Crew 183 Operations Report 24-11-2017
Name of person filing report: Ashton Stoop
Power system – SOC
Notes on non-nominal systems:
The power system calculates SOC based on an algorithm, it is not a measured value. This has been causing strange fluctuations on when reading the SOC.

Questions, concerns and requests to Mission Support:
-Dear mission support, how exactly does the SOC reading on the power system operate? We have had fluctuations in the SOC readings which do not correlate closely with our estimated values of power generation and power consumption (Please refer to SOC Readings table above).
-We have no additional supply of gasoline for the ATVs. All that’s left is what’s in the vehicles. We need fuel ASAP!
