techniques used in the operation of onboard aircraft systems (and their component parts), radar and communication systems and to relate them to the current and future systems used by civilian and military aircraft.

Learning Outcomes

Knowledge and Understanding

Having successfully completed this module, you will be able to demonstrate knowledge and understanding of:

  • Radar and communication systems and techniques in use at present so that students can gain a clear understanding of the principles involved, the methods of implementation and how the systems relate to the operation of military and civilian aircraft radar. The use of countermeasures and stealth will also be covered. Future requirements will be discussed to indicate the development required of current and future radar systems. Advanced radars used for imaging will also be included.
  • How component parts, subsystems and systems are integrated into onboard aircraft systems and the communications and interrelationships between the various system elements. Additionally, critical constraints on these system, how the aircraft operates in relation them and the requirement of future generation aircraft will also be appreciated.
Subject Specific Intellectual and Research Skills

Having successfully completed this module you will be able to:

  • Understand the key factors determining the design of communications and radar systems used in aircraft
  • Apply the radar equation and set up and solve problems involving radar range, noise, and radar cross-section
  • Have an appreciation of the issues concerned with stealth, protection and countermeasures
  • Understand and identify the key components and signals of onboard aircraft systems and how they interact with one another
  • Describe different methods of detecting and dealing with the failure of components and (sub) systems
  • Have an appreciation of the properties of a range of different feasible architectures
Transferable and Generic Skills

Having successfully completed this module you will be able to:

  • Study and learn independently
  • Solve problems
