A moving-map display shows current route and position. A tank-switching dialog allows you to keep track of fuel level in each tank, and you will be prompted to switch tanks when the imbalance exceeds the permissible level (around 1/4 tank.) Display units are selectable - you can choose fuel in liters rather than gallons for example. Alarms are displayed and sounded when any critical parameters exceed redlines. Logged engine data can be uploaded to Savvy Analysis (a free service) to allow visualization of engine data for analysis or troubleshooting. GPS position is also logged, and groundspeed used to maintain a flight timer. Flight time and TTIS are displayed automatically at the end of a flight, or can be retrieved from the app even when away from the aircraft. A BlueMAX hardware adapter is required to use the app.
