| British Airways Boeing 747-400 takes off from London Heathrow Airport, England |
Origin: Following its introduction in 1969, the Boeing 747 became a major success with airlines and the flying public. In the Boeing 747-400, its major influences were its family members (shown on the left). After the announcement, Northwest Airlines placed the first 10 orders of the aircraft.
Purpose: The purpose of the Boeing 747-400 was to provide an even bigger aircraft for public use with more technological advances. It is capable of holding almost 600 people based on its layout. This four-engined aircraft uses the double deck for part of its lengths and to serve as the first class lounge. Not only that but Boeing designed the aircraft so that it can be easily converted into a cargo carrier, if it is called upon.
Value: As the world's first wide-body jetliner, the 747 had revolutionized air travel, and cemented its manufacturer's dominance in the passenger aircraft market. The Boeing 747-400 is a major development and the best-selling model of the Boeing 747 family of jet airliners. For the first time there was an upper deck in an aircraft, and in the 747-400, it was bigger than any others. Also for the first time ever, the airliner offered in-cabin entertainment. The 747-400 is the most common passenger version in service, and amongst the fastest airline in service with high-subsonic cruise speeds, and even used by current Presidents as their means to travel.
Limitations: Even though at the time, companies wanted BIG aircrafts in their fleet, the demand has really died down. Most airliners simply don’t want big, four-engine planes anymore. 4 engine means more fuel, which means more money which means less efficient. The amount of passengers needing to go long distances have also decreased, meaning there are plenty of open seats available.
