Which data must be recorded in the aircraft logbook when making a VOR operational check for IFR operations?

The accurate data that must be recorded in the aircraft logbook after conducting a VOR operational check for IFR operations is essential for ensuring compliance with regulatory requirements and safety. The correct information includes the date of the check, the place where the check was performed, the bearing error, and the pilot's signature.

Recording the date is important as it indicates when the VOR system was last verified, which is crucial for maintaining a schedule of checks. The place of check provides context pertinent to the VOR station being used, ensuring traceability and location-specific accuracy. Documenting the bearing error is vital, as it reflects the VOR's performance and any discrepancies noticed during the check. Finally, the pilot's signature certifies that the check was completed by a qualified individual, adding accountability to the logbook entry.

Together, this information helps in maintaining the effectiveness and safety of navigation using VOR systems in IFR conditions, ensuring pilots can depend on accurate navigation information.
