What is the effect of sense of errors on ARPA equipment?
- They have no effect
- They can lead to inaccurate tracking
- They improve performance
- They only affect visual display
They can lead to inaccurate tracking
What should be done if the ARPA system indicates a malfunction?
- Continue using it without chart? changes
- Ignore the warning
- Follow the self-diagnostic routine
- Turn off the system
Follow the self-diagnostic routine
What is the significance of the time to CPA?
- It indicates the time until the next waypoint.
- It shows how long until the closest point of approach.
- It measures the time until the vessel reaches a critical area.
- It indicates the time until the radar will sound a dangerous target
It shows how long until the closest point of approach.
What is the primary function of the self-diagnostic routine in ARPA?
- Enhance radar range
- Monitor correct operation of circuits
- Provide weather updates
- To calculate collision data
Monitor correct operation of circuits

Inaccurate target positioning
What is the purpose of the trial maneuver in radar operation?
- To test the radar capabilities in maneuvering
- To assess the performance of the ARPA system
- To measure the speed of the vessel
- To determine the potential target in collision
To determine the potential target in collision
What should be done if a target is lost due? to poor radar return?
- Change the radar setting
- Continue searching for the target
- Ignore the target
- Change range setting
Change the radar setting
What is the main risk associated with over-reliance on ARPA?
- Increase accuracy
- Enhance navigational safety
- Reduce need for visual lookout
- Improve radar performance
Reduce need for visual lookout
Which of the following describes the characteristics of a good radar conspicuous object?
- To produce a poor response that is difficult to identify
- They’re visually obscured by par? but can be detected by radar
- They produce a good response that can be positively identified
- They are typically relied upon on moving target
They produce a good response that can be positively identified
What could be the effect of incorrect speed setting on true motion display?
- Improve target detection
- Accurate course prediction
- Misleading display tracks
- Enhance radar performance
Misleading display tracks
When assessing the performance of a radar system, which factor is crucial to ensure accurate reading?
- The color of the display
- The position of the operational controls
- The type of radar used
- The weather condition
The position of the operational controls/The weather condition
What is the purpose of the performance monitor in a radar system?
- To display any record changes
- To record data and monification?
- To adjust the radar’s brightness
- To change the presentation mode
To record data and monification?
How does 0 speed control function in a radar system?
- It stops the movement of the own ship on the PPI
- It percepts? the radar display
- It adjusts the speed input
- It changes the presentation mode
It stops the movement of the own ship on the PPI
When interpreting the track rate over the ground (speed over ground) by own ship, why is it important to distinguish between course made good and track made good?
- To ensure accurate navigation
- To simplify radar operation
- To reduce the workload of the operator
- To comply with the standard performance
To ensure accurate navigation
What does the term ‘maladjustment’ refer to in radar operation?
- Correct setting of control
- Poor or faulty? adjustments
- Bad optimum? performance level
- Not properly maintain
