What crosswind component requires continuous ignition during takeoff?

The requirement for continuous ignition during takeoff in the CRJ-200 is determined by the crosswind component. Continuous ignition is needed to mitigate the risk of engine flameout, particularly during challenging weather conditions, such as when encountering significant crosswinds.

In the context of the CRJ-200 aircraft, a crosswind component of 10 knots is recognized as the threshold that necessitates continuous ignition during takeoff. By activating continuous ignition, the engine is better protected against potential disruptions in airflow, especially when the aircraft is experiencing lateral movement due to crosswinds.

The higher the crosswind component, the greater the operational challenges, warranting this precaution. Hence, while crosswinds below 10 knots typically do not require continuous ignition, reaching this threshold prompts pilots to actively initiate this safety measure to ensure a stable and safe takeoff.
