What code indicates arriving to Fillstand?

• A. 10-4: Acknowledged; will comply
• B. 10-10: Return to FSC
• C. 10-97: Arrived at scene/location
• D. 10-14: Arriving to Fillstand

Answer: (D)

Understanding radio status codes, the message you send isn’t about simply saying you heard someone; it conveys your current status and next action. Acknowledgement is just that you received the instruction, not where you are. A code about returning to the field command center tells others you’re headed back, not arriving at a location. A code that means you’ve already reached the scene lets everyone know you’re on-site. The status that indicates you are in the process of getting to the location—en route and about to arrive—provides the key real-time update others need to prep for your arrival. That makes it the best fit for signaling you’re on the way to Fillstand, hence why that option is correct.
