What is the glide ratio of a 747 400?

What is the glide ratio of a 747 400? 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.

What is the glide ratio of a Boeing 777?

With it's efficient wings the glide ratio of the B 777 should be around 15:1. Extrapolating, from a Flight Level of 390 gives us a theoretical gliding distance of about 110 Miles.

What is the glide ratio of a modern plane?

For example, if an aircraft is said to travel 2.5 nm with every 1000 ft loss in altitude, its glide ratio is equal to 15:1. This is the typical glide ratio of an airliner. Gliders have better glide ratios. There are gliders with glide ratios of 70:1.

What is the maximum glide slope for a 737?

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

Can a 747 glide without engines?

Without engine thrust, the 747 had a glide ratio of 15:1, meaning it can glide forward 15 kilometres for every kilometre it drops.

What is the best glide speed for a 747 400?

Just found on a techie forum that in a 747 in clean configuration (ie flaps and gear up) you should aim for V2+80kts as your best glide speed.

Which plane has the highest glide ratio?

The largest open-class glider, the Eta, has a span of 30.9 meters and has a glide ratio over 70:1. Compare this to the Gimli Glider, a Boeing 767 which ran out of fuel mid-flight and was found to have a glide ratio of 12:1, or to the Space Shuttle with a glide ratio of 4.5:1.

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).

What is the glide ratio of a Boeing 727?

Different aircraft have different glide ratios. A Boeing 747- 200 had a glide ratio of 15:1, and a Boeing 727 has a ratio of 17:1.

What is the glide ratio of a 737?

Assuming that a Boeing 737-300 has a glide ratio of 17:1 then if at 30,000 AGL it can glide about 96 miles under perfect conditions. The average Cessna 150 I was flying had a glide ratio of about 7:1.

Will a 747 or 777 glide if it loses engine thrust?

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.

What is the takeoff speed of a 747 in mph?

What speed does a Boeing 747 take off at? A fully loaded Boeing 747 'Jumbo Jet' on a normal long haul flight would take off at a speed of around 160 knots which is 184 mph. The calculated take-off speeds vary depending on environmental conditions, runway length and weight.
