6. Lateral Established routes: Protected airspace must not overlap. Fixes: Holding airspace must not overlap. Departures: Courses must diverge by at least 45 degrees.

7. Primary Radar Basic principle of radar operation is based on time needed for transmitted electrical pulses moving at the speed of light to reach a target and return.

8. Primary Radar The radar display uses a sweep signal on the scope which moved outward from the center at a scaled rate.

9. Primary Radar Echo pulses are fed to the scope as a blip at the correct scale distance. Azimuth information is provided by rotating the antenna through 360 degrees.

10. Radar -types and uses Air Route Surveillance Radar (ARSR): Used by ARTCC for traffic control. Range is up to 200 NM.

11. Radar -types and uses Airport Surveillance Radar (ASR): Used by approach control. Range is up to 60 NM.

12. Radar -types and uses Precision Approach Radar (PAR): Used for GCA. Range is about 10 NM.

13. Radar -limitations Ground clutter: Ground features return echoes causing clutter on the scope.

14. Radar -limitations Weather: Precipitation will return echoes making it difficult to see aircraft targets.

15. Secondary Radar Secondary radar transmits electronic pulses from a second antenna called an interrogator. And the aircraft transponder responds to interrogation pulses with coded pulses of new energy.

16. Secondary Radar This increases the radar�s range and and provides for easily identified targets.

31. Radar Vectors for Instrument Approach Procedures

32. Approach Gate An imaginary point used within ATC as a basis for vectoring aircraft to the final approach course.

33. Approach Gate The gate will be established along the final approach course 1 mile from the outer marker (or the fix used ILO the outer marker) on the side away from the airport for precision approaches and 1 mile from the final approach fix on the side away from the airport for nonprecision approaches.

34. Approach Gate In either case when measured along the final approach course, the gate will be no closer than 5 miles from the landing threshold.

36. 5-9-1 Vectors to Final Approach Course Except as provided in paragraph 7-4-2, vector arriving aircraft to intercept the final approach course:

37. 5-9-1 Vectors to Final Approach Course a. At least 2 miles outside the approach gate unless one of the following exists:

38. 5-9-1 Vectors to Final Approach Course 1. When the reported ceiling is at least 500 feet above the MVA/MIA and the visibility is at least 3 miles, aircraft may be vectored to intercept the final approach course closer than 2 miles outside the approach gate but no closer than the approach gate.

39. 5-9-1 Vectors to Final Approach Course 2. If specifically requested by the pilot, aircraft may be vectored to intercept the final approach course inside the approach gate but no closer than the final approach fix.

40. 5-9-1 Vectors to Final Approach Course b. For a precision approach, at an altitude not above the glideslope/ glidepath or below the minimum glideslope intercept altitude specified on the approach procedure chart.

41. 5-9-1 Vectors to Final Approach Course c. For a nonprecision approach, at an altitude which will allow descent in accordance with the published procedure.

42. IFE Responsibility If your pilot is �under the hood� (simulated IMC) when the weather is beautiful, it is your job to insure that (s)he gets IMC treatment from ATC.

43. Controller Responsibility Issue: Position relative to fix. Vector to intercept. Altitude restriction (if needed). Approach clearance. Communications transfer (if needed).

44. Pilot Responsibility On radar vector maintain last assigned altitude until established on a published route or segment of the IAP.

45. 5-9-3 Vectors Across Final Approach Course Inform the aircraft whenever a vector will take it across the final approach course and state the reason for such action.

46. 5-9-3 Vectors Across Final Approach Course Note - In the event you are unable to so inform the aircraft, the pilot is not expected to turn inbound on the final approach course unless approach clearance has been issued.

47. 5-9-3 Vectors Across Final Approach Course Example - �Expect vectors across final for spacing.�
