The Nano flight recorder is the smallest flight recorder designed according to the highest level IGC specification. It features an integrated 66-channel GPS receiver with built-in antenna. With version 2.0 advanced power management allows up to 35 hours of stand-alone operation with built-in battery. Bluetooth is used for easy data exchange with a PDA. Five LEDs display the operational status. A 4Gb SD card is used for flight data storage. Flights are stored directly in IGC format and are downloadable through USB connection. The battery is charged when the flight recorder is connected to a computer. All new Nanos are now preloaded with 2048bit keys, which is even higher than requested by new GFAC specification.
