When is an emergency strip deadwood?

• A. An emergency strip is deadwood after the aircraft lands.
• B. An emergency strip is deadwood when the EDST readout shows red.
• C. An emergency strip is deadwood only during emergencies.
• D. An emergency strip is deadwood when all coordination, stripmarking and supervisory notification are accomplished and frequency change issued to the next sector or facility.

Answer: (D)

Deadwood status for an emergency strip is reached when all required wrap-up actions have been completed and the handoff to the next sector or facility is in place. This means coordinating with the affected sectors, making the strip markings to indicate the emergency, notifying supervision, and issuing the frequency change so the next controller takes over. Only after these steps are finished is the strip no longer active and moved to deadwood, preventing confusion and ensuring a clean transfer of responsibility. The other options don’t fit because deactivation isn’t triggered simply by aircraft landing, by an EDST readout color, or by being applicable only during emergencies; it follows the formal completion of coordination, handoff, and frequency change.
