Aerospace Avionics – 14AE72 dr gemson, IIAEM, JU, Bangalore1Objectives:To provide a good foundation to understand the aerospace avionic systems Expected course learning outcome:At the end of this course the student should identify, formulate and understand the basics of avionic systems

General introduction to Avionics:The term "avionics" is one which defines the application of electronic principles to equipment used in aerospace; in fact the term may be considered as a contraction of aviation electronics. Thai is a word derived from the combination of aviation and electronics. It was first used in the USA in the early 1950s and has since gained wide scale usage and acceptance. dr gemson, IIAEM, JU, Bangalore2

In its turn, "electronics" may be considered as a designation of equipment incorporating either electronic tubes, transductors, transistors, silicon diodes, etc. and software associated wherever applicable and performing such functions as signal amplification, phase discrimination and computing of in-flight data.dr gemson, IIAEM, JU, Bangalore3

dr gemson, IIAEM, JU, Bangalore4Need for the use of avionics system:Weigh saving through crew reduction (Civil aircraft & Military aircraft)Reduction in pilot workload Multitude of functions to be carried with safely and efficientlyAll weather flight requirementsIncreased air trafficHigh performanceLight weight & small sizeetc.

5It should be realised that many of the uses of avionics are as alternatives to electro-mechanical technologies.However, avionics can do things which were never possible with other technologies which would have needed, such as excessive development times and complex, heavier in weight, occupying more space, not easy to set-up and run systemsOne of the most important functions of avionics is the presentation of data to a pilot when human senses,such as direct vision, fail because of poor or zero visibilityat night or in rain, snow and fog.dr gemson, IIAEM, JU, Bangalore

Avionics in Civil aircraft are: For better flight control, performing computations and increased control over flight control surfaces. For navigation, provide information using sensors like Attitude and Head Reference System (AHRS). To provide air data like altitude, atmospheric pressure, temperature, etc. To reduce crew workload. To increase safety for crew and passengers. To facilitate reduction in aircraft weight which can be translated into increased number of passengers or long range. To facilitate all weather operation To facilitate reduction in aircraft maintenance cost. 6dr gemson, IIAEM, JU, Bangalore

Avionics in Military aircraft: in fighter aircraft eliminates the need for a second crew member like navigator, observer etc., which helps in reducing the training costs.
