AVIONICS AE 2401

About the Course

Avionics engineers work in the aerospace industry. Their work encompasses tasks

related to designing and programming electrical systems on board spacecraft, aircraft

and satellites.

Avionics engineers provide computer system support for all communication, navigation

and guidance systems and perform testing to ensure that those systems work properly.

Avionics Technicians have the opportunity to work with the modern avionics systems

fitted to our fleet a fixed wing and rotary wing aircrafts, including the recently

upgraded maritime and reconnaissance aircraft and the new medium helicopter.

INTRODUCTION

• Avionics are the electronic systems used on aircraft, artificial

satellites, and spacecraft.

• Avionic systems include communications, navigation, the display and

management of multiple systems, and the hundreds of systems that

are fitted to aircraft to perform individual functions. These can be as

simple as a searchlight for a police helicopter or as Complicated as

the tactical system for an airborne early warning platform.

INTRODUCTION cont…..• Many modern avionics have their origins in world war II wartime

developments.

• For example, autopilot systems that are prolific today were started to help

bomber planes fly steadily enough to hit precision targets from high

altitudes. 

• Famously, radar was developed in the UK, Germany, and the United States

during the same period. Modern avionics is a substantial portion of

military aircraft spending. Aircraft like the F-15Eand the now retired F-

14 have roughly 20 percent of their budget spent on avionics.

• Most modern helicopters now have budget splits of 60/40 in favor of

avionics.
