The Boeing 747-400 is a four-engine, long-range wide-body airliner that entered service in 1989 and became the best-selling version of the jumbo jet, with 694 delivered between 1989 and 2009. It seats 416 passengers in three classes (up to 524 in two) and flies approx. 7,285 nautical miles (13,490 km). Airlines have retired most passenger examples, but the type still works hard: 747-400 freighters carry a large share of the world’s air cargo, and a few carriers, including Lufthansa, keep flying it with passengers. The sections that follow cover its design, engines, variants, and place in aviation history.
Within the 747 family, the -400 marked the biggest single step: a new two-crew cockpit, winglets, and more range on the same iconic airframe. Its main advances at a glance:
Aircraft Engine Stands For Lease
The aircraft maintains the iconic 747 configuration while introducing revolutionary advancements. The stretched upper deck, inherited from the 747-300, combines with innovative winglets to create an aerodynamically superior aircraft. The elimination of the flight engineer position represents a significant technological leap, enabling more efficient two-pilot operations while maintaining the highest safety standards.
The exterior design showcases aerodynamic innovation through several key features:
| Feature | Specification | Benefit |
|---|---|---|
| Winglets | 6-foot (1.8-meter) | Reduced drag, improved fuel efficiency |
| Wingspan | 211 feet 5 inches (64.4 meters) | Enhanced lift and stability |
| Length | 231 feet 10 inches (70.6 meters) | Optimal passenger/cargo capacity |
The interior design prioritizes passenger comfort and operational flexibility with various seating configurations:
The aircraft boasts impressive performance metrics, with a maximum takeoff weight (MTOW) of 396,895 kg (875,000 lb). Its design incorporates significant aerodynamic improvements that enhance both fuel efficiency and overall performance.
Airlines can choose from three powerful engine options:
The General Electric CF6-80C2B1F attracted the most orders of the three, so a CF6-80C2 engine stand is the tooling most often requested for the type; PW4056 and RB211-524G/H operators each use their own dedicated stands. Each of these engines weighs more than four tonnes bare, and moving one between facilities takes planning of its own – the process is covered step by step in our aircraft engine transportation guide.
| Performance Metric | Specification |
|---|---|
| Maximum Cruising Speed | 939 km/h (507 knots) |
| Long-range Cruising Speed | 907 km/h (490 knots) |
| Range (PW-4000 engines) | 13,491 km (7,284 nautical miles) |
| Range (GE engines) | 13,444 km (7,259 nautical miles) |
| Range (Rolls-Royce engines) | 13,214 km (7,135 nautical miles) |
The Boeing 747-400 stands as a testament to versatility in commercial aviation, offering multiple variants designed for diverse operational requirements. This remarkable aircraft has established itself as a cornerstone of long-haul travel and cargo operations, demonstrating exceptional adaptability across different market segments.
The aircraft’s passenger capacity demonstrates remarkable flexibility in seating configurations:
| Cargo Area | Volume | Container Capacity |
|---|---|---|
| Forward Lower Hold | 79.3 m³ (2,800 ft³) | 16 LD-1/LD-3 containers |
| Aft Lower Hold | 69.4 m³ (2,450 ft³) | 14 LD-1/LD-3 containers |
| Bulk Cargo Space | 23.6 m³ (835 ft³) | Additional storage or 2 LD-1/LD-3 |
The 747-400 family encompasses several specialized variants:
Launched in October 1985, the Boeing 747-400 marked a revolutionary advancement in aviation technology. This ‘high-tech jumbo’ distinguished itself from earlier ‘classic jumbo’ models through significant technological innovations, including a glass cockpit, efficient tail fuel tanks, and advanced engine systems.
The aircraft’s development progressed rapidly, with key achievements including:
The 747-400 introduced several groundbreaking technologies:
The 747-400 became the most successful model in the 747 family and shaped long-haul flying for two decades. Compared with earlier 747s, it offered longer range, lower fuel burn, and a modernized cabin – a package no other four-engine airliner matched at the time.
The 747-400’s impact on aviation has been transformative, introducing several groundbreaking innovations:
The model helped airlines expand long-haul networks and pushed cockpit and efficiency standards higher across the wide-body market.
| Aircraft Type | Current Status | Key Features |
|---|---|---|
| 747-400 | Active in cargo operations | Large capacity, long range capability |
| 747-8 | Direct successor | Improved fuel efficiency, increased capacity |
| Boeing 777/787 | Modern alternatives | Enhanced efficiency, advanced passenger comfort |
While passenger variants are gradually being phased out in favor of more fuel-efficient twin-engine aircraft, the 747-400’s influence continues through its successors. The Boeing 747-8 carries forward its legacy, while modern aircraft like the 777 and 787 Dreamliner embody its spirit of innovation in long-range, high-capacity travel. The design decisions tested on the 747-400 – the two-crew glass cockpit, winglets, FADEC – remain standard equipment on airliners built today.
64.4 meters (211 ft 5 in), including the 6-foot winglets. The one exception is the 747-400D built for Japanese domestic routes, which kept the shorter 59.6-meter (195 ft 8 in) wing of the 747-300, since winglets bring little benefit on very short sectors.
416 in a typical three-class layout and up to 524 in two classes. The domestic 747-400D, flown by Japan Airlines and All Nippon Airways on trunk routes, packed in approx. 550-570 seats. Freighter and Combi versions trade part or all of that capacity for main-deck cargo.
Yes, mostly as a freighter. Cargo carriers such as Atlas Air and Kalitta Air still operate 747-400Fs and converted freighters, while only a few airlines, led by Lufthansa, continue scheduled passenger flights with the type. The last passenger 747-400 was delivered in 2005, so the fleet keeps shrinking.
One of three: the Pratt & Whitney PW4056, the General Electric CF6-80C2B1F, or the Rolls-Royce RB211-524G/H, each rated at approx. 57,000-60,600 pounds of thrust. Boeing delivered aircraft with all three engine choices within a four-month span in 1989. The CF6-80C2 became the most popular option.
The 747-8 is a 5.6-meter stretch with a redesigned wing and a single engine choice, the GEnx-2B, seating 467 passengers in three classes against the -400’s 416. It entered service in 2011 as a freighter and in 2012 in passenger form, taking over from the -400 as the top 747.
