How does storing fuel in the wings help during long-haul flights?

Most aircraft store their fuel in the wings, a method known as using integral fuel tanks. These are sections of the aircraft structure that are sealed to allow for fuel storage.

A common example is the “wet wing,” which is typically found in larger aircraft. Since these tanks are part of the aircraft’s structure, they cannot be removed for service or inspection.

Instead, inspection panels are provided for internal inspection, repair, and servicing of the tank. Large transport aircraft often use this system to store fuel in the wings, fuselage, and empennage.a321 fuel burn per hour

On some long-haul flights, fuel can make up to one-third of the aircraft’s total weight. Storing this heavy weight in the main body of the aircraft would leave insufficient room for luggage and negatively impact the aircraft’s structure. Therefore, fuel is stored in the wings.

By storing fuel in the rear of the plane could cause the front part to lift during flight due to the excess weight. As fuel is consumed, most fuel efficient commercial aircraft the front part would lean forward during landing.

To avoid this issue, fuel is stored in the wings, which reduces pressure on them during flight and evenly distributes the load across the entire airframe.

Korean Air Rolls Out Next-Generation Business Class: ‘Prestige Suites 2.0’

Korean Air has introduced its latest business class offering, the Prestige Suites 2.0, set to make its debut aboard the airline’s new Boeing 787-10 Dreamliner fleet.

This new product marks a significant upgrade from the previous Collins Apex forward-facing staggered seats, known as Prestige Suites. The Prestige Suites 2.0 is designed in a staggered 1-2-1 configuration, ensuring each passenger direct aisle access and ample privacy.

The seats offer 46 inches of pitch, 21 inches of width, and can be transformed into a flat bed measuring between 78.2 and 79.2 inches. A standout feature of these seats is the inclusion of privacy doors that stand 52 inches high, offering a more secluded experience even when positioned closer to the aisle.

Tech-savvy travelers will appreciate the suite’s cutting-edge features, which include a 23.8-inch ultra-high-definition entertainment monitor, 60W USB-C charging, AC power outlets, and wireless charging capabilities.


Moreover, Korean Air’s Boeing 787-10s will be the first in the fleet to offer Wi-Fi, enhancing connectivity for passengers. The new business class seats come with a range of amenities aimed at maximizing comfort and convenience. These include a storage cubby, a handheld remote, USB-C charging ports, and universal outlets.

The wireless charging pad is a notable highlight, reflecting the suite’s advanced technological integration. The layout of the Prestige Suites 2.0 comprises 10 rows of seats in a 1-2-1 arrangement, specifically rows 7-16 in the business class cabin. The cabin is flanked by lavatories and galleys at both the front and the rear, ensuring easy access for all passengers.

A striking departure from Korean Air’s traditional design, the new seats feature a bold brown color palette. This is a significant change from the airline’s iconic Morning Calm blue and bright white interiors.

The new design incorporates semi-matte deep brown side consoles with metallic tops, brushed coppery-almond cabinet doors, and textured tan interior shrouds, giving the cabin a modern and sophisticated look.
