Question

What is TRUE of the history display of a target's past positions on an ARPA?

1) It shows the target's past positions in real-time
2) It shows the target's past positions in a graphical format
3) It shows the target's past positions using GPS coordinates
4) It shows the target's past positions using radar data

Answer 1

ARPA displays a target's past positions using a graphical format based on radar data, not in real-time or with GPS coordinates. so, option 2 and 3 are correct.

Step-by-step explanation:

The Automatic Radar Plotting Aid (ARPA) is used to track and display the history of a target's past positions. It is important to clarify what this technology relies on and the information it provides:

1. It shows the target's past positions in a graphical format.
2. It shows the target's past positions using radar data, not GPS coordinates.

ARPA systems do not show the target's positions in real-time; instead, they display a historical and graphical record of where the target has been based on radar contacts.

The history display of a target's past positions on an ARPA is shown in a graphical format, not in real-time. The display can use GPS coordinates or radar data.

The history display of a target's past positions on an ARPA is typically shown in a graphical format. It does not show the target's past positions in real-time. The display may utilize GPS coordinates or radar data, depending on the type of system being used.
