Definition
A fire originating in the airplane's electrical system, typically caused by a short circuit, overloaded wiring, faulty component, or insulation breakdown. Indications often include the smell of burning insulation, visible smoke, sparks, or circuit breakers tripping. The standard response is to remove electrical power from the affected circuit by turning off the master switch or isolating individual systems, then managing smoke and fumes per the airplane's emergency procedures.
Plain English
A fire that starts inside the airplane's wiring or electrical equipment. The first step is to cut the electricity feeding it, usually by switching off the master switch or the specific circuit causing the problem.
Context Anchor
Encountered in emergency procedures when a pilot notices smoke, a burning smell, sparks, or abnormal electrical behavior in the cockpit or cabin.
Why Pilots Care
Electrical fires can disable flight-critical systems, fill the cabin with smoke, and spread rapidly if the power source is not isolated first.
Intuition Check
Do not assume an electrical fire means you must see open flames. In an airplane, smoke, a sharp burning smell, sparks, or hot electrical equipment may be treated as an electrical fire warning.
Example Sentence 1
When the pilot smelled burning insulation and saw smoke from behind the panel, she suspected an electrical fire and turned off the master switch.
Example Sentence 2
During preflight, the instructor pointed out how a loose wire could lead to an electrical fire if left unaddressed.
