Compensation place
A compensation area (also compensation surface or compensation disk ) is a specially selected and set up place on airfields , where the compensation of magnetic field sensitive sensors in aircraft (aviation compass and induction probe ) as well as the determination of the radio deviation (misdirection) is possible.
On the compensation area, aircraft can be rotated according to a compensation rose painted on the ground . This makes it possible to compensate the compass in which an attempt is made to correct the error of a declination or to specify a deviation (correction value) for the residual error. The aircraft is rotated in 30-degree steps on the compensation surface and then the course set on the field and the course displayed on the on-board compass are compared.
Due to magnetic components such as iron components and current-carrying conductors in aircraft, the magnetic compass shows a declination, which can be compensated for by a compensator . The compensator is a device on magnetic or radio compasses with which the display errors can be eliminated. On the magnetic compass it contains weak magnets, the displacement of which compensates for the fixed magnetic field of the aircraft. On the radio compass , the compensator is used to adjust the angle difference between the antenna position and the Selsyn encoder .
