Lesson notes

Learning Objectives

Indicator: 1.2.1.LI.3 - Explain the functions of surveillance systems.

By the end of the lesson, learners can:

Define surveillance systems in aviation and aerospace and state their primary purpose of tracking aircraft and spacecraft in real time.
Identify at least three types of aviation surveillance systems (Primary Surveillance Radar, Secondary Surveillance Radar, and Automatic Dependent Surveillance Broadcast) and describe how each works.
Explain the function of each surveillance system component, including ground radar stations, transponders, and satellite-based tracking.
Compare the functions of aviation surveillance systems with everyday surveillance tools such as CCTV cameras and telescopes, noting similarities and differences.
Justify why real-time location knowledge of aircraft is critical for safety, collision avoidance, and efficient air traffic management.

Exemplars (from the NaCCA curriculum)

Talk for Learning
- Initiate a question and answer session on what CCTV cameras are and how they are used for surveillance. Encourage learners to contribute in class as individuals and respect the views of others.
- In pairs or small mixed ability groups, learners identify surveillance objects/gadgets such as CCTV cameras and telescope. They should explain what they are and their use and present to the class
in turns. Guide presentation and organise their thought.
Experiential Learning: In pairs, let students monitor an event outside the classroom and give a report.
Teaching and Learning Resources:
- A catalogue of products from an avionics company, e.g.,
- Garmin * Books about avionics systems, e.g., Introduction to avionics (by R. P. G. Collinson), Aircraft Communication and Navigation
- Systems (by Mike Tooley and David Wyatt) * Two-way radios (two canned tins with thread/wire)
- Magnetic compasses
- Movies such as Dora the adventurer, pirates
- Satellite dish
- and cartoons about
