JNTUK B.Tech Aircraft Systems and Instrumentation gives you detail information of Aircraft Systems and Instrumentation R13 syllabus It will be help full to understand you complete curriculum of the year.
Course Objective
The main objective of the subject is to study the concepts related to aircraft instruments, Instruments display panels, layouts plans and air data instruments. He/She able to distinguish different mechanisms in the different aircraft instruments. The subject also includes the different types of sensors works while the landing and take-off period of aero plane. It also helps the students to design different types of display sensors systems.
