When is continuous ignition automatically activated in the CRJ?

Continuous ignition in the CRJ is automatically activated by the Stall Warning Computer when the angle of attack threshold is reached. This function is an essential safety feature designed to help prevent engine stall situations. When the aircraft's angle of attack becomes excessive, indicating a possible stall condition, the Stall Warning Computer activates continuous ignition to ensure that the engines maintain flame stability. This action enhances the safety of the flight by helping the crew manage power and control under critical conditions.

In contrast, while ignition is involved during engine start, the automatic activation specifically due to angle of attack considerations is a more targeted safety measure. Continuous ignition is not typically required during taxi or takeoff unless specific circumstances dictate, making the Stall Warning Computer's role in activating it the primary concern in this context.
