(2) LEARNING OBJECTIVES

Learning Objectives

 

The purpose of the course is to introduce students to the basic concepts of electronic sensors and their use in aircraft instruments.

 

After successfully completing the course, students should be able to:

               respond to the requirements of the international diploma Part 66 examinations on these subjects. 

               Describe the layout of the aircraft computer systems

               Explain the operation principles of the instruments and sensor systems that communicate with the aircraft computer systems.

               Explain the operation principles of the analog signal converter to digital and vice versa.

               Use transducers and analog-digital converters in the construction of flying machine subsystems.

               Εxplain the operation of basic aircraft instruments (Pitot system, magnetic compass, gyroscope, electric compass, radionavigation instruments, engine instruments, flow sensors, temperature and pressure instruments)
