Same Direction

When transitioning from an offshore airspace area to oceanic airspace or while within oceanic airspace, apply 5 minutes minimum separation when a following aircraft on the same course is climbing through the altitude of the preceding aircraft if the following conditions are met:

1. The preceding aircraft is level at the assigned altitude and is maintaining a speed equal to or greater than the following aircraft; and
2. The minimum of 5 minutes is maintained between the preceding and following aircraft; and
3. The following aircraft is separated by not more than 4,000 feet from the preceding aircraft when the climb clearance is issued; and
4. The following aircraft commences climb within 10 minutes after passing:
   1. An exact reporting point (DME fix or intersection formed from NAVAIDs) which the preceding aircraft has reported; or
   2. A radar observed position over which the preceding aircraft has been observed; and
5. The following aircraft is in direct communication with air traffic control until vertical separation is established. (See FIG 8-5-3.)
