2. Airspace
   1. Ground: All movement areas except 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.
5. Arrivals

Local

1. Frequency
   1. Twin Falls Tower: 118.200.
2. Airspace
   1. Local: Runway 8/26, 12/30, and airspace as depicted on sector file.
3. Procedures
   1. Runway operations
      1. Use runway 26 (West) during calm wind operations.
      2. Use runway 8 (East) when the tailwind component exceeds 5 knots.
   2. LAHSO
      1. Operations involving the simultaneous arrival or departure of aircraft on intersecting runways must be conducted in accordance with procedures contained in the FAA Orders JO 7100.65 and JO 7110.118.
         1. Land and Hold Short Operations (LAHSO) must only be conducted during daylight hours on dry runways.
         2. Aircraft landing on Runway 08 and instructed to hold short of Runway 12/30 has an available landing distance of 4,500′.
         3. Aircraft landing on Runway 12 and instructed to hold short of Runway 26/08 has an available landing distance of 2,750′.
         4. Aircraft landing on Runway 26 and instructed to hold short of Runway 12/30 has an available landing distance of 3,600′.
   3. Tower Use of Radar:
      1. None
4. Departures
   1. Departure Notification / Releases
      1. A “Release Request” (.RR) is required to be sent to the appropriate Departure Controller for all departing aircraft in accordance with the General Control Directive.
5. Arrivals
   1. IFR Arrivals
      1. N/A
   2. Missed Approach / Go Around
      1. 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.
      2. 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.
      3. The following is considered Primary Climb-Out procedure and does not require any special coordination with Approach Control or Strip marking other than the basic Missed Notification. Aircraft must not turn prior to the departure end of the runway. Comm-Change to the appropriate departure sector must be completed no later than 1 mile off the departure end of the runway.
      4. PRIMARY CLIMB OUT PROCEDURE:
         • East Flow: Left Heading 255, Maintain 8,000.
         • West Flow: Heading 255, Maintain 8,000.
      5. VFR traffic join local pattern.
6. VFR Operations
   1. VFR Departures
      1. Depart on-course.
      2. Handoff to departure control as soon as clear of any possible conflicts.
         • Twin Falls Approach 126.7
   2. VFR Arrivals
      1. Direct to airport.
   3. VFR Flight Following
      1. Ensure all aircraft requiring flight following have the appropriate scratchpad entry prior to handoff to departure.
