A major change to the Quadrajet was implemented for the 1975 model year. These newer carburetors are considered "Modified Quadrajets" or "Mod Quads". [according to whom?] In addition to the casting revisions that result in a physically larger carburetor, the primary metering rod length is different from '74 and older Q-Jets.
The de Havilland Comet, the first commercial jetliner, used four jet engines. A four-engined jet, sometimes called a quadjet, is a jet aircraft powered by four engines. The presence of four engines offers increased power and redundancy, allowing such aircraft to be used as airliners, freighters, and military aircraft.

A jet aircraft (or simply jet) is an aircraft (nearly always a fixed-wing aircraft) propelled by one or more jet engines. Whereas the engines in propeller-powered aircraft generally achieve their maximum efficiency at much lower speeds and altitudes, jet engines achieve maximum efficiency at speeds close to or even well above the speed of sound .
The type of jet engine used to explain the conversion of fuel into thrust is the ramjet.It is simpler than the turbojet which is, in turn, simpler than the turbofan.It is valid to use the ramjet example because the ramjet, turbojet and turbofan core all use the same principle to produce thrust which is to accelerate the air passing through them.
In its primary role, it serves as a regional jet, short-haul airliner, or regional airliner, while examples of the type are also in use as private jets. The BAe 146 was produced in -100, -200 and -300 models. The equivalent Avro RJ versions are designated RJ70, RJ85, and RJ100. The freight-carrying version carries the designation "QT" (Quiet ...
The first Phantoms that the USAF operated were F-4Bs loaned from the Navy, with 27 jets delivered to the 4453rd Combat Crew Training Wing at MacDill Air Force Base, Florida, in November 1963. The first operational unit was the 12th Tactical Fighter Wing , who received the USAF's first F-4Cs in January 1964, achieving initial operational ...
The Grumman F9F Panther is an early carrier-based jet fighter designed and produced by the American aircraft manufacturer Grumman.It was the first jet-powered fighter aircraft to see air-to-air combat with the United States Navy as well as being Grumman’s first jet fighter.
