3-9-4 Takeoff Position Hold

 a. Authorize an aircraft to taxi into position and hold, except as restricted in subparagraph e, when takeoff clearance 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 same runway and is clearly visible to the holding aircraft. Do not use conditional phrases such as "behind landing traffic" or "after the departing aircraft."

 b. USN NOT APPLICABLE. First state the runway number followed by the taxi into position clearance when more than one runway is active.

PHRASEOLOGY -
 RUNWAY (number), TAXI INTO POSITION AND HOLD.
or when only one runway is active:

 TAXI INTO POSITION AND HOLD.
 c. When an aircraft is authorized to taxi into takeoff position to hold, inform it of the closest traffic that is cleared to land, touch-and-go, stop-and-go, or unrestricted low approach on the same runway.

EXAMPLE -
 "United Five, runway one eight, taxi into position and hold. Traffic a Boeing seven thirty seven, six mile final."
or, when only one runway is active:
 "United Five, taxi into position and hold. Traffic a Boeing seven thirty seven, six mile final."
 d. USAF: When an aircraft is authorized to taxi into takeoff position to hold, inform it of the closest traffic within 6 miles on final approach to the same runway. If the approaching aircraft is on a different frequency, inform it of the aircraft taxiing into position.
 e. Do not authorize an aircraft to taxi into position and hold at an intersection between sunset and sunrise or at anytime when the intersection is not visible from the tower.
 f. USN: Do not authorize aircraft to taxi into takeoff position to hold simultaneously on intersecting runways.

PHRASEOLOGY -
CONTINUE HOLDING,
   or
TAXI OFF THE RUNWAY.

REFERENCE -
FAAO 7110.65, Altitude Restricted Low Approach, paragraph 3-10-10.
 g. 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 shall 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

 h. 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.
REFERENCE -
FAAO 7110.65, Altitude Restricted Low Approach, paragraph 3-10-10.

3-9-5 Anticipating Separation

 Takeoff clearance need not be withheld until prescribed separation exists if there is a reasonable assurance it will exist when the aircraft starts takeoff roll.

3-9-6 Same Runway Separation

 Separate a departing aircraft from a preceding departing or arriving aircraft using the same runway by ensuring that it does not begin takeoff roll until:

 a. The other aircraft has departed and crossed the runway end or turned to avert any conflict. If you can determine distances by reference to suitable landmarks, the other aircraft need only be airborne if the following minimum distance exists between aircraft: (See Figure 3-9-1 and Figure 3-9-2).

  1. When only Category I aircraft are involved - 3,000 feet.
  2. When a Category I aircraft is preceded by a Category II aircraft - 3,000 feet.
  3. When either the succeeding or both are Category II aircraft - 4,500 feet.
  4. When either is a Category III aircraft -  6,000 feet.
  5. When the succeeding aircraft is a helicopter, visual separation may be applied in lieu of using distance minima.

  2. An arrival follows a heavy jet/B757 departure.

{New-98-3 Revised February 26, 1998}

 h. Air traffic controllers shall not approve pilot requests to deviate from the required wake turbulence time interval if the preceding aircraft is a heavy jet/B757.
 i. Separate a small aircraft behind a large aircraft taking off or making a low/missed approach when utilizing opposite direction takeoffs on the same runway by 3 minutes unless a pilot has initiated a request to deviate from the 3-minute interval. In the latter case, issue a wake turbulence advisory before clearing the aircraft for takeoff.

NOTE -
1 - A request for takeoff does not initiate a waiver request.
2 - To initiate a waiver of the 3 minute rule, the request for takeoff must be accompanied by a request to deviate from the 3-minute rule.

Issue a wake turbulence cautionary advisory and the position of the large aircraft.

EXAMPLE -

"Caution wake turbulence, DC-9 on base leg."

{New-98-3 Revised February 26, 1998}

  4. Successive touch-and-go and stop-and-go operations are conducted with any aircraft following a heavy aircraft/B757 in the pattern, or heavy aircraft/B757 departing the same runway, provided the pilot of the aircraft is maintaining visual separation/spacing behind the preceding heavy aircraft/B757. Issue a wake turbulence cautionary advisory and the position of the heavy aircraft/B757.
