For A and C to face each other, both would have to face North. To "keep to a bearing" is not, in general, the same as going in a fixed direction along a great circle. Conversely, one can keep to a great circle and the bearing may change. Thus the bearing of a straight path crossing the North Pole changes abruptly at the Pole from North to South.
A bootleg turn is a driving maneuver intended to reverse the direction of travel of a forward-moving automobile by 180 degrees in a minimum amount of time while staying within the width of a two-lane road. [1] This maneuver is also known as a smuggler's turn, powerslide, or simply bootlegger.
The narrowest J-turn was performed in a Renault Twingo, between barriers set 3.78 metres (12.4 ft) apart.The diagonal length of the car, 3.70 metres (12.1 ft), meant stunt driver Terry Grant had a gap of 4 centimetres (1.6 in) on each side.
The Geographic North Pole around which the Earth rotates is not in exactly the same position as the Magnetic North Pole. From any position on the globe, a direction can be determined to either the Geographic North Pole or to the Magnetic North Pole. These directions are expressed in degrees from 0–360°, and also fractions of a degree.
A pilot would begin to roll the aircraft out of the bank at 308 degrees read from the compass to fly on a north heading. Making a turn towards south from west the pilot would have to roll the aircraft out of the turn when the compass was 45 degrees minus half the bank angle (from west to south at 90 knots 180-45+7=142, from east to south 180+45 ...
The azimuth is the angle between the north vector and the star's vector on the horizontal plane. [2] Azimuth is usually measured in degrees (°), in the positive range 0° to 360° or in the signed range -180° to +180°.
Direction determination refers to the ways in which a cardinal direction or compass point can be determined in navigation and wayfinding.The most direct method is using a compass (magnetic compass or gyrocompass), but indirect methods exist, based on the Sun path (unaided or by using a watch or sundial), the stars, and satellite navigation.
32-point compass rose. The points of the compass are a set of horizontal, radially arrayed compass directions (or azimuths) used in navigation and cartography.A compass rose is primarily composed of four cardinal directions—north, east, south, and west—each separated by 90 degrees, and secondarily divided by four ordinal (intercardinal) directions—northeast, southeast, southwest, and ...
