AutoDens does all the air density calculation at just one single touch. Temperature, air pressure and humidity have affects to the performance of engines and aircrafts. AutoDens helps to get all the required parameters automaticly via the internet and calculates the current air density, relative humidity and air pressure. It also shows your geographic position, current temperature, dewpoint, physical elevation and the barometric pressure (QNH). Features: - automatic, airport and offline (manual) mode - getting current location - loading meteo-data (METAR) from the nearest airport - calculating meteo-values for the current geo position (using up to 4 different airports nearby) - shows METAR of nearest airport in raw format - calculates density altitude, pressure altitude, relative humidity, air density and QFE - choose your preferred units (celsius / fahrenheit, hectopascal/inches of mercury, feet/meters) - database with more than 40'000 airports worldwide AutoDens might help you as a efficient tool for calculating air density. But since it relays on a working infrastructure, it might not produce accurate results in all situations (internet connection could fail or some odd weather conditions might not act as it is calculated in ISA standard-atmoshpere). Do not use this as your single source for flight preparation.

Stratus Insight is a full electronic flight bag (EFB) suite for pilots that includes AHRS with synthetic vision, TAWS, VFR sectional maps, IFR low/high charts, and geo-referenced approach plates. Please note, this app only supports airports and approach plates for US ONLY. We don't have worldwide data available at this time. More than an EFB, Stratus Insight also offers: Internet Traffic Follow along and monitor ADS-B traffic from the ground. Enable this overlay and watch as traffic is shown in real-time on the map. Radio Transcription & Playback Stratus Insight boasts a custom-built speech recognition system inside the app. When paired with a Stratus Audio Cable, the ATC Radio Transcription feature works similar to visual voicemail. ATC communications are converted into text, providing a helpful visual assist for referencing previous audio clips. This enables pilots to receive a clearance, ATIS, or other important ATC communications without needing to write them down Vertical Weather Profile The Vertical Weather Profile previews your route in the vertical slice from departure to destination, up to eight days out, so you can see the conditions you’ll encounter based on your departure time, aircraft speed, and each intermediate airport. Submit PIREPs online Running into some light chop? Submit a PIREP directly from the app to help your fellow pilots. This feature is unique only to Stratus Insight. Smart Flight Plan If a TFR or changes in weather force you to take an alternate route, the Smart Flight Plan tool considers things like fuel stops and day/night currency. Documents Store and organize all your required flight documents in one place. Uses iCloud to save and sync your documents between devices. Weight and Balance Now you can ensure you are ready for flight by performing W&B in the app for each of your aircraft. Radar Forecast Radar Forecast provides long-term weather radar simulations up to three days out, and you can fast forward your weather radar in one-hour increments. Stratus Audio Cable The Stratus Audio Cable (available to purchase for $49.99 from the Appareo web store) is needed to enable the radio transcription and playback feature. Seamless Integration with Stratus The app supports all generations of Stratus receivers, and the user experience is seamless. Stratus receivers provide WAAS GPS, AHRS, in-flight weather, and ADS-B traffic. Stratus Logbook Integration Automatically send your flights to Stratus Logbook, a free logbook app made by Appareo. Apple Watch Uses HealthKit to detect hypoxia-like symptoms for pilot health monitoring including nearby airport weather watch faces and weather radar on watch.
