A collision alert system employs combined binaural acoustic effects combined with optical indicators to direct the attention of a person in a desired direction. The pilot utilizes normal delay and acoustic modification of high frequencies to determine roughly the direction to look for the target. A corresponding optical indicator is energized in a position corresponding to the target angle to confirm and refine the angle to the target.

[ What is claimed is:] [1.] A target indicating apparatus for alerting an occupant of an aircraft to a possible collision hazard with a target aircraft, comprising:means for determining a target angle to said target aircraft with respect to a reference line in said aircraft;means for optically indicating a direction representing the location of said target aircraft with respect to said reference line;means for acoustically guiding said occupant to look generally towards said direction; andsaid means for acoustically guiding including a binaural acoustic signal having acoustic characteristics related to said target angle, when at least one of a target aircraft range and a target aircraft elevation are such as to present the possibility of a collision.
