Section 8. Spacing and Sequencing

3-8-1. SEQUENCE/SPACING APPLICATION

Establish the sequence of arriving and departing aircraft by requiring them to adjust flight or ground operation, as necessary, to achieve proper spacing.

3-8-2. TOUCH‐AND‐GO OR STOP‐AND‐GO OR LOW APPROACH

Consider an aircraft cleared for touch‐and‐go, stop‐and‐go, or low approach as an arriving aircraft until it touches down (for touch‐and‐go), or makes a complete stop (for stop‐and‐go), or crosses the landing threshold (for low approach), and thereafter as a departing aircraft.

3-8-3. SIMULTANEOUS SAME DIRECTION OPERATION

Authorize simultaneous, same direction operations on parallel runways, on parallel landing strips, or on a runway and a parallel landing strip only when the following conditions are met:

  1. Operations are conducted in VFR conditions unless visual separation is applied.
  2. Two‐way radio communication is maintained with the aircraft involved and pertinent traffic information is issued.
  3. The distance between the parallel runways or landing strips is in accordance with those specified in TBL 3-8-1.

3-8-4. SIMULTANEOUS OPPOSITE DIRECTION OPERATION

Authorize simultaneous opposite direction operations on parallel runways, on parallel landing strips, or on a runway and a parallel landing strip only when the following conditions are met:

  1. Operations are conducted in VFR conditions.
  2. Two‐way radio communication is maintained with the aircraft involved and pertinent traffic information is issued.
  3. The distance between the runways or landing strips is in accordance with the minima in TBL 3-8-2.
