Abstract: A helipad includes an LED matrix built directly into the landing surface. LEDs within the matrix can be illuminated in controlled patterns to create visible objects to convey information to the pilot of an aircraft landing at the helipad and other personnel. The LEDs can be RGB color-change LEDs that are controlled to output selected colors, and can be activated with variable intensity. One of the patterns can be an arrow aligned with the wind direction as determined by an adjacent windsock, and another pattern can be determined by wind velocity as determined by an adjacent anemometer.

Abstract: A helicopter take-off and landing pad (helipad) includes a drain conduit embedded within a surface, a bed of crushed aggregate within a portion of the surface graded to be inclined toward the drain conduit, and a plurality of pavers supported by the aggregate bed and defining a substantially level top surface to serve as a landing surface for a helicopter. The plurality of pavers are permeable to liquid on the top surface to communicate the liquid to the aggregate bed. A pump connected to the drain conduit is operable to discharge liquid directed from the aggregate bed through the drain conduit to a water separator that is operable to separate water from other liquid components of the discharged liquid. At least one collection tank is fluidly connected to the water separator to receive the other liquid components discharged by the water separator.
