Density Altitude + vs FlightReady E6B

Instant and location accurate Density Altitude calculator/instrument app for iPhone and iPad that also finds relative air density (RAD), altimeter setting, relative humidity, specific humidity (grains/lb) and more. Super useful for pilots, especially in the backcountry. Many other uses for engine tuning, racing, sports, etc. * Seamlessly integrates weather data, GPS and your phone's onboard barometer to quickly and accurately calculate your density altitude, altimeter setting, relative air density, and more. * Takes humidity into account in all calculations, making it more accurate than the typical dry bulb approximation formula used by AWOS/ASOS, etc. * Works anywhere. Great without cellular connection as well, which makes it all the more useful in the backcountry and far away from ASOS/AWOS stations. * Location Search: Find atmospheric data (Density Altitude, etc.) at any point on Earth, from anywhere! Data Sensed and Calculated (all calculated with humidity): * Density Altitude * GPS Altitude * Temperature * Altimeter Setting * Absolute Pressure * Dew Point * Relative Humidity * Specific Humidity (grains/pound) * Air Density * Relative Air Density (RAD) * Dyno Correction The quickest way to get your Density Altitude! On the iPhone 6/6+ and newer iPads, it will use the built-in barometer and GPS. If you're in cell range, you don't need to supply any data. If you're out of cell range, all you need to supply is the outside air temperature. Designed not to need an internet connection, so it will work anytime and anywhere you need it. Great tool for pilots, drag racers, engine tuners, golfers, or anyone who needs to conveniently find their Density Altitude, Altimeter Setting, Relative Aid Density (RAD), Specific Humidity or Absolute Pressure.

FlightReady E6B is a modern flight computer with the most complete set of aviation functions, conversions, and utilities for planning and flying. WHY PILOTS USE FLIGHTREADY E6B • Accurate. Conversions use exact defined factors, and airspeed and altitude calculations use the full U.S. Standard Atmosphere, maintaining accurate calculations above 36,000 feet. • Explained. Every function and conversion has built-in help that describes what it calculates, how to use it, and the formulas and conventions behind it. • Fast. Star the functions you use most to keep them at the top of the main menu, and your favorites sync to your other devices through iCloud. Open functions from Search, Shortcuts, Control Center, the Lock Screen, or the Action button. • Easy to use. Change a field's unit from the menu beside it, and every related field on the screen follows. Results automatically carry over to related functions, reducing repeated data entry. • Night-flight friendly. Dark mode uses a red-shifted amber color scheme designed for use in a dark cockpit.
