How does rain impact visibility for pilots?

Rain primarily impacts visibility by reducing it, which is crucial for pilots to understand. When rain falls, it creates additional moisture in the air that can lead to a number of visibility issues. For instance, rain droplets can scatter light, making distant objects harder to see. This is especially pronounced during heavy rain, where the intensity and volume of water obscures vision both outside the cockpit and through the aircraft's windscreen.

Moreover, rain can lead to the formation of mist or fog as water evaporates and saturates the humidity in the air. Low visibility conditions, often brought on by rain, are critical for flight operations, influencing decisions regarding take-offs, landings, and in-flight navigation. Pilots must be trained to gauge visibility and understand the limitations imposed by such weather conditions when assessing their ability to fly safely. This is why recognizing the impact of rain on visibility is essential for flight safety and effective piloting.
