The G100 comes equipped with two Honeywell TFE731-40R-200F FADEC equipped turbofan engines. Each engine is rated for 4,250 pounds of thrust at sea level. Noise levels on takeoff are 79.1 EPNdB. With these engines, the G100 needs 5,395 feet of runway to take off at sea level on a standard day. At an airport with a 5,000-foot elevation and a temperature of 25 degrees Celsius, this take-off distance increases to 8,700 feet of runway.
