ABSTRACT:
A device of suppressing incorrect alarms to be issued from an airplane collision avoidance system installed in a first airplane, wherein when it is found that a product obtained by multiplying a relative distance of the first airplane relative to a second airplane by a sine of a relative horizontal angle is constant or when it is found that results derived from a comparison between a relative speed of the first airplane relative to the second airplane and a speed vector in the direction toward the second airplane obtained from a relative horizontal angle of the first airplane relative to the second airplane and a speed of the first airplane in the direction of extension of a nose is substantially zero, it is determined that the second airplane is held in an immovable state, i.e., it stays in a waiting state.
