Diverging requirements
- tracks diverge by 15 degrees or more continuously until oceanic lateral separation is achieved
- established on radar
- transitioning from radar to oceanic
- radar separation exists at boundary

When can you not use the leaving report of an altitude to assign that altitude to another aircraft?
- Severe turbulence reported
- Military aerial refueling
- Previous aircraft was issued pilot’s discretion climb/descent
- Previous aircraft was issued a cruise clearance
