What is essential to record during a VOR operational check?

Recording all relevant information during a VOR operational check is critical for ensuring the accuracy and reliability of navigation data used in flight operations. The location of the operational check is necessary because navigation aids can be affected by terrain and other local factors, making it important to link the results to a specific geographic location.

The amount of bearing error is also essential as it provides specific details about the performance of the VOR equipment. Understanding the degree of error assists pilots in making informed decisions about navigation and helps to evaluate whether the VOR meets regulatory standards for use.

Additionally, the date of the check is vital for maintaining a record of when the operational check was performed. This contributes to a history of equipment performance and compliance with maintenance schedules, which can be particularly useful during flight planning and safety assessments.

Therefore, all these recorded elements together contribute to a comprehensive and effective operational check of the VOR system, ensuring planned flights can be conducted safely and accurately.
