    Issue by radio or directional light signals specific instructions which approve or disapprove the movement of aircraft, vehicles, equipment, or personnel on the movement area except where permitted in an LOA.

    • FAA Order JO 7210.3, Para 4-3-1, Letters of Agreement
    • FAA Order JO 7210.3, Para 4-3-2, Appropriate Subjects
    1. Do not issue conditional instructions that are dependent upon the movement of an arrival aircraft on or approaching the runway or a departure aircraft established on a takeoff roll. Do not say, “Line up and wait behind landing traffic,” or “Taxi/proceed across Runway Three-Six behind departing/landing Citation.” The above requirements do not preclude issuing instructions to follow an aircraft observed to be operating on the movement area in accordance with an ATC clearance/instruction and in such a manner that the instructions to follow are not ambiguous.
    2. Do not issue unconditional instructions when authorizing movement on a runway/taxiway for the purpose of airfield checks or other airport operations. Instructions must ensure positive control with specific instructions to proceed on a runway or movement area, and as necessary, hold short instructions.
      • EXAMPLE
      • “Airport 1, proceed on Runway 26R, hold short of Runway 18L.”
      • “Airport 1 proceed on taxi way B, hold short of Runway18L.”
      • “Airport 1 proceed on Runway 26R.” (additional instructions as necessary.)
      • NOTE:
      • 1. The following are examples of unconditional instructions and are not approved for use: “THE FIELD IS YOURS,” “CLEARED ON ALL SURFACES,” “THE AIRPORT IS YOURS,” and “PROCEED ON ALL RUNWAYS AND TAXIWAYS.”
      • 2. “PROCEED AS REQUESTED” is not approved phraseology for instructing aircraft, vehicles, equipment, or personnel to cross or operate on a runway.
    3. Do not use the word “cleared” in conjunction with authorization for aircraft to taxi or equipment/vehicle/personnel operations. Use the prefix “taxi,” “proceed,” or “hold,” as appropriate, for aircraft instructions and “proceed” or “hold” for equipment/vehicles/personnel.
    4. Intersection departures may be initiated by a controller or a controller may authorize an intersection departure if a pilot requests. Issue the measured distance from the intersection to the runway end rounded “down” to the nearest 50 feet to any pilot who requests and to all military aircraft, unless use of the intersection is covered in appropriate directives.
      • NOTE:
      • 1. Exceptions are authorized where specific military aircraft routinely make intersection takeoffs and procedures are defined in appropriate directives. The authority exercising operational control of such aircraft ensures that all pilots are thoroughly familiar with these procedures, including the usable runway length from the applicable intersection.
      • 2. Some airports publish “declared distances” for a particular runway. These are published in the Chart Supplement U.S. or the Aeronautical Information Publication (AIP) and there is no requirement that facility personnel be aware of them. These distances are a means of satisfying airport design criteria and are intended to be used by pilots and/or operators for preflight performance planning only. There are no special markings, signing, or lighting associated with declared distances and they do not limit the actual runway available for use by an aircraft. Therefore, they cannot be used for any air traffic control purpose. If pilots inquire about the existence of declared distances, refer them to the Chart Supplement U.S. or AIP.
      • RUNWAY (number) AT (taxiway designator) INTERSECTION DEPARTURE (remaining length) FEET AVAILABLE.
    5. Do not use the term “full length” when the runway length available for departures 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).
      • FAA Order JO 7210.3, Para 10-3-12, Airport Construction.
      • FAA Order JO 7210.3, Para 10-3-13, Change in Runway Length Due to Construction.
