  1. Question 1

    Comparing manual and automatic acquisition, which is most sensitive?
    • Manual acquisition.
    • Automatic acquisition.
    • Same sensitivity.
    • Not relevant.
  2. Question 2

    Does current and drift affect the CPA/TCPA calculations on a true motion, true vector presentation?
    • No.
    • Yes.
    • Only a little bit.
    • Yes, very seriously.
  3. Question 3

    Does incorrect speed input affect the true vectors on a ARPA display?
    • No.
    • Yes.
    • Only a little bit.
    • Only if the input is speed over ground.
  4. Question 4

    How can the true course and speed of a target be found when the display is showing relative vectors?
    • By looking at the digital readout of target information.
    • By comparing target vector with own ships vector.
    • Can only be found by changing to true vectors.
    • By examining the vectors displayed.
  5. Question 5

    How can true vectors be easily identified as the vectors on display?
    • Own ship has a vector.
    • Own ship has no vector.
    • CPA and TCPA limits are broken and alarm is activated.
    • The vectors are the same direction as history dots.
