What does the engine "start sequence" involve?

The engine start sequence primarily involves the process of initiating the engine's operation safely. This procedure is crucial as it ensures that the engine goes through the necessary checks and sequences that allow it to start without issues. Proper initiation may include actions like verifying that the fuel system is ready, confirming that power sources are correctly configured, ensuring that the appropriate starter mechanisms are engaged, and monitoring engine parameters for normal operation during the start phase.

While adjusting flight controls for takeoff, calibrating the fuel system, and performing pre-flight checks are essential components of overall flight preparation, they do not specifically relate to the engine's start sequence itself. The start sequence is a distinct phase focused solely on bringing the engines online in a controlled and safe manner, making initiatives like engine parameter monitoring and starter engagement critical components of this phase.
