A helipad is the landing area of a heliport, in use by helicopters, powered lift aircrafts, and vertical lift aircrafts to land on surface.
While helicopters and powered lift aircraft are able to operate on a variety of relatively flat surfaces, a fabricated helipad provides a clearly marked hard surface away from obstacles where such aircraft can land safely.
Larger helipads, intended for use by helicopters and other vertical take-off and landing (VTOL) aircraft, may be called vertiports. An example is Vertiport Chicago,[1] which opened in 2015.[2]
