What are compass rules?
The compass rule may be stated as follows: the correction to be applied to the latitude or departure of any course is equal to the total closure of latitude or departure , multiplied by the ratio of the length of the course to the total length or perimeter of the traverse.
How do you use a compass at home?
Stand in the formal front door of your home facing out the door. Hold the compass flat, so it’s parallel to the floor, pointing out the front door. Determine what direction you are facing and write down the direction and degrees. Step back further into the home and take a few more readings.
How do I use a compass to navigate?
Hold the compass horizontally in front of you with the direction of travel arrow pointing away from you. Use this arrow to guide you to your destination. Turn your body until the north end of the magnetic needle is aligned with the orienting needle, and you’ll be properly oriented toward the destination on the map.
What is the correction for local attraction?
ADVERTISEMENTS: (ii) The observed bearings are corrected by applying correction to the stations affected by the local attraction. For this, error at each of the station is found and then starting from an unaffected bearing, the bearings of the successive lines are adjusted by applying corrections to them.
What makes a compass always point north?
The north pole of a compass magnet points toward the north. Earth’s south magnetic pole is near Earth’s geographic north. Earth’s magnetic north pole is near Earth’s geographic south. That’s why the north pole of a compass points toward north because that’s where Earth’s south magnetic pole is located and they attract.
What’s the best way to orient a compass?
Using the edge of the compass as a ruler, place it so that it creates a line between your current position and where you intend to go. Rotate the degree dial until the orienting arrow points to true north on the map. This will also align the compass’s orienting lines with the map’s north-south lines.
What’s the proper way to hold a lensatic compass?
With your course determined, hold the lensatic compass open and level in both hands, with the index finger of the right hand along the side of the compass. 3. Position the compass approximately halfway between the chin and the belt, keeping the North arrow under the Luminous Bezel Indicator.
Which is the best way to learn to read a compass?
Become familiar with Parts of the Compass before learning to read your compass. Hold your compass steadily in your hand so the baseplate is level and the direction-of-travel arrow is pointing straight away from you.
How do you read the bearing on a compass?
Keeping the compass flush with the ground and pointed towards the landmark, turn the rotating bezel of the compass until the North magnetic needle lines up with 0° on the compass (or “red is in the shed”). You’ve just captured the landmark’s bearing, which you can read at the top of the rotating housing, right under the index line.
