Patent ID: 7482951

Claim:
An auditory attitude indicator for an aircraft comprising: an audio source providing an audible signal; a stereo headset with a left side and a right side; an aircraft avionics system that provides at least aircraft pitch data and roll data to; an audio processor unit including, at least one lookup table of coefficients corresponding to a plurality of possible aircraft pitch and roll orientations, at least one first selectable multipoint impulse response filter for varying the audible signal to the stereo headset left side, the first selectable multipoint impulse response filter having a first coefficient selected by the audio processing unit from the lookup table based upon the aircraft pitch data and roll data, at least one second selectable multipoint impulse response filter for varying the audible signal to the stereo headset right side, the second selectable multipoint impulse response filter having a second coefficient selected by the audio processing unit from the lookup table based upon the aircraft pitch data and roll data; the coefficients selected to generate an audible pitch orientation signal corresponding to the aircraft pitch position and an audible roll orientation signal corresponding to the aircraft roll position; an aircraft intercom system operatively connected to the audio processor unit, the aircraft intercom system providing intermittent audio communication input through the audio processor unit and; the audible signal, the audible pitch orientation signal, the audible roll orientation signal and the intermittent audio communication input are processed by the audio processor unit to provide auditory aircraft attitude information through the stereo headset.
