Requires helicopter or fixed-wing aircraft used for emergency medical service operations to have on board a terrain awareness and warning system device that meets FAA guidelines.

Requires the Administrator to issue: (1) a report on the availability, survivability, and costs of devices that record voice communications and flight data information on existing and new helicopters and fixed-wing aircraft used for emergency medical service operations; and (2) regulations to require such devices on board such aircraft.
