It is very essential to have a full knowledge of reliability of navigation equipments, on which few reports have been seen so far. In this paper the writer intends to clarify the reliability of bottom logs by statistic disposal of failure data. The results of the researches are as follows: -1. The initial failure period lasts for 1 year after installation, then the random failure period follows it until 11 years after installation. 2.
