For example, with a glide ratio of 15:1, a Boeing 747-200 can glide for 150 kilometres (93 mi; 81 nmi) from a cruising altitude of 10,000 metres (33,000 ft).

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.
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).
The glide ratio of a clean A320 is 17:1 which means it can travel 17 units of distance forwards for every 1 unit of distance downward at best glide speed. Using your figure of 11,000 meters away and multiplying by 17 results in a maximum range of 187km .
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.
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.
The 747's maximum takeoff weight ranges from 735,000 pounds (333 t) for the -100 to 970,000 pounds (440 t) for the -8. Its range has increased from 5,300 nautical miles (9,800 km; 6,100 mi) on the -100 to 8,000 nautical miles (15,000 km; 9,200 mi) on the -8I.
All planes can glide without engines. Theoretically, the plane can still land perfectly. However, your survival chances really depend on the availability of a landable area within glide reach. Many jets have glide ratios of up to 15 or even more.
The process to install an interior can take up to two years. Operating a BBJ 747-8 will cost an estimated $23,000 an hour – but if you can afford to buy a your own 747, this cost is inconsequential.
Flight 236 glided for nearly 75 miles. After gliding for nearly 75 miles or 121 kilometres, the plane touched down hard in Lajes, around 1,030 feet (310 m) past the runway threshold of runway 33, at a speed of around 200 knots at 06:45 UTC.
Can planes fly on just one engine? Absolutely. That is what they are designed to do. By law, planes have to be able to fly from point A to point B, over water, on just one engine.
Aerodynamic altitude: If a commercial airliner flies too high, it will encounter less dense air passing over the wings to create lift. This can cause the plane to stall and fall out of control. Depending on the weather conditions and aircraft weight, this can occur anywhere between 40,000 and 45,000 feet.
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.
In general, it is perfectly possible for a single person to fly modern aircraft like A380. However, regulations require the presence of 2 pilots (PF and PNF).
