What is the longest glide on a 747?

What is the longest glide on a 747? 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).

Can a plane glide if the engines fail?

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.

How far can an A320 Glide?

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 .

How far can a 767 Glide?

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.

How far can 787 glide?

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

Can a 747 land with full fuel?

Can a wide body airliner land with a full fuel tank? Yes! But it is safer to land an aircraft below its published MLW.

What is the maximum glide slope for a 737?

Maximum and minimum glideslope angles are 3.25 degrees and 2.5 degrees respectively.

What is the climb speed of a 747?

During normal flights, the 747-400 & 747-8 has a climb rate ranging from 2000 to 4000 feet per minute.

How far can an A380 glide?

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.

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.

How far can the A330 glide?

Piche and his first officer, Dirk DeJager, with more than 20,000 hours of flight experience between them, proceeded to glide the Airbus A330, without any power, for 19 minutes - covering some 75 miles - until landing hard at Lajes Air Base.

What plane can glide the longest?

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.

What is the glide angle of a 747?

[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.

Can 747 fly one engine?

Conclusion. While it's very clear that a 747 cannot fly properly with the failure of three engines, we can see that a single functioning engine would at least extend the aircraft's distance and prolong its time in the air. Hopefully, this would buy enough time and distance for the 747 to reach a suitable landing spot.

Can a plane stop in mid air?

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.

How high can a 747 fly?

A Boeing 747 has a cross height of 35,105 ft, while the Embraer climbs 190 to 39,370 ft. The Airbus A380 can even fly at 43,097 ft.

Has a 747 ever ditched?

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.
