This lesson explores the fascinating world of avionics navigation systems. Just as our forefathers used the stars, rivers, and unique trees like the giant *odum* tree to find their way, and how we use Google Maps on our phones to navigate through Accra or Kumasi today, pilots use advanced electronic systems to guide their aircraft safely across vast distances. Understanding these systems is fundamental to appreciating how modern aviation achieves its incredible safety and efficiency. We will learn how aircraft know where they are, where they are going, and the best way to get there, whether flying from Tamale to Accra or across the mighty Atlantic Ocean.
Starter Activity (Engage Phase - 10 mins) Teacher: "Class, imagine you have hidden your favourite snack somewhere in the school compound and you want to give your friend a clue to find it. What kind of instructions would you give?" *(Elicit responses like: "Start from the classroom door, take 20 steps towards the big mango tree, then turn right and walk 10 steps.")* Teacher: "Excellent. Now, think about our grandparents. How did they travel from one village to another without a map or a phone? How did they find their way back home from the farm?" *(Guide a discussion about using landmarks like rivers, hills, the position of the sun, and stars. This connects to the NaCCA exemplar on historical tracking methods.)* Teacher: "These are all forms of navigation. Today, we will learn about the high-tech electronic systems that pilots use for the same purpose: to navigate an aircraft." Core Content Explanation
A. What is Avionics and Navigation? Avionics: This is a simple combination of two words: Aviation and Electronics. Avionics refers to all the electronic systems used on an aircraft, including communication, control, and display systems. Navigation: This is the process of planning, recording, and controlling the movement of a craft or vehicle from one place to another.
Therefore, an Avionics Navigation System is an electronic system onboard an aircraft that helps the pilot determine the aircraft's position and guide it along a planned route.
