Wingspan  | 79.80 m
Height  | 24.10 m ]]> 2023-05-24 06:51:32 UTC https://padlet.com/yuemengs7/vc3lfrz8hq4agoz4/wish/2602870145 Shape yuemengs7 https://padlet.com/yuemengs7/vc3lfrz8hq4agoz4/wish/2602881845 - the landing gear in the wings could be as short as possible while being long enough to prevent a tail strike during rotation and allowing the spar to pass below the floor. 

- A dihedral wing increases the lateral stability in flight 

- the whole wing structure stays below the passenger deck

- the A380 has a particularly large and thick wing, so the structure needed to keep the left and right half together is a bit thicker than the space below the passenger deck

The wings incorporate wingtip fences that extend above and below the wing surface. These increase fuel efficiency and range by reducing induced drug. The wingtip fences also reduce wake turbulence, which endangers following aircraft.

With these ailerons near the wingtip, they can also flex the wing to change direction. ]]> 2023-06-04 06:15:13 UTC https://padlet.com/yuemengs7/vc3lfrz8hq4agoz4/wish/2613790054 Horizontal stabilizer yuemengs7 https://padlet.com/yuemengs7/vc3lfrz8hq4agoz4/wish/2613790384 Located on the left and right sides of the airplane’s tail, a horizontal stabilizer is designed to maintain the airplane’s trim. In works by creating an upwards force that balances the airplane, horizontally, during flight. As the airplane flies, its horizontal stabilizers will push the air upwards to prevent swings in trim. ]]> 2023-06-04 06:17:03 UTC https://padlet.com/yuemengs7/vc3lfrz8hq4agoz4/wish/2613790384 Vertical stabilizer yuemengs7 https://padlet.com/yuemengs7/vc3lfrz8hq4agoz4/wish/2613790606 A380 has very large vertical stabilizers of 48ft to create enough yaw control. The area of the vertical stabilizer needs to be larger than that on longer aircraft. ]]> 2023-06-04 06:18:12 UTC https://padlet.com/yuemengs7/vc3lfrz8hq4agoz4/wish/2613790606 Flap yuemengs7 https://padlet.com/yuemengs7/vc3lfrz8hq4agoz4/wish/2613791013 The A380 features several different flap settings, including a double-slotted flap design that provides improved lift and efficiency. Placed at the pitch to allow for better lift with the wings. It has a droop design and is called nose droop by Airbus. Located at the wings.

The secondary flight controls are retracted to reduce drag and increase the aircraft's efficiency.

The secondary flight controls, such as flaps, slats, and spoilers, are extended to increase lift and drag, allowing the aircraft to descend at a more controlled rate. The thrust reversers on the engines are also used to provide additional braking force, along with the aircraft's brakes, to slow it down after touchdown for a safer landing. ]]> 2023-06-04 06:30:02 UTC https://padlet.com/yuemengs7/vc3lfrz8hq4agoz4/wish/2613793248 Cruise yuemengs7 https://padlet.com/yuemengs7/vc3lfrz8hq4agoz4/wish/2613793362 The primary flight controls maintain the aircraft's attitude and direction, while the engines provide thrust to maintain a stable speed and altitude. The secondary flight controls, such as the spoilers/speed brakes may be adjusted to maintain the aircraft's stability and efficiency.

It measures 68.96 meters in length, a wingspan of approximately 73.3 meters and a height of about 20.78 meters. Because of its enormous size, it can carry heavy cargo which includes military equipment and heavy machinery. ]]> 2023-06-04 07:08:41 UTC https://padlet.com/yuemengs7/vc3lfrz8hq4agoz4/wish/2613802380 Shape yuemengs7 https://padlet.com/yuemengs7/vc3lfrz8hq4agoz4/wish/2613802557 The AN-124 Ruslan features a high-wing configuration, where the wings are mounted on the top side of the fuselage. The design of the aircraft allows easy loading and unloading of cargo.

Flats are swept-back, tapered, and mid-mounted on the body. There are 12 spoilers on each wing forward of the trailing edge flaps. It utilizes a system of leading-edge Krueger flaps and triple-slotted Fowler flaps to increase lift and improve low-speed performance during takeoff and landing.  ]]> 2023-06-04 07:10:53 UTC https://padlet.com/yuemengs7/vc3lfrz8hq4agoz4/wish/2613802872 Take-off yuemengs7 https://padlet.com/yuemengs7/vc3lfrz8hq4agoz4/wish/2613803222 The An-124 starts accelerating down the runway using its 4 powerful engines. As it gains speed, the wings generate lift, and the control surfaces are used to maintain stability. The elevators go up, causing more force to push down on the tail, lifting up the nose of the aircraft and changing the angle of attack on the wings, increasing lift. ]]> 2023-06-04 07:12:57 UTC https://padlet.com/yuemengs7/vc3lfrz8hq4agoz4/wish/2613803222 Size yuemengs7 https://padlet.com/yuemengs7/vc3lfrz8hq4agoz4/wish/2613804591 The size of the control surfaces, such as ailerons, elevator, and rudder, is determined based on the size of the aircraft. These surfaces need to provide sufficient authority for the pilot to control the aircraft effectively. Since the aircraft is relatively small compared to conventional ones, its flight controls are also smaller.

Lastly, the rudder is placed at the trailing edge of the vertical stabilizer to control the yaw motion. ]]> 2023-06-04 07:25:47 UTC https://padlet.com/yuemengs7/vc3lfrz8hq4agoz4/wish/2613806144 Purpose yuemengs7 https://padlet.com/yuemengs7/vc3lfrz8hq4agoz4/wish/2613806383 The primary flight controls on the Boeing 777 serve the purpose of allowing the pilot to maneuver the aircraft safely and precisely.

To reduce the landing distance required, thrust reversers are present.[9] Pilots have stated that the airlifter is relatively light on the controls and is easy to handle for an aircraft of its size.[33] A pair of TA18-200-124 auxiliary power units (APUs) are accommodated within the main landing gear fairings.[9] As a consequence of the heat and blast effects produced by these APUs, some airports require pavement protection to be deployed.[34] ]]> 2023-07-05 05:21:26 UTC https://padlet.com/yuemengs7/vc3lfrz8hq4agoz4/wish/2638525812
