A business jet , private jet , or bizjet , or simply B.J. ,  is a jet aircraft designed for transporting small groups of people.  Business jets may be adapted for other roles, such as the evacuation of casualties or express parcel deliveries, and some are used by public bodies, government officials or the armed forces .
The Lockheed JetStar , seating ten passengers and two crew, first flew on 4 September 1957. 204 aircraft were produced from 1957 to 1978, powered by four 3,300 pounds-force (15 kN) Pratt & Whitney JT12 turbojets , then Garrett TFE731 turbofans for a 44,500 pounds (20.2 t) MTOW , then two General Electric CF700 turbofans.
The smaller, 17,760 pounds (8.06 t) MTOW North American Sabreliner first flew on 16 September 1958. Powered by two Pratt & Whitney JT12 turbojet engines then Garrett TFE731 , more than 800 were produced from 1959 to 1982.
The G550 has the efficiency to fly 6,750 nautical miles/12,501 kilometers nonstop, but also is capable of operating out of short-field, high-altitude airports. Payload is a plus, too. The G550 can transport up to 19 passengers and still has the range to fly nonstop more than 12 hours.
Powered by two Rolls-Royce engines that provide the most thrust of any jet in its class, the Gulfstream G550 has a cruise range of 6,750 nautical miles /12,501 kilometers. The G550 flies from Shanghai to Los Angeles or New York to Dubai nonstop at Mach 0.80. London to Tokyo or to Los Angeles is nonstop at Mach 0.85. Fly all those miles without the delay of fueling stops or extra landing fees.
More than 450 Gulfstream G550 aircraft are in service, and collectively, have flown more than 1 million hours, a performance that gives the G550 a National Business Aviation Association (NBAA) dispatch reliability rating of 99.9 percent―the equivalent of missing only one trip in five years of service. That’s dependability owners can count on, day in, day out, flight hour after hour.
