What are the difference between the radar control and procedure control1) radar- ground equipment; procedure- aircraft equipment(NDB,VOR),report mandatory reporting point, report level and time over the point.2) radar control is more precise and accurate than procedure control , and can provide smaller separation for aircrafts, thus increase the safety and efficiency for operation3) radarheight, speed, heading, SID, STAR,(actively)PROCEDUREpilots intention(passively )4) Radarholding at any random position in the controlled airspace. Procedureholding above NDB or VOR 5) RADAR- radar contact with the airplane on the radar screen, procedureimagine the position of the aircraft on the route9. What should the controller do in case of the ground collision.刮蹭1）report to the supervisor, ask for the emergency assistance, ambulance, passenger steps and ferry-buses, tow-car, 2）Contact pertinent department, arrange emergency avoidance for other aircrafts.3） To cooperate with the accident research team10. In case of radar failure , what should you do1）firstly, calm down, report the situation to the supervisor and terminate radar service2）when the radar failed, the back-up system will be used, and the radar control will be converted to procedure control, and the procedure separation will be applied3）instruct other planes to hold position if they are on the ground.11. what should the air-traffic controller do in the runway incursion2) Report the situation to the aircraft that will be taking-off or landing 3) To ask the maintenance personnel to execute the runway inspection 11. what should
