Proposed RSM Location Check
The installer must determine the best RSM location given the above factors. With proper
training and careful application, a navigation quality handheld compass (i.e., hiking
compass) can be used to find a magnetically quiet area free from the effects of magnetic
disturbances from flight controls, autopilot servos, strobes, or any other large magnetic
field appliance. The HMR2300 Smart Digital Magnetometer is a more effective tool to
properly choose an RSM location, it detects magnetic fields with more precision and
should be used with TechNote TN2010-01 to identify RSM locations that are free from
magnetic interference.
The RSM can detect magnetic fields in three dimensions. This means that magnetic
influences below the RSM can also affect performance. Be sure to evaluate potential
magnetic influences above and below the RSM.
