ABSTRACT:
Systems and methods for outputting instructions when a vehicle is not responding to a roll-angle alert. An example system includes one or more altitude sensors that determine one of altitude above ground level or barometric altitude, one or more roll-angle sensors that determine the roll-angle of the vehicle, and a processor. The processor receives the altitude and roll-angle information, determines if an excessive roll-angle condition exists based on the received altitude and roll-angle information, and generates a roll-angle alert signal if a roll-angle alert condition exists. The processor generates a roll-direction signal based upon vehicle position relative to the horizon and outputs the determined roll-direction signal via the one or more output devices, if one of the condition still exists after the time delay, the vehicle roll-angle has deteriorated away from the desired threshold, or the roll-angle rate is greater than a roll-angle rate threshold.
