Galley

What Is an Aircraft Galley?

An aircraft galley is the onboard service area where flight attendants prepare and store food, beverages, and service items. The term is borrowed from naval tradition — galleys on ships performed the same function. On commercial aircraft, galleys are built as modular, removable units called galley monuments, engineered to strict standards of weight, fire resistance, and serviceability. They are among the heaviest single furnishing items in the cabin and significantly influence weight-and-balance calculations.

Function and Layout

Galleys are positioned at the forward, aft, or mid-cabin sections of the fuselage, or in dedicated galley bays below the main deck on some wide-body aircraft. A typical galley contains:

• Ovens: Forced-air convection ovens that heat meal trays. A full-service long-haul galley may hold 3–6 full-size ovens, each capable of heating 40–60 meal units simultaneously.
• Coffee makers: High-pressure espresso machines or drip coffee systems plumbed directly to the aircraft's potable water system.
• Refrigerated compartments: Chilled storage for meals, fresh produce, and beverages, maintained at 2–5°C using galley-integrated cooling systems.
• Cart storage: Galley bays accommodate service trolleys (meal carts) in stowed positions during flight, locked by brake systems activated automatically during turbulence.
• Waste management: Dedicated trash compactors, recyclable-stream bins, and compost containers on newer aircraft (notably the Airbus A350).

Types and Variations

Galleys are classified by their position and role. Forward galley (or nose galley) serves business and first class. Aft galleys serve economy class and contain the bulk of meal carts. Mid-cabin galleys on twin-aisle aircraft serve premium economy or reduce cart-travel distances on very long aircraft. The Boeing 747 famously incorporates a lower-deck crew rest and galley below the main cabin floor, allowing flight attendants to prepare meals in a dedicated space without blocking passenger aisles.

Notable Examples

The Airbus A380 operated by Emirates features a true in-flight bar on the upper deck — a permanent counter with bar seating — located between the premium economy and business cabins. The Boeing 787-9 galley design by Boeing features an entirely modular architecture allowing airlines to reconfigure galley positions between widebody configurations with minimal structural change. The Qatar Airways Boeing 777-200LR operating the world's longest non-stop flights (up to 18+ hours) carries an exceptionally large galley volume — nearly 50% of total cabin furnishing weight — to serve three full meal services on ultra-long-haul sectors.

Related Components

The galley draws electrical power from the aircraft's main electrical bus at 115V AC for ovens and 28V DC for lighting and smaller equipment. It is connected to the potable water system and the lavatory drainage system shares the same waste management infrastructure on most aircraft. The weight of a fully provisioned galley — including meal carts, beverages, and consumables — can total 2,000–5,000 kg on a long-haul wide-body, a significant fraction of usable payload. This weight directly affects the cabin class economics of different service tiers.
