What do Visual Flight Rules (VFR) depend on?

Visual Flight Rules (VFR) primarily depend on weather and visibility conditions. Under VFR, pilots navigate and operate their aircraft by visual reference to the ground and other landmarks, rather than relying solely on instruments. For VFR to be applicable, there must be adequate visibility to see other aircraft and the terrain. This typically means that the weather conditions must meet certain minimums established by aviation regulations, which include cloud cover, visibility distance, and other meteorological factors that can affect safe navigation.

When visibility is poor or weather conditions are threatening, VFR cannot be safely maintained, and pilots must switch to Instrument Flight Rules (IFR) for navigation. Therefore, understanding the requirements for visibility and weather is crucial for pilots operating under VFR.
