Multi-engine helicopters capable of flying and hovering on a single engine, don't depict this second region. [1] As the airspeed increases without an increase in height, there comes a point where the pilot's reaction time would be insufficient to initiate a flare, and prevent a high-speed ground impact. Each increase in height increases the ...
Service began on August 1, 1976 as the second helicopter air medical program in the United States of America. The founder, Dr. James H. "Red" Duke, Jr., was the medical director for Life Flight from its inception until his death August 25, 2015. To date, Life Flight has flown more than 120,000 patient missions.
Flight for Life is a prehospital care service with many bases of operation across the United States. [1] Flight for Life is primarily known for its emergency medical helicopter transport, but also operates a fleet of land vehicles and fixed-wing aircraft for the transport of critically ill patients to specialized medical care.

The Bell 407 is a four-blade, single-engine, civil utility helicopter. A derivative of the Bell 206L-4 LongRanger, the 407 uses the four-blade, soft-in-plane design rotor with composite hub developed for the United States Army's OH-58D Kiowa Warrior instead of the two-blade, semi-rigid, teetering rotor of the 206L-4.
Translational lift is improved rotor efficiency resulting from directional flight in a helicopter.Translation is the conversion from the hover to forward flight. [1]: 2–27 As undisturbed air enters the rotor system horizontally, turbulence and vortices created by hovering flight are left behind and the flow of air becomes more horizontal.

BK 117 in 2018 In service as an air ambulance, 2008. During 1983, the initial production version, designated as the BK 117A-1 was first delivered. [5] Improved variants were quickly developed; in early 1985, the BK 117A-3, featuring an increased maximum takeoff weight and an enlarged tail rotor with twisted airfoils, was certified; two years later, the BK 117A-4, equipped with LTS 101-750B-1 ...
The Hughes OH-6 Cayuse is a single-engine light helicopter designed and produced by the American aerospace company Hughes Helicopters.Its formal name is derived from the Cayuse people, while its "Loach" nickname is derived from Light Observation Helicopter (LOH) program under which it was procured.
