FlightMath has been thoroughly tested to provide accurate calculations, and it is our goal to provide reliable, correct data for any conceivable normal flight condition. However, Federal Aviation Administration regulations hold the pilot in command as ultimately responsible for the flight. By using this software, you agree to the terms that TriVectus cannot be held liable for any accidents or damages resulting from incorrect data supplied by FlightMath. Therefore, FlightMath should not be used for flight planning. As a rule of thumb, calculations should always be verified by at least two independent techniques.
