National Transplant Flight Group has designed and implemented a unique Aviation Management Program. This program utilizes the experience of several highly experienced individuals in the on demand charter arena and is designed to enhance the safety and predictability of every National Transplant Flight Group trip. These individuals will screen the aircraft, crew and safety record of each operator contracted by National Transplant Flight Group. Risk is also balanced using a risk model which screens factors such as weather, Notams etc. This provides each flight with highest probability of success possible and is accomplished on each National Transplant Flight Group flight.
