The Pratt & Whitney PW4000 is a family of dual-spool, axial-flow, high-bypass turbofan aircraft engines produced by Pratt & Whitney as the successor to the JT9D. It was first run in April 1984, was FAA certified in July 1986, and was introduced in June 1987.

The Pratt & Whitney PW4000 is a family of high-bypass turbofan aircraft engines with certified thrust ranging from 52,000 to 99,040 lbf (230 to 441 kN). Built as the successor to the JT9D series engines, it has found much wider application than its predecessor.

Pratt & Whitney has taken its successful PW4000 100-inch engine for the Airbus A330 to new heights with the introduction of the PW4170 Advantage70™ program. The Advantage70 is offered as a new engine and as an upgrade kit for existing engines.

Only a small number of aircraft, operated by Thai International, have PW4164 engines. The largest A330-300 fleets with PW4168 engines are operated by Korean Air, Air Berlin and Malaysia Airlines. The later PW4168A powers more aircraft, operated by Asiana Airlines, Delta, Korean Air, and USAirways.

The PW4168A powers the smaller A330-200 and later build A330-300s, while the PW4168A-1D powers the A330-300. The most recent variant is the PW4170. This is rated at 70,000lbs thrust and powers the A330-200F. The PW4170 is the newest PW4000-100 model.

Both the current PW4168A and new PW4170 engines meet regulatory noise level requirements with margin and produce the lowest total emissions—compared with other engines powering the A330. The PW4170 Advantage70 program offers both a …

Note 13: The PW4168A engine model provides the same takeoff thrust as the PW4168 engine model at or below sea level pressure altitude, and increased takeoff thrust at pressure altitudes above sea level and below 14100 feet and below temperatures of STD & 40°C. Note 14: The PW4164C engine model provides the same takeoff thrust as the ...

Pratt & Whitney has taken its successful PW4000 100-inch engine for the Airbus A330 to new heights with the introduction of the PW4170 Advantage70TM program. This program includes upgrades that enhance engine performance, save fuel, increase durability and reduce maintenance costs.

The PW4168A engine model is manufactured by Pratt & Whitney (USA) and produces 68,600 (lbs) of thrust. It entered into commercial service in 1997 on the twin-engine Airbus A330 wide-body family of aircraft comprising the A330-200 & A330-300.
