Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to pilot glasses and an obstacle alarm device for notifying a pilot that the aircraft is approaching an obstacle, for example, while spraying pesticides.

[0002]

2. Description of the Related Art In order to improve the efficiency of agricultural work, helicopters are widely used to spray agricultural chemicals. When performing this pesticide spraying, the pilot must fly the helicopter in a low altitude area, but there are linear obstacles such as power lines in the low altitude area that are difficult to see. Accidents in which the helicopter comes into contact with obstacles such as power transmission lines account for about 15 to 20% of all helicopter accidents. Moreover,
If this contact accident occurs, it is highly likely that it will result in a fatal accident, and the mortality rate is about 70-80%. To prevent such a contact accident, conduct a ground survey or flight survey in advance. He checks the position of obstacles and flies around obstacles.

[0003]

However, when spraying pesticides, the pilot often sprays the pesticides while watching the lower fields during the flight in order to spray the pesticides accurately on the fields. For this reason, even if the position of the obstacle is confirmed in advance, there is a possibility that the user concentrates too much on spraying the pesticide and inadvertently approaches or touches the obstacle.

Therefore, an object of the present invention is to provide pilot eyeglasses and an obstacle warning device which allow a pilot to surely recognize that a helicopter is approaching an obstacle.
