  3. Heading (navigation) - Wikipedia

    en.wikipedia.org/wiki/Heading_(navigation)

    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. [1] 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]

  4. Standard rate turn - Wikipedia

    en.wikipedia.org/wiki/Standard_rate_turn

    A standard rate turn is defined as a 3° per second turn, which completes a 360° turn in 2 minutes. This is known as a 2-minute turn, or rate one (180°/min). Fast airplanes, or aircraft on certain precision approaches, use a half standard rate ('rate half' in some countries), but the definition of standard rate does not change.

    en.wikipedia.org/wiki/Straight-twin_engine

    During the development of the engine, it was found that a 360 degree crank angle was better suited to the use of a single carburettor than a 180 degree crank angle. [ 24 ] Following the trend created by the Triumph Speed Twin, the most common design used by British motorcycle manufacturers until the mid-1970s was a four-stroke straight-twin ...

  7. Degree (angle) - Wikipedia

    en.wikipedia.org/wiki/Degree_(angle)

    These considerations outweigh the convenient divisibility of the number 360. One complete turn (360°) is equal to 2 π radians, so 180° is equal to π radians, or equivalently, the degree is a mathematical constant: 1° = π ⁄ 180. One turn (corresponding to a cycle or revolution) is equal to 360°.

  8. Turn (angle) - Wikipedia

    en.wikipedia.org/wiki/Turn_(angle)

    A comparison of angles expressed in degrees and radians. The number 2 π (approximately 6.28) is the ratio of a circle's circumference to its radius , and the number of radians in one turn. The meaning of the symbol π {\displaystyle \pi } was not originally fixed to the ratio of the circumference and the diameter.

  9. Gradian - Wikipedia

    en.wikipedia.org/wiki/Gradian

    [18] [19] Today, the degree, ⁠ 1 / 360 ⁠ of a turn, or the mathematically more convenient radian, ⁠ 1 / 2 π ⁠ of a turn (used in the SI system of units) is generally used instead. In the 1970s – 1990s, most scientific calculators offered the gon (gradian), as well as radians and degrees, for their trigonometric functions . [ 23 ]
