What is the glide ratio of an Airbus A320?

The key measure of performance in gliding is the glide ratio which is related to the lift-to-drag ratio of the aircraft. 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.

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.

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.

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.

Compared with the competing single-aisle aircraft typically configured with 3-3 seating, the Boeing 737, the Airbus offers about one more inch per seat. Additionally, the A320 windows sit higher on the fuselage, which many people feel provides a more comfortable viewing.

Each had their strong points and their not-so strong-points. The A320 was more comfortable on long flights, due to the larger flight deck and lack of a control column (it has a side stick). The 737 was the best airplane I have ever flown in a crosswind.

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

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).
