APREQ for a block altitude with the next sector can be issued only after what condition is met?

APREQ for a block altitude with the next sector can be issued only after what condition is met?

• A. Immediately after handoff.
• B. Before handoff.
• C. Only after sector 66 has initiated a handoff.
• D. Never.

Answer: (C)

Coordinating a block altitude across adjacent sectors hinges on the receiving sector being prepared to take control of the aircraft. When you want to apply a block of altitude for an aircraft that will transition to the next sector, it’s essential that the next sector has begun the handoff process. This ensures the new sector is aware of the aircraft, has a visible data picture, and will enforce the altitude constraint as the aircraft enters its airspace. Issuing the APREQ only after the next sector has initiated handoff guarantees continuity of surveillance and responsibility, so the altitude block can be applied reliably during the transfer. If you try to issue it before any handoff activity starts, the receiving sector may not yet be aware of the aircraft or prepared to manage the constraint; issuing it after handoff has fully completed can still leave a timing gap in enforcement. Therefore, the required condition is that the next sector has started the handoff with the aircraft.
