We must learn how to navigate the airplane. In order to do this, we must know the starting point, the distance to be traveled, and the direction to be traveled. This is know as “dead reckoning.”
A chart, pilots map, is used to set up the airways a pilot must follow to get to his destination. A compass rose is used to plot headings and the course line to be followed.

The distance to be traveled is figured mathematically by multiplication. Air speed times time traveled = distance traveled.
We can introduce the formula distance = velocity times time and have some fun determining different factors of a flight. We use the term velocity instead of speed as we must know the direction we are traveling as well as the speed when we are dealing with navigation.
If you have access to the Science Toolkit-Speed and Motion, this will allow the student to do actual measurements with a balloon car.
Let us now look at how aviation influences our environment.
