Eurocopter AS350 B3 AStar

The AS350 B3 is a single-engine, light-duty helicopter employed by a number of law enforcement agencies in the United States, including the LAPD, Miami-Dade PD, Baltimore PD, U.S. Customs and Border Protection, U.S. Immigration and Customs Enforcement, and the DEA. In Europe, it is known as the AS 350 Ecureuil ("Squirrel"). It is also used as a corporate transport, seating 4-6 passengers depending upon cabin arrangement, and as an EMT helicopter, capable of carrying one or two stretcher patients plus 2 medical attendants. In a purely cargo role, the helicopter can transport one pilot and 76.28 cf of cargo, or 3,000 lbs. externally in a cargo sling.

An AS350 B3 was used to land on top of the summit of Mount Everest on May 14, 2005.

The AS350 B3 burns 37.7 gallons of jet fuel per hour at routine usage. A full load of fuel costs $429.
