The simplest way to find it is to read the aircraft’s compass. This will show you the direction you are facing with reference, in degrees, from magnetic north. By reading the bearing given on the compass and knowing that the compass is always aligned with the magnetic north, you can always work out which way you are facing.
How do you find the true bearing of a magnetic bearing?
True Bearing(T.B) = [Magnetic Bearing(M.B) + Declination] 2. If Declination is West. True Bearing = [Magnetic Bearing – Declination] Calculate True Bearing From Magnetic Bearing- Example. Example: The magnetic bearing of a line OP is 89°45՛.
How do you find the true bearing if the declination is?
If Declination is West If the magnetic declination at a place at the time of observation is known, the true bearing of a line can be calculated from its magnetic bearing and vice-versa. The following rules are applied to determine the true bearing if the magnetic declination is known:
What is the magnetic bearing to the station on my heading?
On a magnetic heading of 160°, the magnetic bearing to the station is: Looking at the figure, I see a needle pointing to 045°. Therefore, I conclude that when my heading is magnetic north (as the heading of the aircraft is shown in the figure), the magnetic bearing to the station would be 045°.
How do you find the magnetic direction of a runway?
Runways are named after their magnetic headings. To convert from True to Magnetic, use " East is least (i.e. subtract), West is best (i.e. add) ". If you are standing at this location looking in the direction 007 T, to find the direction you are looking in magnetic terms, subtract the 4 degrees E variation to get 003 M.

How is magnetic track calculated?
To get the true heading, you need to first read the magnetic compass, then either add an Easterly, or subtract a Westerly, magnetic variation; based on the isogonic lines. When converting true to magnetic heading, you'd do the opposite and subtract an Easterly, or add a Westerly, magnetic variation.
What is the difference between true bearing and magnetic bearing?
True bearing and magnetic bearing in geography generally refer to true north and magnetic north. True north is the direction pointing to the North Pole. On the map, true north is represented by meridians or lines of longitudes. On the other hand, magnetic north is the direction which points to the magnetic pole.
What is magnetic bearing in navigation?
If you are taking a bearing off a real point on the landscape with a compass, you are using your compass to measure the angle clockwise from magnetic north to this point on the landscape. This is called a magnetic bearing. Remember that the bearing is measured clockwise.

Where are magnetic bearings used?
Magnetic bearings are used in industrial machines such as pumps, compressors, turbines and generators are appealing because they are generally more efficient, quieter and do not require lubrication. Magnetic bearings can also be used to support maglev trains for transportation.
How does a magnetic bearing compressor work?
The magnetic bearings allow the compressor to operate without the use of oil for lubrication, which reduces energy losses due to friction and increases the heat transfer efficiency of the chiller, because no oil enters the evaporator or the condenser.
How long do magnetic bearings last?
Non-contact design which improves reliability – magnetic bearings are designed to last 25 plus years.
What is relative bearing Aviation?
Relative Bearing (RB): The angular difference between the aircraft heading and the direction to the station, measured clockwise from the nose of the aircraft.
What is magnetic heading in aviation?
Magnetic heading is your direction relative to magnetic north, read from your magnetic compass. True heading is your direction relative to true north, or the geographic north pole. The difference is due to the magnetic north pole and geographic north pole being hundreds of miles apart.
How to get the magnetic heading?
To get the Magnetic Heading, you just read it off the magnetic compass. To get the True Heading, you need to first read the magnetic compass, then either add an Easterly, or subtract a Westerly, magnetic variation; based upon the isogonic lines on your sectional (the purple dashed lines labeled 5°W, 3°E, etc).
How do you calculate headings?
Heading is typically based on compass directions, so 0° (or 360°) indicates a direction toward true North, 90° indicates a direction toward true East, 180° is true South, and 270° is true West.
Do pilots use magnetic or true north?
Most large aircraft use inertial reference units and flight management systems that complete calculations using True North and add magnetic variation values from tables to display information to pilots.
Is Skyvector true or magnetic?
On skyvector, the correction, for magnetic heading, that comes up doesnt always match what the agnostic lines dictate. For example a direct, true course, from KBOS to KALB is 282. Skyvector says magnetic course is 298, a 16 degree difference.
Are VOR headings true or magnetic?
VOR degrees are magnetic, not true, so you can read your magnetic course for that location right from the VOR rose. Again, the difference between the true course you’ve drawn on your chart and the magnetic course that runs through the VOR rose is the magnetic variation.
Calculate True Bearing From Magnetic Bearing
If the magnetic declination at a place at the time of observation is known, the true bearing of a line can be calculated from its magnetic bearing and vice-versa.
Determination of True Bearing From Magnetic Bearing Rules
The following rules are applied to determine the true bearing if the magnetic declination is known:
Calculate True Bearing From Magnetic Bearing- Example
Example: The magnetic bearing of a line OP is 89°45՛. Determine the true bearing if – a) The magnetic declination is 5°30՛ E. b) The magnetic declination is 4°15՛ W.
Magnetic Compass Deviation vs Variation – Video Transcript
Today in this video we’re going to talk a little bit about the magnetic compass. Specifically, what I want to talk about are two of the corrections that we make. One is called deviation and the other is called variation.
Deviation
So, we’re out here at the airplane now, and what we have here is a compass, regular old-fashioned compass, and what we’re going to talk a little bit about is deviation. Really what deviation is, is simply a magnetic interference that causes the compass to show incorrectly.
Variation
Okay so now we’re back in the classroom again. Now we’re going to talk a little bit more about variation. Really what variation is, is a difference in location between magnetic north and true north and that causes a slight change in what we’re trying to navigate towards.
What happens to your bearing when you fly from one airport to another?
If you are going directly from one airport to the other, your course and bearing will be the same along the route of flight. If you are flying from an airport to a VOR to another airport, your course will change in each leg, as will your bearing.
What is the bearing of the destination airport off of your departure airport?
In this instance the bearing of the destination airport off of your departing airport is also 090. This is also the direction you want to track the airplane ...
What are the two main categories of direction of flight?
Heading and track are really the two main categories of direction of flight, but they are further broken down into bearing and course which we will cover next.
What is the meaning of heading in airplanes?
By definition though, heading is actually just the direction that the nose is pointed. This does not factor for wind, or the actual movement of the airplane across the ground.
Is 090 a compass?
Your (compass) heading may or may not be 090, depending on both the wind correction angle (which you can solve for using an analog or digital e6-b calculator), magnetic variation of your location, and any deviation of the compass itself onboard your aircraft. Remember the following calculation to solve for your compass heading in order to fly your desired track or course (both 090).
