Write the correct solution of the following question
Question- Is it possible to briefly summarize how a commercial plane navigation system operates to a layperson (e.g. a passenger)? The aircraft takes off, reaches a certain altitude, and then lands perfect on a runway somewhere else.
Part 1- How does the navigation system affect this?
Part 2- How do pilots know where to go and where to land?
I need experts assist to explain the navigation system.
