.2 The ATCO workload
On the figure 7.2 there is the ATCO workload coefficient for every 10 minutes. According to this diagram:
- Average ATCO workload=0.67;
- Min ATCO workload=0.090;
- Max ATCO workload=0.895.the analysis of results obtained above I can make the conclusion that the ATCO is overloaded because there is a period of time when the workload coefficient is greater than maximum acceptable. That s why I decided to divide CTA «Ivlieva» on two parts in horizontal plane to decrease the workload of a controller.

Thus, according to the obtained results we see that the ATCO workload fell down and remained acceptable during the all period.

.9.3 The ATCO workload in the CTA «Ivlieva_South»
We see that ATCO workload fell down and became normal during the all period of time.
Conclusion
After the performance of term work I analyzed obtained results and made the conclusion that the ATCO workload depends on such traffic indicators as density, intensity, etc. That s why suitable planning of airspace structure leads to declining of workload which reduces the possibility of conflicts and conflict situations appearance.
