What should be included in a VOR check log?

In the context of a VOR check log, it is essential to include specific information that reflects the accuracy and validity of the VOR navigation signal. The reason the correct choice includes the date, place, bearing error, and signature is that these elements are critical for documenting the performance of the VOR system during a check.

The date indicates when the check was performed, which is necessary for maintenance records and compliance with regulations that dictate how frequently VOR checks must be conducted. The place refers to the location where the check was done, important for establishing reliability in varying geographic areas.

The bearing error is crucial as it quantifies the deviation between the received VOR signal and the true heading. This value must be within acceptable limits to ensure safe navigation. Lastly, the signature serves as verification of who performed the check, providing accountability and traceability.

Other options do not prioritize the specific information necessary for the VOR check log. While they may contain useful data, they do not capture the essential details required for ensuring navigational integrity and compliance with aviation standards.
