The controller has one more tool at his/her disposal when the intensity of the precipitation returns begin to overwhelm even the CP function. We can activate two other circuits which are called background video circuits and LOG FTC. LOG FTC stands for logarithmic fast time constant and an exact discussion of how these systems align radar returns to eliminate weather areas is way above my head. In terms of what a controller sees on the radar scope when these circuits are activated however, the results are dramatic. This circuitry electronically outlines me strongest edges of the areas of precipitation and reduces or eliminates returns from the areas inside those outlines. Here again, the radar simply does not depict the weaker of these returns and only the strongest passively reflected target, usually the reply from an aircraft, will be displayed on the controller's scope inside the area.
Answer the questions.
1. When does the controller have one more tool at his/ her disposal?
2. What can be activated?
3. What does LOG FTC stand for?
4. What is it function?
5. What doesn’t the radar depict?
6. What will be displayed on the controller’s scope?
