Hurrah, we come to the end of the module! In this module, we have seen how to graphically represent different quantities. We began the module asking how ATCs handle many different aeroplanes.

All ATCs have huge screens that have graphs similar to what we have seen in this module. It is much easier to understand data when you see it visually, than when you read the numbers.

Though working at the ATC is a very stressful job, having all the information shown visually using graphs makes the job much easier!
