With Flight Simulator, weather conditions are controlled from the World/Weather menu. You can change conditions on a global basis, whereby the same conditions exist all across the Flight Simulator Earth, or change and define individual areas. In addition to a global setting, you can program two defined weather areas. This capability is useful for programming different weather conditions at the departure and destination airports for instrument flights. For example, you may want to program clouds only 100' above the ground at the departure airport. At the destination airport, however, you may need a higher ceiling. Low visibilities significantly increase the difficulty of the flights and may hamper learning, because it is tremendously helpful to correlate the out the wind screen view to the instrument indications.
