avAltimeter for Android

11 things about avAltimeter

1. avAltimeter calculates a rough estimate of the increased required Take-Off distance from that at seal level from increased Density Altitude as well.

2. Unlike other aviation apps, avAltimeter uses actual barometric pressure to calculate altitude, not a GPS estimate.

3. The Bosch sensor chip built in to the iPhone 6 and later is sensitive to changes in altitude of three feet or less and has an estimated range from -1500 feet to over 20,000 feet.

4. It is the only altimeter app which has the Kollsman adjustment so you can adjust the altimeter to the current barometer setting, or to 29.92 inches of mercury for the pressure altitude.

5. avAltimeter tracks your altitude and provides a warning to use oxygen when you exceed FAA mandated limits.

6. avAltimeter calculates the temperature sensitive Density Altitude.

7. Need a quick backup for your panel? avAltimeter uses the latest Apple and Bosch technology built into the iPhone 6 and later models.

8. Set the Altimeter Setting through a popup Kollsman window or by directly setting the field altitude.

9. Based on the Density Altitude, the app also calculates True Airspeed as a function of Indicated Airspeed.

10. Earlier models of the iPhone and iPads before iPad Air 2 or Mini 4 do not have the required pressure sensing hardware and do not work.

11. Improve the take-off performance estimate by selecting your propellor type: constant speed or fixed pitch.
