NAV1 FINALS QUIZ 3 (1242)

True bearings are measured clockwise from (a)   north.

A ship’s gyro compass shows a bearing of 045°. The true bearing of the object is 047°. What is the gyro error?

• 2° East

• 2° West

• 0°

• Cannot be determined

Which of the following actions minimizes the effects of ship’s rolling on a liquid ballistic compass?

• Increase speed

• Proper installation and maintenance

• Adjust damping system

• Use latitude compensator

(a)   north is used as a reference for navigation charts.

(a)   errors occur when a gyro compass does not align correctly with cardinal points.

During a rapid maneuver, the gyro compass shows an incorrect heading. This is likely due to:

• Tilt error

• Damping error

• Course and speed error

• Latitude error

What should be done if the gyro compass shows a consistent deviation from true north?

• Replace the compass

• Apply corrections using navigational charts

• Ignore the deviation

• Reset the magnetic compass

Latitude errors in a gyro compass occur due to the (a)   of the Earth.

What is the difference between true north and gyro compass north?

• True north accounts for magnetic variation, while gyro compass north does not

• True north varies with the ship’s position

• Gyro compass north points directly to the geographic North Pole

• True north is a fixed reference, while gyro compass north can vary slightly

In correcting a compass, (a)   is subtracted or added from the compass direction to obtain magnetic direction.
