Ground lesson 19 (7) - Air Traffic Control services

Air traffic control system



  • Air Route Traffic Control Center (ARTCC)
    • Link between departure/ destination and the enroute structure
    • Service includes
      • ATIS
      • Clearance delivery
        • Reduce congestion on ground frequency

      • Control tower
        • Responsible for runway protected area and traffic separation
        • Ground is responsible for movement on the ground in the movement area

      • Approach and departure control 
        • Coordinates close with ARTCC to transition aircraft's between the terminal areas

      • ARTCC - air traffic control center
        • Provides nationwide monitoring of each IFR flight 
        • Also provides 
          • weather service 
          • traffic separation
          • emergency assistance

        • ARTCC traffic separation 
          • Provided for all IFR traffic except for vfr or VFR condition clearance
          • 3 NM within 40 NM of the radar antenna
          • 5 NM beyond 40 NM of the radar antenna

  • FSS - flight service station 
    • To obtain IFR clearance at non-towered airports and out of reach of clearance delivery 
    • Processing the IFR flight plan
      • “Center” computer scans your flight plan for preferred routes 
      • ATC then analyzes the route for possible restrictions (inop navaids)
      • When route is finalized it is sent out to all centers you may fly through

    • This is why you should file at least 30 minutes before departure

  • Radar service for VFR aircraft's 
    • Service is not mandatory but is recommended 
    • Provides safety alerts, traffic advisory and limited vectoring
    • Does not relieve you from obstacle clearance
