DZMx Plus Data Logging
The DZMx Plus provides several data logging functions.
DZMx Plus Flight Data Recorder
The DZMx Plus has an inbuilt flight data recording function that includes an inertial
measurement unit and barometric pressure sensor. The output from these sensors is logged
at one second intervals.
The following raw sensor data is logged:
»
Angular rotation in all 3 axes (radians per second, relative to the DZMx Plus)
»
Acceleration in all 3 axes (G force, relative to the DZMx Plus)
The inertial data is fused and logged to provide:
»
Airframe pitch (degrees)
»
Airframe roll (degrees)
»
Pressure (millibars)
»
Pressure altitude (reference to 1013.25 millibars)
Disclaimer
The Flight Data Recording system in the DZMx Plus uses a six degree of freedom sensor fusion
technique and thus all pitch and roll values output are a best estimate based on measured angular
rate (prone to drift) and estimated gravity vector (which can be distorted by accelerations). This
must not be used for navigational or control purposes.
