What is the normal engine start cycle limitation for the CRJ 200?

The normal engine start cycle limitation for the CRJ 200 specifies that the aircraft can perform two consecutive engine starts followed by a rest period of one minute. This limitation is critical because it helps prevent overheating and damage to the engine's starter and other components. The one-minute rest allows the internal components to cool down sufficiently before another start attempt is made, ensuring safe operational practices and maintaining the reliability of the engine system.

The rationale for allowing two consecutive starts is based on the need to facilitate quick recovery from a failed start or to respond to operational needs, while the one-minute interval is designed to strike a balance between operational efficiency and mechanical safety. If pilots adhere to this limitation, it helps ensure the longevity and performance reliability of the engine throughout its operational life.
