BFI57 - Basic Flight Instrument
The BFI57 presents an integrated display for essential flight information. It has been designed for ultralight aircraft application. It contains pressure sensors for the determination of altitude, airspeed and climb/descent rate and a built-in GPS receiver which allows the determination of ground track, present position and ground speed.
The BFI57 is not only suited as a minimum cockpit instrumentation for ULs, but also as a backup instrument in combination with classic instruments or glass cockpits. It allows the safe continuation of flight in the case of loss of power or other malfunction of the primary instruments. The built-in battery ensures independent operation of at least 3h.
Air speed as well as climb/descent rate are displayed alphanumerically and as a bar graph. The air speed indicator presents the required color markings including and configurable white range. All display options can easily be adjusted to the pilots preferences and the aircraft environment.
QNH can be set manually or automatically be derived from the GPS altitude if official information is unavailable. All display data is provided on a serial interface. Together with a megnetic compass, it represents a complete basic instrumentation.
