MGL SP-6 Magnetometer

MFR Model# SP-6
Overview
|
The SP-6 magnetometer is a three axis, tilt compensated electronic compass system. It outputs magnetic heading information. In the case of a standalone SP-6, tilt compensation is performed by deriving the attitude of the SP-6 sensor using on-board accelerometers which are used to vector the direction of gravity. The magnetic field is measured using three magnetometers which are mounted perpendicular to each other resulting in three magnetic force vectors. Using three magnetic force vectors and knowledge of attitude allows calculation of magnetic heading even if the SP-6 is not horizontal. if you have a SP-7 AHRS connected to the same Airtalk bus as the SP-6, the SP-6 will use the attitude data from the SP-7 to calculate the heading. If your SP-6 is set to gyro mode and horizon data is being received, your SP-6 will use the gyro derived horizon rather than the built in accelerometers for tilt compensation. In this case, heading is correct even during turns. |

Please note, Aircraft Spruce's personnel are not certified aircraft mechanics and can only provide general support and ideas, which should not be relied upon or implemented in lieu of consulting an A&P or other qualified technician. Aircraft Spruce assumes no responsibility or liability for any issue or problem which may arise from any repair, modification or other work done from this knowledge base. Any product eligibility information provided here is based on general application guides and we recommend always referring to your specific aircraft parts manual, the parts manufacturer or consulting with a qualified mechanic.
Per the manual, the SP-6 outputs magnetic heading information. Attitude data would come from an SP-7.
We have added the dimensional drawing to the webpage. Please review it there.
This unit will provide rate of turn and magnetic heading.
This is a remote magnetometer used for DG/HSI for heading.
Yes, when you add on the SP-6 it will allow for the Compass with slip indicator to function.
No, this is only used for compatible MGL instruments. The AV-30 is a non-slaved DG, so it does not require a remote magnetometer.
