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.

Over 100 aviation functions, conversions, and utilities, including functions that you won't find in any other E6B. Each function uses the correct scientific formula to ensure accuracy. Other E6B apps rely on rules of thumb that can be up to 10% off. The most comprehensive, accurate, and easiest to use E6B on the App Store.

An E6B flight computer is traditionally an analog device resembling a combination slide rule and slide wheel that performs calculations specific to aviation. For example, an E6B can be used to calculate heading and groundspeed after taking into account forecast winds. An E6B is also used to calculate data used for performance planning such as density altitude. Our version goes beyond the analog E6B and even beyond all other E6B apps by including functionality to calculate time, rate and radius of turns, pivotal altitude (great for flight training use), and more.
