What is the operational area defined for GMDSS Area A2?

The operational area defined for GMDSS (Global Maritime Distress and Safety System) Area A2 is indeed 100-150 nautical miles from shore-based VHF stations. This region is specifically identified as the area where vessels can rely on VHF radio capabilities, which are critical for communication and distress signaling.

VHF radio operates primarily within line-of-sight and is effective for short-range communications. The A2 area is strategically defined to provide adequate coverage that allows vessels operating in this zone access to reliable VHF communication with coastal stations. This is particularly important for safety at sea, as it enables timely assistance and coordination during emergencies.

The other defined areas, like A1, cover shorter ranges, while A3 and A4 cover broader distances or regions, such as satellite communications or more remote areas, demonstrating that communication capabilities and technologies vary significantly across different maritime zones. The specific delineation of the A2 area emphasizes the importance of VHF radio within its operational range for effective maritime safety management.
