  2. Procedures
    1. When appropriate, inform pilots of the current ATIS information prior to contacting ground control.
  3. IFR Routing
    1. Initial Altitude: 15,000.

    3. All Operations
      1. Issue the BIL SID for all departures.
    4. If a pilot cannot accept a departure procedure, issue the following headings for radar vectors to their route, per their departure runway:
      • Runway 28L/R, 25 – Heading 280
      • Runway 10L/R, 7 – Heading 100
  4. Standard Departure Frequencies
    1. When appropriate, issue the following frequencies to IFR aircraft:
      • Billings 119.2
    2. When appropriate, issue the following frequencies to VFR aircraft requiring radar services after departure:
      • Billings 119.2
  5. VFR Routing
    1. All departures shall be instructed to maintain VFR at or below 7,500.


  1. Frequency
    1. Billings Ground: 121.900
  2. Airspace
    1. All movement areas with the exception of active runways.
  3. Procedures
    1. Not applicable.
  4. Departures
    1. All aircraft requiring pushback onto the movement area will contact ground prior to pushback and start-up.
    2. All aircraft will contact ground with position and ATIS prior to being issued taxi instructions.-
    3. During periods of high volumes of traffic, the published Standard Runway Assignments may be used to expedite the flow of departures.
    4. Standard Runway Assignments
      1. East Operations
        1. Runway 10L: IFR Operations
        2. Runway 10R: VFR Operations
      2. West Operations
        1. Runway 28R: IFR Operations
        2. Runway 28L: VFR Operations
  5. Arrivals
    1. All aircraft will remain on ground frequency until off the movement area.


  1. Frequency
    1. Billings Tower (Local): 127.200
  2. Airspace
    1. Local: Runways 10L/R, 28L/R, 7/25 and airspace as depicted on sector file.
  3. Procedures
    1. Runway operations
      1. Use runway 28R for arrivals (West) during calm wind operations.
      2. Use runway 10L (East) when the tailwind component exceeds 5 knots.
      3. All aircraft that require to overfly the field will be instructed to maintain 7,500.
    2. LAHSO
      1. Not authorized.
    3. Tower Use of Radar
      1. Full
  4. Departures
    1. Departure Notification / Releases
      1. Departure Notifications are not required, unless otherwise coordinated by TRACON.
      2. Departures are automatically released, unless otherwise coordinated by TRACON.
    2. IFR Departures
      1. Ensure aircraft turn to assigned point/heading and altitude reporting is operating prior to handoff to departure.
  5. Arrivals
    1. IFR Arrivals
      1. Accept radar handoff of all IFR arrivals, if radar certified and it is operationally beneficial.
    2. Missed Approach / Go Around
      1. Acquire the track control for the aircraft conducting a missed approach.
      2. Send A Missed Notification (.MA) for the aircraft executing an unplanned Missed Approach / Go Around to the appropriate TRACON sector that will be receiving the aircraft for re-sequencing.
      3. VFR aircraft, and/or IFR Category I / II aircraft conducting a Visual approach and executing a Go-Around must be instructed to remain in the local pattern, if capable of doing so.
      4. The following is considered Primary Climb-Out procedure and does not require any special coordination with Approach Control or Strip marking (Scratchpad entries) other than the basic Missed Notification. Aircraft must not turn prior to the departure end of the runway. Handoff/Comm-Change to the appropriate TRACON sector must be completed no later than 1 mile off the departure end of the runway.
        • East Flow: Heading 100, Maintain 7,000.
        • West Flow: Heading 280, Maintain 7,000.
  6. VFR Operations
    1. VFR Departures
      1. Depart on-course at or below 7,500′
      2. Handoff to departure control as soon as clear of any possible conflicts.
        • 119.2 (West of BIL)
        • 120.5 (East of BIL)
    2. VFR Arrivals
      1. Direct to airport at or below 7,500′.
    3. VFR Flight Following
      1. Ensure all aircraft requiring flight following have the appropriate scratchpad entry prior to handoff to departure.
