What is the highest glide ratio of a commercial aircraft?
What is the highest glide ratio of a commercial aircraft? Believe it or not, commercial airplanes have the ability to glide . A fully loaded 747 has a glide ratio of 15:1 meaning that it travels 15 feet horizontal for every foot of vertical drop. That means at 35,000 feet it could travel about 100 miles. The new 787 Dreamliner is around 20:1.
What is the lift to drag ratio of a 767?
Aerodynamic efficiency of the 767-200 can be judged by the maximum lift-drag ratio, estimated to be about 18.
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 747 200?
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).
What is the glide ratio of the A321?
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.
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 A380?
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.
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 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.
