	The windshield wipers operate on the secondary DC bus and are controlled by a knob (see <xr id='fig:wipers'/>) on the upper console. The wipers have three speeds: slow, medium and fast. A position labeled PARK can be used to move the wiper to the up/vertical position to move it out of the way of the pilot's view. This position should be used momentarily before turning the wipers off to stow the wipers. The wipers should only be used on wet glass.

−	Pilots should be mindful that in hot and/or humid weather, performance will be decreased due to the increased density altitude. It will require more power/collective to hover, and more power will be required in cruise. Pilots should be aware of the different types of altitude and how they affect performance:
−
−	* Indicated Altitude - The altitude as shown on the aircraft altitude indicator.
−	* True Altitude - The actual altitude of the aircraft above sea level.
−	* Pressure Altitude - The altitude above the 29.92 in Hg datum plane. Equal to true altitude on a day with standard pressure (29.92 in Hg).
−	* Density Altitude - The pressure altitude adjusted for temperature. Reflects the expected aircraft performance.
−	* Absolute Altitude - The altitude of the aircraft above the ground. Displayed on the radar altimeter.
−
−	To calculate density altitude, use the chart shown in <xr id="fig:da"/>. To use the chart, start on the left-hand side at the outside temperature and move horizontally until reaching the diagonal line for the pressure altitude. Then drop vertically to read the density altitude. In the example shown with dotted lines, the outside temperature is 25C, the pressure altitude is 5300 resulting in a density altitude of 7800.
−
−	To a lesser extent than temperature, high humidity can also have an effect on performance as well, particularly in combination with high temperatures. A small buffer should be added to the calculated density altitude when humidity is high.

−	The S-58/H-34 can be operated using either "basic" weather or "advanced" weather. The weather model used is selected from the @Option menu. Turn on the "Adv. Wx" to enable advanced weather. In basic weather mode, relatively mild temperature and humidity variations will be simulated, but no wind or clouds unless requested. With advanced weather, the helicopter will react to wind, clouds, precipitation, etc. These weather systems are described in the following section.
−
−	~~==== Basic Weather ====~~
−
−	When in basic weather mode, chat commands can be used to set various weather conditions (e.g., visibility, temperature, humidity). When in IMC, the inside windows will be made opaque to simulate flight in fog or clouds. You can also set a "ceiling", the height of the cloud layer. This feature can be used in conjunction with the ILS approach system. Within the basic weather system, the following weather submodes can be set:
−	*auto - variations in temperature and humidity are simulated based on time and position within the helicopter
−	*static - weather conditions remain static according to user settings. Setting any weather condition to a set value will cause the model to enter static mode.
−	*disabled - no weather is simulated other than constant 20C temperature.

−	When advanced weather is enabled, weather will be generated by the Shergood Weather Simulator (SWS). SWS simulates grid-wide weather patterns with charts and data that can be queried at http://www.shergoodaviation.com/weather.php . Each time the aircraft enters a new region, it will query the SWS server for the weather conditions in that region including temperature, humidity, winds, altimeter setting, cloud bases and visibility.
