<p><b>New page</b></p><div>[[image:Leeway_Angle.jpg|thumb|left]] [[image:Leeway_Components.jpg|thumb|left]] [[image:SAR_Objects.jpg|thumb|right]] '''Leeway''' refers to the lateral movement of a ship or aircraft to the leeward side of its intended course due to wind, currents, or other external forces. This phenomenon is a critical consideration in [[navigation]] and [[aeronautics]].<br />
<br />
== Causes of Leeway ==<br />
Leeway is primarily caused by the following factors:<br />
* [[Wind]]: The force of the wind can push a vessel or aircraft sideways.<br />
* [[Currents]]: Ocean currents can alter the course of a ship.<br />
* [[Tides]]: Tidal movements can also contribute to leeway.<br />
<br />
== Effects of Leeway ==<br />
Leeway can have several effects on navigation:<br />
* **Course Deviation**: The intended course of a vessel or aircraft can be significantly altered.<br />
* **Fuel Consumption**: Additional fuel may be required to correct the course.<br />
* **Safety**: Navigational safety can be compromised if leeway is not properly accounted for.<br />
<br />
== Calculating Leeway ==<br />
Navigators and pilots use various methods to calculate and compensate for leeway:<br />
* **Dead Reckoning**: Estimating the position based on speed, time, and course.<br />
* **Electronic Navigation Systems**: Using GPS and other systems to monitor and adjust the course.<br />
* **Visual Observations**: Observing landmarks or celestial bodies to determine the actual position.<br />
<br />
== Mitigating Leeway ==<br />
Several strategies can be employed to mitigate the effects of leeway:<br />
* **Course Adjustment**: Regularly adjusting the course to counteract leeway.<br />
* **Speed Adjustment**: Increasing or decreasing speed to minimize the impact of external forces.<br />
* **Route Planning**: Planning routes that take into account prevailing winds and currents.<br />
