PAGE DATE High levels of noise were measured on the HFE/Central Station power and data interface lines during Flight #3 Integration Tests. Subsequent system tests including a special noise susceptibility test proved that the HFE induced noise levels were well below a margin that would adversely affect system performance.

Erratum Unfortunately, the original version of this article [1] contained an error. The superiority margin difference should be 5 % instead of 10 %. We performed a superiority test of two independent proportions with superiority margin difference of 5 % by PASS 11.0 software again, and the results were the same as mentioned in the paper before. The sentence in the "Sample size calculation" part...
