Which of the following methods utilizes interlaced ladders?

The SF Method, which stands for the "Sequential Flight Method," utilizes interlaced ladders as part of its operational process. This method is structured to efficiently survey areas where unexploded ordnance may be present by employing a systematic grid pattern that allows for thorough coverage.

The design of interlaced ladders is instrumental in ensuring that no spaces are overlooked during the UXO detection process. The interlacing offers the advantage of overlapping coverage in adjacent search lines, thereby increasing the likelihood of detecting ordnance that may have been missed with a more traditional linear approach.

This method integrates safety and thoroughness, which is critical in UXO activities, helping to minimize the risk associated with locating hazardous items. The systematic nature of the SF Method ensures a high level of accuracy in search efforts, which is essential in UXO operations.
