Introduction To Basic Instruments

Module 5 is about Digital Technique and Electronic Instruments for the EASA part 66 category B1.1.

I was glancing the syllabus for B1.1, I noted that the Basic Instrument is not included. To understand the Electronic Instruments, it is important to understand the basic instruments.

FAA provides a short note on the introduction to the topic. http://www.faa.gov/library/manuals/aviation/instrument_flying_handbook/media/FAA-H-8083-15A%20-%20Chapter%2003.pdf

The Topics Covered are:
A. The traditional Flight Instruments...
- Pitot Static Instrument - the ASI, altimeter and vertical speed.
- Compass -direct reading and remote reading compass
- gyroscope  instrument - the vacuum driven and electrical driven.
                                     - artificial horizon and the ADI


B. The paper also touches on the modern instruments and the glass cockpit.
- The PFD and Navigation Display.
- The GPWS and TCAS.

The paper is intended for pilot, but it is detail enough to give the understanding for maintenance staff. Moreover, understanding of how the instruments are used by pilot will give the aircraft engineer or mechanics a clearer understanding, as all these instruments have one thing in common, they are designed for pilots.

I find it odd that the Part 66 Modules for B1 Category of License exclude the topics of basic instrument. I consider the study of the following groups of instruments are necessary:
- pitot static instrument - covering altimeter, IAS and vertical speed indicator.
- gyro instruments - Artifical Horizon and HSI
- Compass - the direct and remote reading compass.  

Another site provides powepoint presentation which can be used for a class.
