The H/V curve also contains a take-off profile, indicating how a pilot can start from 0 height and 0 speed, and safely traverse to cruise. At low heights with low airspeed, such as a hover taxi, the pilot can simply cushion the landing with collective by converting rotational inertia into lift. Conversely, a complete power loss, and resultant ...
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.
As of 2023, Life Flight Network has a combined fleet of medical helicopters, fixed-wing aircraft, and ground ambulances. [12] Their current aircraft fleet includes: AgustaWestland AW119 Koala; Eurocopter EC135; Bell 429; Bell 407; Pilatus PC-12; Previous aircraft fleet includes: Cessna Citation CJ4; AgustaWestland AW109
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.

A V-n diagram showing V S (stall speed at 1G), V C (corner/maneuver speed) and V D (dive speed) A chart of velocity versus load factor (or V-n diagram) is another way of showing limits of aircraft performance. It shows how much load factor can be safely achieved at different airspeeds. [3]
Helicopter rotors are designed to operate at a specific rotational speed. The throttle controls the power of the engine, which is connected to the rotor by a transmission. The throttle setting must maintain enough engine power to keep the rotor speed within the limits where the rotor produces enough lift for flight.
WORCESTER — A Life Flight helicopter landed safely Sunday at Worcester Regional Airport after one of its engines was disabled, according to a spokeswoman at UMass Memorial Health. The chopper is ...
In response, Robinson Helicopter Company instituted stringent quality procedures and requirements, and replaced all main rotor blades on the fleet of 33 helicopters in service at the time. [ 26 ] In the early 1980s, the R22 experienced a number of student-pilot related accidents due to the R22's use as a primary flight trainer.
