What are the standard communications channels for coordinating with on-scene assets?

• A. No radio use; only signal flags.
• B. AM broadcast channels from land stations.
• C. Satellite data link with on-scene assets.
• D. VHF Channel 16 for hails and distress, plus a designated working channel (for example Channel 22A) for routine coordination.

Answer: (D)

The standard approach to coordinating with on-scene assets relies on two-step radio use: first establish contact on the hailing channel, then move to a designated working channel for routine coordination. Channel 16 is the internationally recognized hailing and distress channel, kept monitored for emergencies and used to initiate contact. Once contact is made, both parties switch to a designated working channel (for example Channel 22A) to handle routine coordination—sharing positions, intentions, updates, tasks, and any hazards. This keeps Channel 16 open for emergencies and ensures clear, efficient communication among all on-scene assets. Other methods may exist, but they don’t provide the same widely understood, immediate contact workflow for coordinating operations.
