Heading is typically based on cardinal directions, so 0° (or 360°) indicates a direction toward true north, 90° true east, 180° true south, and 270° true west. [1] TVMDC [ edit] Heading and track (A to B) 1 - True North 2 - Heading, the direction the vessel is "pointing towards" See more 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 … See more TVMDC is a mnemonic for converting true, magnetic and compass headings.

WebWhen the ship turns to point B, the ship ground velocity is the smallest, at this time the heading is θ 2, and the velocity over ground is V min. Owing to the uncertainty in the external environments, the difference between θ 1 and θ 2 is not exactly equal to 180 °. Hence, θ 1 cannot be directly used as the direction of the sea current.
