Deployment silbo-20110623T1215
Pilot Notes
Silbo aborted around 07:00 EST for a leak detect in the aft compartment. ABORT HISTORY: total since reset: 18 ABORT HISTORY: last abort cause: MS_ABORT_LEAK ABORT HISTORY: last abort details: There is a leak in the aft compartment. ABORT HISTORY: last abort time: 2011-11-05T10:17:30 ABORT HISTORY: last abort segment: silbo-2011-305-0-19 (0169.0019) ABORT HISTORY: last abort mission: LEIF.MI At 940m on the second dive of segment 2011-305-0-19, the aft end leak detector detected a leak. A leak is defined as voltage lower than 2.0 V. The data resolution was infrequent for this sensor (~60 secs). We were able to see from data a low voltage reading (~1.2 V) around the time of the abort. There were no other readings < 2.0 V as the glider surfaced, however, in the surface dialog we saw the following sensor value: sensor:m_leakdetect_voltage(volts)=1.15299145299145 54.152 secs ago By the time I was able to get to the glider, the leakdetect voltage was back above 2.5 It is possible then that no other low voltages were recorded due to the low recording frequency for this sensor, or another anomaly. ##Actions taken: 17:30 EST Running a single yo to 30m with the following configuration: Added sensors to the SBD/MBD lists: m_leakdetect_voltage m_leakdetect_voltage_forward m_battery_inst m_vacuum put c_leakdetect_time 0 (was 60) New leif.mi mission, with overtime = 7200 New yo10.ma, single yo to 30m.
