When is tape tracking best observed?

Tape tracking is best observed during the monthly checkout because this is a routine procedure designed to assess the equipment's overall health and performance. Monthly checkouts typically involve thorough inspections and tests that allow technicians to identify any issues, including those related to tape tracking. This timeframe helps ensure that any anomalies in the tracking process are detected before they lead to more significant problems, thereby maintaining safety and efficiency.

While initial equipment setup is crucial for ensuring proper functionality, any issues related to tape tracking may not be fully evident until the system has been in use and subjected to operational conditions. Maintenance inspections are also important, but they might not occur frequently enough to catch potential problems related to tape tracking in a timely manner. Observing tape tracking at the beginning of each flight is less ideal since it may not allow sufficient time to address potential issues discovered during pre-flight checks.
