Electrical Fundamentals Level I course will provide a basic knowledge of the fundamentals of electricity and electrical engineering. The course contains such subjects as: Electron theory, static electricity and conduction, generation and sources of electricity. It also includes engineering mathematics, and power. In order to facilitate this, students will be engaged in a multitude of practical tasks which will reinforce the classroom based theory work. In addition, a variety of electrical laws are studied and applied to the various aircraft systems to calculate power, voltage, resistance and current. Furthermore, an aviation workshop is used to conduct most lessons. The workshop environment and equipment provides the opportunity and necessary foundation for students to become involved in authentic activities and equipment used in the aviation field. Assessment takes place ‘on the job’, or ‘off the job’ or can be a combination of both. Where assessment occurs off the job, an appropriate simulation is used where the range of conditions reflect realistic workplace situations. Competency will be demonstrated by students working either alone or as part of a team and the assessment environment helps to further reinforce the typical aviation workplace and is an ideal start to a career in aviation. The learner will be able to: • Discuss the sources of DC Voltage. • Recognize the Effects of an Electric Current and Resistance Technology • Investigate Kirchoff’s Current and voltage laws and perform resistance network measurements. • Recognize the very important effects and uses of magnetism and electromagnetism in electrical field. • Recognize the basic constructions and applications of a Capacitor • Discuss the types of lighting technologies used on aircraft.

This course adopts a step-by-step, project-based approach to teach students level 2 Java programming and concepts and skills for creating simple compute programs using java programming language. Java’s unique architecture enables programmers to develop a single application that can run across multiple platforms reliably seamlessly. In this hands-on course, students gain extensive experience with Java and its object-oriented features. Students will be able to explore and use classes, use methods and develop syntax to create windows components and change appearance of the components also Students learn to create robust console and GUI applications.

Students will enable students understand the creativity needed to program using basic programming skills using Hopscotch app. They will plan, design, code and test different computer games. Throughout the course, students will use a selected number of professional apps and a lot of hands on activities.

Notes Plus allows users to create annotations and type text easily and more accurately on their device. Better and more functional, Notes Plus features note-taking tools plus other features that users might want for all their note- taking needs. Notes Plus lets users create fine text notes simply by utilizing their fingers. Now, on to the review of my favorite features of Notes Plus: Below, I took a screenshot of the portrait layout of Notes Plus, imported the screenshot, and annotated it in Notes Plus to show the features and tools available. The layout is simple and intuitive, easily customizable. Please feel free to leave a review. Thank you Mr.N.T
