The course is to be distinguished from the heading, which is the direction where the watercraft's bow or the aircraft's nose is pointed. [1] [2] [3] The path that a vessel follows is called a track or, in the case of aircraft, ground track (also known as course made good or course over the ground). [1] The intended track is a route.
Therefore, to achieve a true course of 120°, one should follow a compass heading of 126°. True course is 120°, the Variation is 5° East and the Deviation is 1° East. T: 120° V: −5° M: 115° D: −1° C: 114° True course is 035°, the Variation is 4° West and the Deviation is 1° East. T: 035° V: +4° M: 039° D: −1° C: 038°
The ground vector represents the motion of the aircraft over the ground. It is described by ground track and ground speed. The ground vector is the resultant of algebraically adding the air vector and the wind vector. The wind triangle describes the relationships among the quantities used in air navigation. When two of the three vectors, or ...
The vector from A to B is the expected path for plane based on the initial heading (HDG) and true airspeed (TAS). The vector from B to C is the wind velocity (W/V), and the third vector is the actual track (TR) and ground speed (GS). The drift angle is marked in red.
The line connecting fixes is the track over the ground or sea bottom. The navigator compares the ground track with the navigational course for that leg of the intended route, in order to make a correction in "heading", the direction in which the craft is pointed to maintain its course in compensation for cross-currents of wind or water that may ...
Following a wild conference championship game weekend, Dan Wetzel, Ross Dellenger and SI's Pat Forde hop on to discuss the outcome of the final College Football Playoff rankings.
The actual course a vessel travels is referred to as the course over the ground. The current of the ocean alters this course whether pushing it away from its desired course or in the same direction. The vessel's speed through the water is referred to as the boatspeed [ 2 ] and the current can affect how fast or slow the vessel moves through the ...
Commissioned as a publicity stunt by THQ (a video game publisher that has since gone out of business) for Queen Elizabeth II, this gold-plated Wii stands out as a literal gem in gaming history.
