Visual aid for landing helicopters

摘要

A visual aid for landing helicopters includes a plurality of weighted bases and a plurality of lights designed such that they can identify a helicopter landing zone during nighttime or during the bright sunlight. The components of the visual aid are designed to provide rapid identification of the landing zone, whether the pilot of the helicopter is flying with his unaided eye or with typical night vision goggles. The weighted bases have a large surface area and are coated with a highly visible fluorescent paint. The lights are designed to emit light having wavelengths, intensities and beam patterns which will not overwhelm night vision goggles but which will be acceptably visible to pilots flying without night vision goggles. The lights and weighted bases are color-coded such that they identify both the perimeter of the landing zone and the wind direction within the landing zone.

主权项

1. A carriable portable visual aid for landing helicopters comprising a kit having:
a plurality of at least four first color bases of a first bold base color, each first color base having a first color LED light comprising a housing above the base and of a first light housing color, the first light housing color matched with said first bold base color as a first color group, the housing for supporting a first light source above the base emitting a first emitted light of a first emitted color matched with said first bold base color, each first color base having a projected surface area of at least forty square inches for daytime visibility and being of a weight for preventing displacement due to helicopter rotor wash; and a second color base of a second bold color having a second color LED light, the second light comprising a second housing above the second color base and of a second light housing color, the second light housing color matched with said second bold base color as a second color group, the second housing for supporting a second light source above the second color base emitting a second emitted light of a second emitted color matched with said second bold color, the second color base having a projected surface area of at least forty square inches for daytime visibility and being of a weight for preventing displacement due to helicopter rotor wash, the second light housing color, the second emitted color and said second bold base color of the second color group different than the first color group, whereby during daytime, dusk and nighttime said kit is employable to define a perimeter of a landing zone with the first color group and a wind direction with the second color group, wherein each of said plurality of first color LED lights is configured to emit a steady light; and said second color LED light is configured to emit a pulsing light.
