Module 11A.7–11A.8 — Equipment and furnishings (ATA 25) and fire protection (ATA 26)

Levels

• 11.7(a) Emergency equipment requirements — level 2 for A1 and B1.1.
• 11.7(b) Cabin and cargo layout — level 1.
• 11.8(a) Fire/smoke detection and extinguishing systems, system tests — level 1 A1, level 3 B1.1.
• 11.8(b) Portable fire extinguishers — level 1.

11.7(a) Emergency equipment

Emergency equipment is required by the certification specifications (CS-25) and the air operations rules (CAT.IDE.A). Typical items:

Equipment	Notes
Escape slides / slide-rafts	Required at floor-level exits where the sill is more than about 1.83 m (6 ft) above the ground; inflated by a gas bottle (CO₂/nitrogen) with aspirators drawing in ambient air; armed via girt bar; pressure gauge checks; periodic overhaul and deployment tests
Life rafts	For extended over-water flights; capacity rating and overload rating; survival kits, locator beacons
Life jackets	Under or near each seat for over-water operations; crew jackets distinguishable (often red/orange)
ELT	Automatic fixed ELT plus survival ELT in rafts on larger aircraft
First-aid kits / emergency medical kit	Number of first-aid kits depends on passenger seats; emergency medical kit on larger aircraft
Hand-held fire extinguishers	At least one in the flight deck, more in the cabin according to passenger seating, plus galley/lavatory provisions
Protective breathing equipment (PBE / smoke hoods)	For crew fighting fires; chemical oxygen generator, about 15 min supply
Portable oxygen, crash axe, torches, megaphones	Megaphones required above set passenger numbers
Emergency lighting and floor path marking	Self-contained batteries; see 11.14

Checks: correct quantity and location, seals intact, pressure gauges in the green, hydrostatic test/overhaul dates, placards and stowage.

Key fact: Emergency equipment must be serviceable or deferred under the MEL; missing or expired emergency equipment is a common airworthiness review and ramp inspection finding.

11.7(b) Cabin and cargo layout

• Seats, harnesses and belts: passenger seats on seat tracks, dynamically certified (16 g forward); crew seats with shoulder harnesses; inertia-reel locking; seat-belt and harness wear inspections.
• Cabin layout: defined by the approved LOPA (Layout of Passenger Accommodation) — seat pitch, exits, aisle widths, galley and lavatory positions.
• Equipment layout: overhead stowage bins (load placards), passenger service units (PSUs) — reading lights, gaspers, oxygen masks, call buttons, signs.
• Cabin furnishing installation: sidewalls, ceilings, partitions; materials must meet flammability standards (burn tests, heat release and smoke for large aircraft).
• Galley installation: ovens, chillers, water boilers; electrical load and circuit protection; galley carts with brakes and latches; drains.
• Cargo handling and retention: ball mats, roller trays, power drive units (PDUs), side guides and locks, ULD (unit load device) restraint, nets, floor loading limits; cargo liners (fire resistant).
• Airstairs: integral (ventral or forward door) stairs, electrically or hydraulically operated, with interlocks.
