Flight visibility

Flight visibility is the forward visibility from the cockpit of an aircraft in flight. It is used for VFR weather minima and can differ from the ground visibility reported at an aerodrome. It depends on haze, precipitation, cloud, smoke or other obscuring phenomena along the route. Before and during a VFR flight, make sure the required minima are met for the airspace and altitude, and if visibility becomes too low, turn back, divert or change to a safe alternative if qualified and permitted.
