If there is a possibility of confusion, which signal should be used to send the group "True Bearing 045 Degrees"?

The signal "A045" utilizes the established convention for conveying true bearings in maritime communication. In this context, the letter "A" specifically indicates an angular direction as it relates to navigational practices. The format typically involves a letter followed by a numerical degree. This method avoids potential misinterpretation, especially in scenarios where multiple signals could be similar in nature.

Using "A045" clearly denotes the intention to communicate the true bearing as 045 degrees without confusion, ensuring that all parties involved understand that it pertains to navigational direction. Other options that start with different letters might not be standard convention for communicating true bearing and could lead to ambiguity in navigation or communication, especially where precision is crucial. Therefore, the choice of "A045" aligns with established communication practices in maritime navigation.
