Weather Calc vs Solar Time

If you’re a pilot, you often need to make lots of weather related calculations. Now there’s an easy solution, as close as your iPhone. Weather Calc performs the following weather relation calculations: Altimeter Setting - compute the altimeter setting based on elevation and station pressure Cricket Temperature - just for fun! This lets you estimate the temperature based on the chirp rate of a cricket Heat Index - compute the heat index based on the temperature and relative humidity Pressure - convert between hPa, atmospheres, psi, and inches and mm of mercury (Hg) Relative Humidity - compute the wet bulb and dewpoint based on the temperature, pressure, and relative humidity Speed Of Sound - displays the speed of sound in various units, given the temperature Standard Atmosphere - compute the temperature, pressure, density, viscosity, speed of sound, and more Station Pressure - compute the station pressure based on the elevation and altimeter setting. Temperature - convert between degrees Fahrenheit, Celsius, Kelvin, and Rankine Virtual Temperature - compute the virtual temperature based on the temperature, dewpoint, and pressure Vapor Pressure - com[ute the saturated and actual vapor pressure, as well as relative humidity Wet Bulb - compute the dewpoint and relative humidity based on the temperature, pressure, and wet bulb reading Wind Chill - compute the wind chill based on the temperature and wind speed Wind Speed - convert between knots, kilometers/hour, meters/second, miles/hour, feet/second Buy your copy now, and let Weather Calc take the drugery out of weather related calculations.

This application shows the apparent solar time, the time you would see on a sundial at your current location. It is the combination of the mean solar time (which depends on the longitude at your current position), the time difference from the solar equation which changes over the year because of the ecliptic path of the earth around the sun and optional daylight saving in the summer. That means the solar time at 12:00pm (noon) is the time of the highest sun position. Features: - see the time difference in detail - toggle the display of the seconds - toggle between 12 and 24 hours - the background color changes according to the time difference from the solar equation - the location is automatically updated when you move - supports all iPhones and all iPads - supports the iPad multitasking (split view, ...)
