Highway Crosswind Calculator
This calculator requires the use of Javascript enabled and capable browsers. It is to determine the subjected speed of crosswinds on a loaded truck or high profile vehicle on the highway. All entries should be numeric, assuming either knots or MPH. The direction of the highway and relative wind is from, should be in compass headings. North is 360 degrees, South is 180. East is 90 and West is 270. Normally 10 degree deviations are accurate enough to give a good calculation; the calculator will accept as accurate an entry as you can determine. Odd numbered highways are generally North and South while even numbers are generally East and West, though they are prone toward directional changes for short distances. It is best to pre-plan the trip using a compass and a map to give accurate information. The answers are returned as numbers indicating the knots or MPH of the crosswind as it "feels" to the vehicle (the side directional force), based on your entries of directions and speed, and the potential reduction in forward highway speed, or power equivalent, in knots or MPH. High profile vehicles, including trucks with loads, are prone toward problems from crosswinds in the mountain passes and desert areas. If the calculated crosswind is above the rated loaded vehicle safety limits, the vehicle should not be exposed to the hazard. Use care!
