<P>PROBLEM TO BE SOLVED: To provide an aircraft configured to prevent collision between the aircraft and an obstacle caused by operator misjudgment and/or a communication failure between an operator and a pilot, with a simple and inexpensive method. <P>SOLUTION: An aircraft (1) capable of hovering includes at least one sensor (10, 10', and 10") and a control unit (20). The sensor (10, 10', and 10") has a planar sweep region (R) and is configured to obtain distances (C) between first points (P) on an obstacle (O) located in the planar sweep region (R) and a second point (Q) on the aircraft (1) when the aircraft (1) is maneuvered. The control unit (20) is configured to generate a warning signal when at least one of the first points (P) lies in a safe zone (Z) including the second point (Q) on the aircraft (1). <P>COPYRIGHT: (C)2012,JPO&INPIT |
