What actions should be taken for an immediate airstart under PMU norm conditions?

In the context of performing an immediate airstart under PMU norm conditions, the correct procedure involves setting the Power Control Lever (PCL) to the IDLE position and using the Starter switch in the AUTO/RESET position.

Setting the PCL to IDLE is crucial because this allows the engine to receive fuel and air necessary for combustion, which is essential for the restart process. By ensuring that the PCL is at IDLE, the system can achieve the appropriate conditions for the engine to start again.

Using the Starter switch in AUTO/RESET mode initiates the automatic starting sequence. This mode ensures that the starter engages properly and manages the necessary parameters for a successful engine restart, such as controlling fuel flow and monitoring engine conditions during the attempted airstart.

This combination of PCL at IDLE and Starter switch in AUTO/RESET effectively prepares the aircraft for a quick and efficient engine restart following an in-flight emergency or power loss, allowing the pilot to regain control of the aircraft with minimal delay.
