The Boeing 747, often referred to as "Jumbo Jet", was a remarkable commercial jet for its time. The world's first-made car, the so-called "Queen of Heaven," boasts an upper deck and passenger capacity that has remained unmatched for decades.
747-100 entered service in 1970 now extinct, PanAm. In 1971, followed by the -200 engine with more powerful engines and higher MTOW (Max Take-Off Weight). Boeing followed this with a shortened 747SP (Special Performance), which featured a longer range, and came into service in 1976.
Boeing then launched the -300 model in 1980, which resulted from studies of an increase in capacity of 747-300 marked hull stoppers and stretched top deck. This variant together with -100, -200 and SP was collectively referred to as 747 "Classic". Now is the time for a major upgrade.
The most common version, 747-400, came into service in 1989. This variant featured along with an extended upper deck of -300, more economical engines, and was the first to represent a double glass cockpit that eliminated the flight engineer's requirement; is also the most common option in operation. -400 has a longer wingspan than the classic and was equipped with winglets that reduced resistance and is the most common aesthetic feature used to differentiate the -300 variant.
747-400 dominated the long-distance market for the coming years. It was operated by almost every major airline in the world that controlled all major international airports. Until the end of 2000, 400 players had to be confronted with competitors after the bigger Airbus A380. Boeing eventually responded by launching a new bigger, more energy-efficient variant.
The third generation of the 747-8 was launched in 2009 with Lufthansa and entered into service in 2012. This variant boasts a composite hull, as shown in Figure 787, and more economical engines. This also meant increased capacity through the extended hull and the upper deck. Unfortunately, it failed to capture the market and was unable to cope, let alone overcome, a -400 success.
The four-stroke time 747 is nearing an end, with an increasing number of airlines retiring in favor of more efficient twin-engined aircraft. The latest variant of the -8 passengers could not attract as many sales as Boeing had hoped for, having received less than 50 orders from the top 3 airlines, as the quad can no longer compete with groups such as 777, 787 and Airbus A350.
Despite this, the 747 has a great reputation as one of the most successful aircraft in history. As we see the growing number of smaller twin-engine aircraft in place, the industry will always remember the beauty and grace that Boeing 747 adorns our sky.
