What does the 'D' in DEPS stand for in the context of a VOR check log?

In the context of a VOR check log, the 'D' in DEPS stands for Date. When conducting a VOR check, pilots must log critical information about the VOR system's performance and accuracy, and the date is essential for record-keeping and compliance with regulations. This allows pilots and maintenance personnel to track the checks over time and ensure that the VOR is being operated within its required maintenance schedule and accuracy standards. Having the date recorded also helps in identifying any potential issues related to equipment performance, ensuring safe and reliable navigation.

While the other terms may relate to various aspects of flight operations and navigation, they do not pertain specifically to the VOR check log in the same standardized way that the date does.
