What conditions would require aborting an engine start in the CRJ 200?

In the context of CRJ 200 engine start procedures, it is essential to identify specific conditions that would necessitate aborting the engine start to prevent potential damage or unsafe situations.

The conditions of a Hot START, Interrupted START, or N2 Stagnation are critical indicators that an engine start should be aborted. A Hot START occurs when the engine exceeds the maximum allowable temperature during the start phase, which can lead to serious engine damage. An Interrupted START, on the other hand, involves a situation where the engine does not complete the start sequence due to a malfunction, which could pose a risk if the engine is allowed to continue running under abnormal conditions. N2 Stagnation refers to the condition where the N2 rotor does not accelerate as expected during the start; this can indicate a problem that might cause further issues if not addressed immediately.

By recognizing and responding appropriately to these conditions, flight crews can ensure safe operations and prevent damage to the aircraft or its systems.
