What must be true about the visibility for VFR flight alternate minimums?

For VFR flight alternate minimums, it is essential that visibility meets specific criteria to ensure that pilots can safely navigate and land at the alternate airfield should they need to alter their flight plan. The requirement for a minimum visibility of at least 8 kilometers is in place to provide pilots with adequate visual reference to identify and maneuver to the alternate airport. This standard takes into account factors such as weather conditions, flight safety protocols, and operational procedures, all of which are critical for maintaining safety during flight operations.

Having a minimum visibility of 8 kilometers ensures that pilots can comfortably assess the airfield environment, making it easier to execute landing procedures and safely navigate in the vicinity of the airport. This visibility requirement supports the overarching goal of VFR operations, which is to maintain situational awareness and make informed decisions during flight.
