Which statement about required tests for flight operations is true?

• A. VOR check is included among the required tests for both VFR and IFR operations.
• B. VOR check is optional and not required.
• C. VOR check only applies to IFR operations.
• D. VOR check is a maintenance item for the engine.

Answer: (A)

Regular verification of navigation equipment accuracy is essential for safe flight. The VOR check confirms that the aircraft’s VOR receiver is displaying the correct indication within a defined tolerance, which is crucial because pilots may rely on VOR signals in either VFR or IFR conditions. Because navigation accuracy affects all types of flights, this check is treated as a required test for flight operations in general, not something optional or specific to only one operating regime. The VOR check can be performed using a VOT facility, a known VOR/DME checkpoint, or other approved means, and the results must be documented so you know the equipment is trustworthy before flight. It isn’t related to engine maintenance, and it isn’t correct to say it’s optional or limited to IFR only.
