## EXAMPLE − 

1. Areas of precipitation (can be reduced by CP) 

2. Arrival/departure tabular list 

3. Trackball (control) position symbol (A) 

4. Airway (lines are sometimes deleted in part) 

5. Radar limit line for control 

6. Obstruction (video map) 

7. Primary radar returns of obstacles or terrain (can be removed by MTI) 

8. Satellite airports 

9. Runway centerlines (marks and spaces indicate miles) 

10. Primary airport with parallel runways 

11. Approach gates 

12. Tracked target (primary and beacon target) 

13. Control position symbol 

14. Untracked target select code (monitored) with Mode C readout of 5,000’ 

15. Untracked target without Mode C 

16. Primary target 

17. Beacon target only (secondary radar) (transponder) 

18. Primary and beacon target 

19. Leader line 

20. Altitude Mode C readout is 6,000’ (Note: readouts may not be displayed because of nonreceipt of beacon information, garbled beacon signals, and flight plan data which is displayed alternately with the altitude readout) 

21. Ground speed readout is 240 knots (Note: readouts may not be displayed because of a loss of beacon signal, a controller alert that a pilot was squawking emergency, radio failure, etc.) 

22. Aircraft ID 

23. Asterisk indicates a controller entry in Mode C block. In this case 5,000’ is entered and “05” would alternate with Mode C readout. 

24. Indicates heavy 

25. “Low ALT” flashes to indicate when an aircraft’s predicted descent places the aircraft in an unsafe proximity to terrain. 

(Note: this feature does not function if the aircraft is not squawking Mode C. When a helicopter or aircraft is known to be operating below the lower safe limit, the “low ALT” can be changed to “inhibit” and flashing ceases.) 

26. NAVAIDs 

27. Airways 

28. Primary target only 

29. Nonmonitored. No Mode C (an asterisk would indicate nonmonitored with Mode C) 

30. Beacon target only (secondary radar based on aircraft transponder) 

31. Tracked target (primary and beacon target) control position A 

32. Aircraft is squawking emergency Code 7700 and is nonmonitored, untracked, Mode C 

33. Controller assigned runway 36 right alternates with Mode C readout 

(Note: a three letter identifier could also indicate the arrival is at specific airport) 

34. Ident flashes 

35. Identing target blossoms 

36. Untracked target identing on a selected code 

37. Range marks (10 and 15 miles) (can be changed/offset) 

38. Aircraft controlled by center 

39. Targets in suspend status 

40. Coast/suspend list (aircraft holding, temporary loss of beacon/target, etc.) 

41. Radio failure (emergency information) 

42. Select beacon codes (being monitored) 

43. General information (ATIS, runway, approach in use) 

44. Altimeter setting 

45. Time 

46. System data area
