Lavatory
The aircraft toilet — a fire-protected, smoke-detected compartment that cabin crew check, stock and secure throughout every flight.
Definition
The lavatory is the aircraft toilet compartment, built with a smoke detector, an automatic fire extinguisher in the waste bin, a door that can be opened from outside and a vacuum toilet that flushes to a holding tank. The number and location vary by type; a narrow-body carries two or three, a long-haul wide-body a dozen or more. Lavatories are locked for take-off and landing and inspected by crew at set intervals.
What it means for you
Lavatory checks are part of your cabin check cycle: paper, soap, floor, waste flap closed, smoke detector uncovered, no passenger inside too long. A lavatory smoke alarm is a genuine emergency drill you practise every year in recurrent training, and a blocked or inoperative lavatory on a full long-haul flight is one of the few things that can turn an ordinary day into a difficult one. It is also the least glamorous part of the job and appears in every honest first-year account.
In practice
On a 12-hour Qatar Airways sector the crew complete lavatory checks dozens of times between them, and the purser's log records any unit placarded inoperative for the engineers at the other end.
