That means at 35,000 feet it could travel about 100 miles. The new 787 Dreamliner is around 20:1.

Answer: It would vary depending upon the wind, but around 100 miles would be a good estimate. Having all engines quit in a modern airplane is extremely rare.
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).
It is crazy to think that based on the ratio quoted, a 767 at 30,000 ft could glide approximately 113 miles. That is an impressive distance. Especially when you consider that many people without much exposure to aviation seem to often believe an airliner will nose dive if all engine power is lost.
The A380 has a glide ratio of about 15:1, which means that for every 15 kilometers (9 miles) it travels horizontally, it loses 1 kilometer (0.6 miles) of altitude. Therefore, if an A380 is cruising at 12 kilometers (7 miles) above sea level, it can glide for about 180 kilometers (110 miles) before reaching the ground.
The pilots of the Airbus A330 were able to glide the aircraft to a landing at Lajes Air Base, Terceira Island in the Azores. They were able to glide for 20 minutes and 115 miles to the airport. The reported landing speed was about 200 knots indicated airspeed, higher than the normal speed of 130 to 145.
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 .
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).
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.
As with every Boeing airplane, the 787 includes many layers of redundancy for continued safe operation, and the electrical system is no exception. For example, Boeing has demonstrated that the 787 can fly for more than 330 minutes on only one engine and one of the six generators and land safely.
This advanced fly-by-wire system also is the key to Smoother Ride Technology – unique to the 787 family -- which senses turbulence and adjusts control surfaces automatically to dampen its effects before it reaches the passengers.
The glide ratio of 17:1 means that for every 17 units the aircraft travels forward, it loses 1 unit of height. So if it's cruising at 40,000', it will travel (40000 feet x 17 feet = 680,000 feet) = 111.914 nautical miles using google convert. So that gives us a longest possible glide from 40,000 feet.
Even if some or all of an airplane's engines fail, it can still safely glide while descending in preparation of an emergency landing. An airplane won't just drop to the ground after its engines fail. Airplanes are designed with long wings to create lift, which essentially holds them in the air.
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.
However, if a pilot has initially conduct an A330 course, in order to fly the A350 would need to conduct a A330 to A350 Differences Training. Note: The A330 is a common Type Rating with the A350. Therefore, when a pilot gets qualified on either aircraft, the endorsement on his/her licence is A330/350.
The glide ratio of the A321 is calculated to be 17.3, while the eray has a glide ratio of 22.1. This improvement of aerodynamic efficiency is mainly achieved by holding major parts of the wing,s boundary layer laminar using the OA.
