Continuous ignition must be used during flight through which intensity of turbulence?

Continuous ignition must be used during flight through moderate or heavier levels of turbulence to ensure the safety and reliability of the flight. When flying through such turbulent conditions, there is an increased risk that engine flames could extinguish, particularly in the event of a significant change in airflow due to severe turbulence. Continuous ignition activates a system that continually provides a spark in the combustion chamber, ensuring that, regardless of the turbulence, the engine remains operational and avoids flameout.

Using continuous ignition in moderate or heavier turbulence is a precautionary measure as it enhances engine reliability, allowing the pilot to maintain control and safety of the aircraft. This practice acknowledges the varying levels of turbulence encountered during flight and aligns with standard operating procedures that aim to safeguard the aircraft against potential mechanical failure caused by environmental factors.
