To use class G airport for IFR operations, the required facility is

• A. Facilities necessary to safely conduct IFR operation at time of operation
• B. METAR
• C. Served by an instrument approach
• D. Company ops frequency available to provide FICON

Answer: (A)

The key idea is that flying IFR into a Class G airport hinges on the airport having the facilities necessary to safely conduct IFR operations at the time you operate. That means the field must provide the safety-related infrastructure you need for IFR, such as appropriate weather reporting, lighting and runway equipment suitable for IFR conditions, navigational aids or published instrument procedures if you’re using them, and the necessary communications capability to support IFR operations. Merely having weather data like a METAR doesn’t by itself ensure safe IFR operation, and not every Class G airport offers an instrument approach, so relying on that alone isn’t sufficient. A company frequency for FICON is unrelated to the safety-ready facilities required for IFR at the airport.
