Magnetic Effect

RTCA DO-160 – Section 15.0 – Magnetic Effect

 

This test determines the magnetic effect of the equipment and is mainly intended for finding or proving the closest distance to compasses or compass sensors (flux gates) at which that unit is allowed to be installed.
This test ensures that equipment can operate properly without interference which may affect the nearby equipment, determining equipment compliance with the applicable equipment performance standard or assisting the installer in choosing the proper location of the equipment in the aircraft.

 

Test Description
The magnetic effect of the equipment shall be determined in terms of the equivalent deflection of a free magnet in a uniform magnetic field (as produced by the earth) having a horizontal intensity of 14.4 A/m ±10% when the equipment under test is positioned on the east-west line through the pivot of a magnet.
This measurement may be performed with either an uncompensated compass or an equivalent magnetic sensor.

 

DO-160 is a standard for environmental test on avionics equipment published by RTCA, the Radio Technical Commission for Aeronautics. The DO 160 G was amended and now all guideline inside it are replaced by the DO 357.
On our website you can find only some abstracts of the document, for the full text of the guideline you have to purchased it from RTCA.
We remember you that now DO 160 G cannot be read without DO 357.
If you need any interpretation regarding the text of such standard, please contact CELAB.
CELAB is the only Italian (and one of the few European) member of the RTCA Special Committee 135, the commettee for devolpment of DO 160 G.
