SHS3 Aviation And Aerospace Engineering · Semester 1 Week 19: Communication, Navigation and Surveillance Systems

Lesson notes

Learning Objectives

Indicator: 3.2.3.LI.2 - Identify the advantages and disadvantages of the different navigation technologies.

By the end of the lesson, learners can:

Compare at least four different navigation technologies used in aircraft and spacecraft, stating one advantage and one disadvantage of each.
Justify the choice of a specific navigation technology for a given flight scenario, using at least two reasons based on its advantages and limitations.
Evaluate the reliability of a handheld compass, navigation charts, GPS, and inertial navigation systems by ranking them for accuracy in different conditions.
Work collaboratively in mixed-gender, mixed-ability groups to present a balanced view of one navigation technology, respecting diverse opinions during group discussions.
Apply strategic reasoning to determine which navigation technology (or combination) is most suitable for a long-haul flight from Accra to London versus a short domestic flight from Accra to Kumasi.
