How much can a 747 lift?

The 747-400F has a maximum takeoff weight of 875,000 pounds (397,000 kg) and a maximum payload of 274,100 pounds (124,000 kg). The -400F can be easily distinguished from the passenger -400 by its shorter upper-deck hump and lack of windows along the main deck.

The weight of an empty Boeing 747 Jumbo Jet without any passengers, freight or fuel is 412,300 lbs or 187,000 KGS. To put it in perspective, this is more than 4 times heavier than the empty weight of a Boeing 737-800 (which is 91,300 lb / 41,413 kg).

Early jet engines The engine intakes were small and an air hostess could barely squeeze in for a publicity photo. Boeing's first 747 jumbo had much bigger engines which produced about 45,000lbs of thrust. The most recent model, the 747-8, has engines that produce 66,000lbs of thrust.

It can dump fuel to reduce its weight. And it is a surprisingly good glider, which ensures that the chances of landing successfully with one engine running are pretty good, as it slows down the rate of descent significantly. However, one engine is not enough to maintain a safe flying altitude for a Boeing 747.

The oldest active 747 aircraft today The oldest passenger aircraft in commercial operation is Boeing 747-400 EP-MEE (SN 24383) operated by Mahan Air, a privately owned Iranian airline. IBA Insight Flights shows that this aircraft frequently makes trips between Tehran and Moscow, and last flew on 30th January 2023.

The 747-400 bolts through the sky slightly faster than its competitors, with a speed of Mach 0.85 (652.18 mph). Introduced in 1989, its primary users are British Airways, Qantas, and Lufthansa. Popular as a long-haul aircraft, the 747-400 can fly non-stop for up to 7,670 nautical miles.

Most airlines had retired their 747 fleets in favor of a new generation of long-haul aircraft, which carry fewer people than the 450-passenger giant, and, with just two engines versus the 747's four, burn less fuel.

However, the $445 million price tag of each aircraft was not sufficient to even cover the production cost, so with Airbus losing money on each A380, and with orders evaporating, it made economic sense to cease production.

An A380 crosses the landing threshold at a docile 140 knots and touches down, depending on its landing weight, at a speed as slow as 130 knots, about the same touchdown speed of some corporate jets that weigh 1/50th as much as the world's biggest airliner.

Currently, the world's biggest international airline has on order 50 A350-900s, 30 787-9s and 115 Boeing 777Xs. The airline operates 119 A380s, 123 Boeing 777-300ERs and 10 Boeing 777-200LRs. The 777X aircraft will replace the A380s, while the A350s and 787s will eventually replace the 777s.

Therefore, the ERJ135/140/145 members of the family are among the safest airliners in history. The Airbus A340 is also one of the safest, with no fatal accidents involving any of the 380 units since its introduction in March 1993.

When 150 or more passengers are loaded onto the plane, they produce more heat and humidity. Preboarding, aircraft will often use external units to pump air preconditioned to a temperature considered acceptable to passengers, usually around 70 degrees.

The tilt -- based on its inventors and a book on landing gear design -- is to reduce the touchdown drag loads (spin-up force), which in turn allows for lighter structures.
