Spark Discharge


Spark discharge is an electrical discharge that occurs when an electric current passes through a gas, creating a spark. In aviation, spark discharge can occur in the engine ignition system, which is responsible for igniting the fuel-air mixture in the engine. Spark discharge is essential for the proper functioning of the engine, as it initiates the combustion process. However, spark discharge can also be a safety hazard, as it can ignite fuel vapors in the air, leading to an explosion. Therefore, aviation regulations require that all aircraft engines be equipped with ignition systems that are designed to prevent spark discharge from occurring outside of the engine.
