Which statement pertaining to the Terminal Aerodrome Forecast (TAF) is true?

The statement that SKC means the sky will be clear without significant weather is accurate because "SKC" is an abbreviation for "sky clear" in meteorological terms. A TAF is used to provide a weather forecast for the area around an airport, and when it indicates SKC, it specifically denotes that there are no clouds that would obscure visibility or impact flying conditions. This implies good weather, which is essential for safe aircraft operations.

In contrast, the other choices incorrectly describe SKC. They either suggest that it indicates poor weather conditions or cloud coverage, which is not the case. Understanding the terminology in aviation weather reports, such as TAFs, is crucial for pilots and aviation personnel to make informed decisions regarding flight operations.
