Can a 747 glide land?

Without engine thrust, the 747 had a glide ratio of 15:1, meaning it can glide forward 15 kilometres for every kilometre it drops. After calculating the glide ratio, the crew realized that they had less than 30 minutes to regain power before they smashed into the ground.

[6] Using glide ratio of 17, the glide angle (?) is calculated using the relationship, glide ratio= cot(?). The glide angle for the Boeing 747 is approximately 3.4 degrees.

The chart notes that if a Boeing 747-400 had an operational landing weight of 475,000 lbs (215,456 kg) and wanted to land at a runway located at sea level, then the suggested runway length would be a little over 1,500 meters, or roughly 5,000 feet.

At cruising altitude, most commercial airplanes fly at a speed of roughly 500 to 600 mph. When landing, however, they must reduce their speed. A typical 747, for instance, has a landing speed of about 160 to 170 mph. And upon touching the runway, airplanes must quickly brake until they come to a complete stop.

Without engine thrust, a 747-200 has a glide ratio of roughly 15:1, meaning it can glide forward 15 kilometres for every kilometre it drops. The flight crew quickly determined that the aircraft was capable of gliding for 23 minutes and covering 91 nautical miles (169 km) from its flight level of 37,000 feet (11,000 m).

A typical takeoff speed for a Boeing 747 is around 160 knots (184 mph), depending on the jet's wing flap configuration, the number of passengers aboard, and the weight of their luggage, fuel load, current weather conditions, and other factors.

In 2013, a 77 year-old man who had never flown before landed a plane. Just last year, air traffic controllers guided a no-experience passenger safely to earth after she radioed them with a distress call. But smaller planes are way easier to fly than jets, and these are the rare success stories.

According to flight attendant Brenda Orelus, the dirties place on an airplane is not the lavatory or the tray tables. It is the seat-back pockets. IN a video that Orelus posted on TikTok she revealed to her more than 100,000 followers that the pockets are full of germs and are almost never cleaned.

It's entirely possible. While a barrel roll is technically an aerobatic maneuver, it is also a 1-G maneuver (less than 1.5 Gs are encountered during a properly executed barrel roll).

Techincally, there is only one way for the aircraft to remain hanging motionless in the air: if weight and lift cancel each other out perfectly, and at the same time thrust and drag cancel each other out too. But this is incredibly rare. To stay in the air and sustain its flight, an aircraft needs to be moving forward.

All fixed-wing aircraft have some capability to glide with no engine power; that is, they do not fall straight down like a stone, but rather continue to glide moving horizontally while descending.

Passenger jet pilots do not shut down any of the aircraft's engines without a solid reason. They may be forced to do so in the event of failure or even a relatively minor technical malfunction to avoid further damage and larger problems.

Crashes that destroy the airframe are the most obvious answer, but minor, low-speed incidents on the ground can also bring a plane's career to an end. This was the case for a Saudia Boeing 747-300, which taxied into a ditch in Kuala Lumpur in 2001.

But after five decades, customer demand for the 747 eroded as Boeing and Airbus (AIR.PA) developed more fuel efficient two-engine widebody planes. When Boeing confirmed in July 2020 that it would end 747 production, it was already only producing at a rate of half an aircraft a month.
