  • 3-9-4. LINEUP AND WAIT (LUAW)

    1. The intent of LUAW is to position aircraft for an imminent departure. Authorize an aircraft to line up and wait, except as restricted in subpara g, when takeoff clearances cannot be issued because of traffic. Issue traffic information to any aircraft so authorized. Traffic information may be omitted when the traffic is another aircraft which has landed on or is taking off the runway and is clearly visible to the holding aircraft. Do not use conditional phrases such as “behind landing traffic” or “after the departing aircraft.”
    2. First state the runway number followed by the line up and wait clearance.
      • PHRASEOLOGY
      • RUNWAY (number), LINE UP AND WAIT.

      NOTE: When using LUAW, an imminent departure is one that will not be delayed beyond the time that is required to ensure a safe operation. An aircraft should not be in LUAW status for more than 90 seconds without additional instructions.

    3. Procedures.
      1. At facilities without a safety logic system or facilities with the safety logic system in the limited configuration:
        1. (a) Do not issue a landing clearance to an aircraft requesting a full-stop, touch-and-go, stop-and-go, option, or unrestricted low approach on the same runway with an aircraft that is holding in position or taxiing to line up and wait until the aircraft in position starts takeoff roll.
          • PHRASEOLOGY
          • RUNWAY (number), CONTINUE, TRAFFIC HOLDING IN POSITION,
          • or
          • RUNWAY (number) (pattern instructions as appropriate) TRAFFIC HOLDING IN POSITION.
          • EXAMPLE
          • “American 528, Runway Two Three continue, traffic holding in position.”
          • “Twin Cessna Four Four Golf, Runway One Niner Right, base approved, traffic holding in position.”
          • “Baron Two Five Foxtrot, Runway One Niner, extend downwind, tower will call your base, traffic holding in position.”
        2. (b) Do not authorize an aircraft to LUAW if an aircraft has been cleared to land, touch-and-go, stop-and-go, option, or unrestricted low approach on the same runway.
          • PHRASEOLOGY
          • RUNWAY (number), CONTINUE, TRAFFIC HOLDING IN POSITION.
          • EXAMPLE
          • “American 528, Runway Two-Three continue, traffic holding in position.”
      2. Except when reported weather conditions are less than ceiling 800 feet or visibility less than 2 miles, facilities using the safety logic system in the full core alert mode:
        1. (a) May issue a landing clearance for a full-stop, touch-and-go, stop-and-go, option, or unrestricted low approach to an arriving aircraft with an aircraft holding in position or taxiing to LUAW on the same runway, or
        2. (b) May authorize an aircraft to LUAW when an aircraft has been cleared for a full stop, touch-and-go, stop-and-go, option, or unrestricted low approach on the same runway.
    4. When an aircraft is authorized to line up and wait, inform it of the closest traffic within 6 flying miles requesting a full stop, touch-and-go, stop-and-go, option, or unrestricted low approach to the same runway.
      • EXAMPLE
      • “United Five, Runway One Eight, line up and wait. Traffic a Boeing Seven Thirty Seven, six mile final.”
    5. Do not authorize an aircraft to line up and wait when the departure point is not visible from the tower, unless the aircraft’s position can be verified by ASDE or the runway is used for departures only.
    6. An aircraft may be authorized to line up and wait at an intersection between sunset and sunrise under the following conditions:
      1. The procedure must be approved by the appropriate Service Area Director of Air Traffic Operations.
      2. The procedure must be contained in a facility directive.
      3. The runway must be used as a departure-only runway.
      4. Only one aircraft at a time is permitted to line up and wait on the same runway.
      5. Document on FAA Form 7230-4, Daily Record of Facility Operation, the following: “LUAW at INT of RWY (number) and TWY (name) IN EFFECT” when using runway as a departure-only runway. “LUAW at INT of RWY (number) and TWY (name) SUSPENDED” when runway is not used as a departure-only runway.
    7. Do not authorize an aircraft to line up and wait at anytime when the intersection is not visible from the tower.
    8. Do not authorize aircraft to simultaneously line up and wait on the same runway, between sunrise an sunset, unless the local assist/local monitor position is staffed.
    9. USN. Do not authorize aircraft to line up and wait simultaneously on intersecting runways.
      • PHRASEOLOGY
      • CONTINUE HOLDING, or
      • TAXI OFF THE RUNWAY.
    10. When aircraft are authorized to line up and wait on runways that intersect, traffic must be exchanged between that aircraft and the aircraft that is authorized to line up and wait, depart, or arrive to the intersecting runway(s).
      • EXAMPLE
      • “United Five, Runway Four, line up and wait, traffic holding Runway Three-One.”
      • “Delta One, Runway Three-One, line up and wait, traffic holding Runway Four.”
      • Or, when issuing traffic information to an arrival aircraft and an aircraft that is holding on runway(s) that intersect(s):

      • “Delta One, Runway Four, line up and wait, traffic landing Runway Three-One.”
      • “United Five, Runway Three-One, cleared to land. Traffic holding in position Runway Four.”
      • Or, when issuing traffic information to a departing aircraft and an aircraft that is holding on runway(s) that intersect(s):

      • “Delta One, Runway Three-One, line up and wait, traffic departing Runway Four.”
      • “United Five, Runway Four, cleared for takeoff, traffic holding in position Runway Three-One.”
    11. When a local controller delivers or amends an ATC clearance to an aircraft awaiting departure and that aircraft is holding short of a runway or is holding in position on a runway, an additional clearance must be issued to prevent the possibility of the aircraft inadvertently taxiing onto the runway and/or beginning takeoff roll. In such cases, append one of the following ATC instructions as appropriate:
      1. HOLD SHORT OF RUNWAY, or
      2. HOLD IN POSITION.
    12. USAF/USN. When issuing additional instructions or information to an aircraft holding in takeoff position, include instructions to continue holding or taxi off the runway, unless it is cleared for takeoff.
      • PHRASEOLOGY
      • CONTINUE HOLDING, or
      • TAXI OFF THE RUNWAY.
    13. When authorizing an aircraft to line up and wait at an intersection, state the runway intersection.
      • PHRASEOLOGY
      • RUNWAY (number) AT (taxiway designator), LINE UP AND WAIT.
    14. When two or more aircraft call the tower ready for departure, one or more at the full length of a runway and one or more at an intersection, state the location of the aircraft at the full length of the runway when authorizing that aircraft to line up and wait.
      • PHRASEOLOGY
      • RUNWAY (number), FULL-LENGTH, LINE UP AND WAIT.
      • EXAMPLE
      • “American Four Eighty Two, Runway Three-Zero full length, line up and wait.”

      NOTE: The controller need not state the location of the aircraft departing the full length of the runway if there are no aircraft holding for departure at an intersection for that same runway.

    15. Do not use the term “full length” when the runway length available for departure has been temporarily shortened. On permanently shortened runways, do not use the term “full length” until the Chart Supplement U.S. is updated to include the change(s).

      NOTE: The use of the term “full length” could be interpreted by the pilot(s) as the available runway length prior to the runway being shortened.

    16. Whenever a runway length has been temporarily or permanently shortened, state the word “shortened” immediately following the runway number as part of the line up and wait clearance.
      1. The addition of “shortened” must be included in the line up and wait clearance for the duration of the construction project when the runway is temporarily shortened.
      2. The addition of “shortened” must be included in the line up and wait clearance until the Chart Supplement U.S. is updated to include the change(s) when the runway is permanently shortened.
      • PHRASEOLOGY
      • RUNWAY (number) SHORTENED, LINE UP AND WAIT.
      • EXAMPLE
      • “Runway Two-Seven shortened, line up and wait.”
