helipads
Chopper touchdown zones
Helipads are designated landing surfaces for helicopters, typically marked with a large H or circle.
They appear on hospital roofs, offshore oil platforms, yacht decks, and military installations.
A helipad is smaller and simpler than a heliport, which offers fueling and other services.
The medical helicopter touched down on the rooftop helipad.
