The Boeing 747-400 is a large, long-range wide-body airliner produced by Boeing Commercial Airplanes, an advanced variant of the initial Boeing 747.The "Advanced Series 300" was announced at the September 1984 Farnborough Airshow, targeting a 10% cost reduction with more efficient engines and 1,000 nautical miles [nmi] (1,900 km; 1,200 mi) of additional range.
A diagram of the aft pressure bulkhead of the Boeing 747 used on Japan Air Lines Flight 123. Multiple instances of damage to the aft pressure bulkhead have occurred; while a few cases have led to serious failures leading to aircraft losses, others have proven to be survivable.

The improved 747-400, featuring canted winglets, entered service in February 1989 with Northwest Airlines. The 747-400 is an improved model with increased range. It has wingtip extensions of 6 ft (1.8 m) and winglets of 6 ft (1.8 m), which improve the type's fuel efficiency by four percent compared to previous 747 versions. [179]
Fan air redirection is performed by devices called "blocker doors" and "cascade vanes". This is the case on many large aircraft such as the 747, C-17, KC-10, etc. If you are on an aircraft and you hear the engines increasing in power after landing, it is usually because the thrust reversers are deployed.
