Which phraseology is correct for a traffic call to non-radar identified aircraft?

The correct phraseology for a traffic call to non-radar identified aircraft must contain specific elements that facilitate clear communication between air traffic control and the pilots. In the provided choice, the phraseology includes necessary details like the call sign of the receiving aircraft, the position of the traffic in relation to a known point (MOTHER), the distance to the traffic (six miles), the direction in which the traffic is moving (southeast bound), the type of aircraft (F-18), and the altitude or flight level (ANGELS NINETEEN).

These elements ensure that the pilot has all the pertinent information needed to maintain situational awareness and make informed decisions regarding their flight path. The structure and clarity of this phraseology follow standard procedure and allow for easy comprehension during operations, especially when radar tracking is not available.

Each of the other options fails to adhere fully to the required format, contain necessary details, or provide clarity. For instance, discrepancies in directional references, the description of the aircraft type, or inadequate information about altitudes could lead to misunderstandings that compromise safety and effective navigation.
