'

Fore-and-aft inclinometer, or simply known as inclinometer, is an instrument used to measure the angular displacement of an object with respect to the horizontal plane. It is a mechanical device used to show the angle of inclination or declination of a surface such as a ship, aircraft, or railway carriage.

Inclinometers measure the angle of a surface relative to the horizontal plane, which is generally divided into four different types: 2-axis, 2-axis with single point, 3-axis, and 4-axis. The most common type is the 2-axis inclinometer which measures the fore-and-aft and transverse inclination of an object. The 2-axis with single point type measures the inclination at a single point of the object, while the 3-axis and 4-axis inclinometers measure the inclination of up to three or four points on the object.

Inclinometers are commonly used in many industries, such as navigation, shipbuilding, aviation, and railways. In navigation, inclinometers are used to measure the tilt of a ship's deck with respect to the horizontal plane. This allows navigators to determine the ship's heading, direction of travel, and speed. In shipbuilding, inclinometers are used to measure the angles of the hull, superstructure, and deck with respect to the horizontal plane. This allows ship designers to ensure the ship is properly balanced and will be stable in the water.

In aviation and railways, inclinometers are used to measure the angles of aircraft and railway carriages with respect to the track. This is important for ensuring smooth and safe operation of the vehicles. Inclinometers are also used in the oil and gas industry to measure the inclination of oil and gas wells. This helps geologists to determine the orientation of the borehole and the type of strata being drilled.

Inclinometers are important instruments used in many different industries to measure the angular displacement of an object. They are used to ensure that ships, aircraft, and railway carriages are stable and operate safely, and to determine the orientation of oil and gas wells.
