Magnetic Deviation
Magnetic Deviation is the phenomenon whereby the magnetic fields within an aircraft interfere with the proper functioning of the magnetic instruments and cause errors in the readings of the magnetic compass. This error is caused by the magnetic impact of aircraft materials on the instruments and is different on each heading.
The deviations caused by magnetic fields need to be corrected for to ensure accurate navigation. This correction is accomplished by referring to a compass correction card and making the necessary adjustments to the compass readings. The magnetic deviation must be accounted for to ensure that the aircraft is pointing in the correct direction and to prevent navigation errors.
Magnetic deviation can also occur in other settings, such as in maritime navigation, where the magnetic fields of the ship can impact the readings of the compass, leading to navigational errors. However, regardless of the setting, it is essential to account for magnetic deviation to ensure accurate navigation and safe travel.
