Which call format is used when addressing multiple aircraft?

The multiple station call format is specifically designed for situations where information needs to be conveyed to more than one aircraft at the same time. This format allows a controller or a pilot to address several aircraft simultaneously, ensuring that all parties receive important information efficiently and effectively.

In air traffic control, this form of communication is crucial when there is a need to alert multiple aircraft about changes in airspace, weather conditions, or operational instructions that may affect them all. Utilizing the multiple station call format helps to save time and optimizes communication, particularly in high-traffic situations.

The general call, while it may seem similar, is more vague and is not typically used for addressing specific groups; it may not be the most efficient way to communicate critical information to multiple aircraft. A single station call, as the name implies, targets only one aircraft at a time, which does not fit the requirement of addressing multiple aircraft. The pan-pan call, on the other hand, is intended for urgency but is still specific to a particular aircraft or situation rather than addressing a group.

Therefore, the multiple station call is the most appropriate choice for effectively communicating with multiple aircraft simultaneously.
