Which action is prohibited to achieve separation?

• A. Move an aircraft into sector 45's airspace to achieve separation
• B. Reroute an aircraft completely out of sector 66's airspace to avoid traffic
• C. Both A and B
• D. None of the above

Answer: (C)

Maintaining safe separation relies on handling traffic within established sector boundaries and using coordinated, approved maneuvers rather than bypassing sector limits. Moving an aircraft into another sector’s airspace to achieve separation is not allowed because it takes control away from the sector responsible for that airspace, can disrupt the other sector’s traffic flow, and erodes mutual awareness and coordination. Rerouting an aircraft completely out of a sector to avoid traffic is also prohibited for the same reason: it removes the aircraft from the controller’s jurisdiction without proper clearance or coordination, creating potential gaps in surveillance and safety. The correct approach is to resolve separation using permitted methods within the sector (such as speed changes, altitude adjustments, and vectoring) or through coordinated handoffs and reroutes that involve the appropriate sectors.
