Which of the following could be a non-fire source of smoke or burning smell in the cabin?

• A. Cooking odors
• B. Lightning
• C. Engine fire
• D. Fuel leak

Answer: (A)

A non-fire source of a smoke or burning smell in the cabin is most commonly cooking odors from the galley. When ovens or warming equipment are in use, overheated oils, burnt food, or steam can create a burning scent that travels through the cabin even though there’s no actual fire. The other possibilities imply a real ignition risk: an engine fire or a fuel leak would involve visible smoke and require immediate fire-containment actions, and lightning, while it can affect electrical systems, isn’t a typical benign cabin odor. So, cooking odors fit the scenario of a burn-like smell without a fire. If such a smell is detected, crew would verify there’s no smoke or flames and follow the standard procedures if anything suspicious develops.
