[WIP] Airborne Magnetic Anomaly Detector (MAD)

[keltos01]

basing sensor on OM 720 MAD sensor thanks to Lurker_lhb

The instrument had an effective range of 150 meters under average conditions and 250 meters under ideal conditions. The best height for an aircraft employing MAD was considered to be 10 to 50 meters depending on pilot's skill

2 set should be done : one US and one IJN following the spec here above but how do you set how deep the sensor sees ?
