In navigation, the course of a watercraft or aircraft is the cardinal direction in which the craft is to be steered. The course is to be distinguished from the heading, which is the compass direction in which the craft's bow or nose is pointed. Contents
The diffrence between a course and heading is the wind correction angle - do a wind triangle problem to find that - Oh never had groundschool - too bad! Whats the difference between OAT and TAT and how/why?
In navigation, the course of a vessel or aircraft is the cardinal direction in which the craft is to be steered. The course is to be distinguished from the heading, which is the compass direction in which the craft's bow or nose is pointed. 1 Course, track, route and heading.
So what is the difference between heading, bearing, course, and track anyways? Heading is the direction the airplane is pointed, whereas track is the actual direction of the airplane tracking across the ground. Bearing is the angle between any two points, whereas course is your intended path of travel to your destination.
In aviation, where winds can and often will push you off-course, heading is rarely equal to bearing when the total travel distance is large. This makes for frequent course corrections to account for wind. In my opinion, direction is the most basic term of all, and describes a directed vector between two points.

the intended direction of travelThe course is the intended direction of travel. Ideally (but rarely) it is the same as heading. On a GPS receiver, the actual direction of motion is called course over ground (COG) or, on some units, track.
Definitions. Heading. The direction in which the longitudinal axis of an aircraft is pointed, usually expressed in degrees from North (true, magnetic, compass or grid). (
Course Over Ground (COG) is the actual direction of motion (the intended direction of travel). While heading is the direction in which a vehicle/vessel is pointing at any given moment (https://www.applanix.com/news/blog-course-heading-bearing/).

[′kȯrs ‚līn] (navigation) A line of position plotted on a chart, parallel or substantially parallel to the intended course of a craft, showing whether the craft is to the right or the left of its course.
Definition of compass course : the course with respect to true north in which a ship or an aircraft is intended to travel.
A ship's true course is determined by the direction from the ship to the geographic north pole (also called true north). Navigation charts andthe compass are labeled with true north, but setting a ship's course is not merely a matter of steering in relation to the north pole.
"A track is a line on a chart or across the terrain that an airplane is following or intending to follow. It is a vector, which means it is given as a starting point and a heading. A course is a line between two points on earth. Usually given by stating the names of the starting and ending points."
COG, Course Over Ground, indicates the direction of the boat's heading relative to the land. Over ground means "in relation to the earth", see also the term SOG. Therefore, COG means the true direction free from the effects of sea currents.
Course Over Ground is the actual direction of progress of a vessel, between two points, with respect to the surface of the earth. The vessel's Heading may differ from the Course over ground due to the effects of wind, Tide and currents.
Course is the direction in which the aircraft is flying over the ground. Heading is the direction in which the aircraft is pointing.
Professional Pilot Training (includes ground studies) - Calculating TRUE headings... - First off, hopefully i've posted this in the right forum. If not - apologies. Secondly - i'm currently going over some notes and am trying to brush up on my knowledge. Im currently stuck on what is a seemingly easy question Given

Heading is the direction the airplane is pointed, whereas track is the actual direction of the airplane tracking across the ground. Bearing is the angle between any two points, whereas course is your intended path of travel to your destination. In the rest of this post we’ll elaborate on each of these points and then also provide ...
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.
Bearing can be confusing sometimes because has some overlap with course. Bearing is simply the angle or direction between two points. A practical application of this is in VOR navigation. It’s a common thing to hear someone say “we are bearing 090 from the station”.
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.
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 ...
It’s confusing because they are often (incorrectly) used interchangeably in conversation: Heading, bearing, course, and track. Even correctly used by ATC, “on course heading” is still a little misleading because below you’ll see they’re practically referring to “course” and not “heading”.
In contrast, GPS RNAV systems may use an algorithm, which applies the local magnetic variation and may produce small differences in the displayed course. However, both methods of navigation should produce the same desired ground track when using approved, IFR navigation system.
Heading. Heading is the direction in which a vehicle/vessel is pointing at any given moment. It is expressed as the angular distance relative to north, usually 000° at north, clockwise through 359°, in degrees of either true, magnetic, or compass direction.
Ideally (but rarely) it is the same as heading. On a GPS receiver, the actual direction of motion is called course over ground (COG) or, on some units, track.
A bearing is the direction from one place to another, measured in degrees of angle with respect to an accepted reference line. When using compass bearings, the reference line is north, so “the lighthouse is on a bearing of 270°” means “the lighthouse is to the west of us.”.
It is a constantly changing value as a vessel yaws back and forth across the course due to the combined effects of sea, wind, and steering error. For example, on a boat the helmsman may be trying to steer a course of 180°, but the heading one moment is 188° and the next moment it is 074°. The course remains 180°.
Heading is confusing for some people and is often misused. Typically, when someone is asked what their heading is, they’ll say where they are headed. But those are two different words. If you’re going back to the marina, that isn’t necessarily your heading at all.
Course is what many people mean when they say heading. Your desired course is the intended direction you planned on going. So your course may have been due east but you had to navigate around an island so your heading changed to accommodate that. Your course and intended path remains the same, however.
Bearing may overlap with course and heading but it doesn’t have to. Instead, bearing is the angle in degrees between north and the direction of your destination. This is also called a navigation bearing or magnetic bearing. But that’s not the only bearing you need to know about. There’s also relative bearing.
Relative bearing is similar to navigational bearing. In this case, however, we’re not calculating degrees between north and the destination. It’s between the heading of the vessel and the destination. So your relative bearing could be 0 degrees if your heading and course are all aligned.
You’ll also run across the words tack and track in nautical use sometimes. They are not the same term and refer to different things.
Understanding magnetic or true bearing vs relative bearing vs true course can seem daunting. However, it’s not that difficult once you get the hang of it. Basically there are three important numbers involved here and if you know two you can determine the third.
Many modern boaters rely entirely on technology to help them navigate. And there’s no doubt GPS and other electronic tools are invaluable and have made boating safer and easier. But being able to calculate heading, course and bearing without technology could be extremely important.
Bearing is regularly defined as the direction (relative to true north) in which your destination lies. If you could go in a straight line to your destination, this would be the most direct way of getting there.
In aviation, where winds can and often will push you off-course, heading is rarely equal to bearing when the total travel distance is large. This makes for frequent course corrections to account for wind. In my opinion, direction is the most basic term of all, and describes a directed vector between two points.
Heading is the direction in which the aircraft is pointing. See it like this... When Tomtom directs you from Amsterdam to Barcelona via Paris, Barcelona is your final 'course', but for now... you're 'heading' towards Paris... (taking in mind that you just left from Amsterdam...)
When in NAV mode the autopilot will steer the plane to fly along a radial of the VOR that the NAV radio is tuned to. The course knob is used to select the desired radial. This will make the plane fly along a certain path but only when there is a suitable VOR available.
307. If you're using the autopilot in the heading mode, it will hold the magnetic (compass) heading you were holding when you engaged the autopilot. If there's a crosswind, the a/p will still hold that heading, but the airplane's ground track will drift with the wind.
Any difference between the heading and course is due to the motion of the underlying medium, the air or water, or other effects like skidding or slipping. The difference is known as the drift, and can be determined by the wind triangle. At least seven ways to measure the heading of a vehicle have been described.
In navigation, the heading of a vessel or aircraft is the compass direction in which the craft's bow or nose is pointed. Note that the heading may not necessarily be the direction that the vehicle actually travels, which is known as its course or track.
Course directions are specified in degrees from north, either true or magnetic. In aviation, north is usually expressed as 360°. Navigators used ordinal directions, instead of compass degrees, e.g. "northeast" instead of 45° until the mid-20th century when the use of degrees became prevalent.

A, B - Vessel's track. The path that a vessel follows over the ground is called a ground track, course made good or course over the ground. For an aircraft it is simply its track. The intended track is a route. For ships and aircraft, routes are typically straight-line segments between waypoints. A navigator determines the bearing (the compass ...
Because water currents or wind can cause a craft to drift off course, a navigator sets a course to steer that compensates for drift. The helmsman or pilot points the craft on a heading that corresponds to the course to steer.
