Helipad

Larger helipads, intended for use by helicopters and other vertical take-off and landing (VTOL) aircraft, may be called vertiports.

Helipads are common features at hospitals where they serve to facilitate medical evacuation or air ambulance transfers of patients to trauma centers or to accept patients from remote areas without local hospitals or facilities capable of providing the level of emergency medicine required.

Rooftop helipads sometimes display a large two-digit number, representing the weight limit (in thousands of pounds) of the pad.

The world's highest helipad,[4] built by India, is located on the Siachen Glacier at a height of 21,000 feet (6400 m) above sea level.

Portable helipads can be transported by helicopter or powered-lift to place them where a VTOL needs to land, as long as there are no insurmountable obstructions nearby.
