NAV3 MID QUIZ 3 (1373)

What is the primary purpose of the running fix method in navigation?

• To estimate distance to an object

• To determine the ship's position using multiple bearings

• To identify landmarks on a map

• To calculate the speed of the ship

When is the running fix method most useful?

• When navigating in open water

• When GPS systems are unreliable or unavailable

• During extreme weather conditions

• While docking a ship

Which factor can affect the accuracy of the running fix?

• Time of day

• Distance to the fixed object

• Speed of the vessel

• Errors in taking compass bearings

What does L.O.P stand for in navigation?

• Line of Plotting

• Length of Position

• Line of Position

• Latitude of Position

What is the first step in plotting a running fix?

• Plot the dead reckoning position

• Take a second bearing

• Plot the initial position and course

• Calculate the speed of the vessel

What does the term "dipping range" refer to in navigation?

• The distance a light can be seen from below the horizon

• The maximum visibility of an object

• The horizontal range of a lighthouse

• The depth of the sea

What is the geographical range of a light source?

• The maximum distance at which a light can be seen under ideal conditions

• The distance limited by the Earth's curvature

• The range depending on atmospheric conditions

• The height of the observer above sea level

Which statement is true about the luminous range?

• It depends solely on the height of the observer

• It is always equal to the geographical range

• It considers both light intensity and prevailing weather conditions

• It can only be determined using electronic equipment

What is the significance of the Bow and Beam Bearing Method?

• It is used to find a ship's speed

• It helps in determining the ship's position using two bearings of the same object

• It estimates the geographical range of a light source

• It is only used in open sea navigation

What is the first step in the Bow and Beam Bearing Method?

• Taking the bearing when the object is near the ship's bow

• Taking the bearing when the object is at the beam

• Plotting the ship's speed

• Identifying a fixed object
