After starting an aircraft engine, the initial action that should be taken is to adjust for proper RPM and check engine gauges. This action is critical for ensuring that the engine is operating within normal parameters and that there are no immediate mechanical issues that could affect flight safety.

Checking the RPM allows the pilot to verify that the engine is running efficiently and not over-revving, which could indicate a problem. Additionally, monitoring engine gauges, which typically include oil pressure, oil temperature, and other vital indicators, helps confirm that the engine is functioning properly before proceeding with further pre-flight procedures. This step is essential because early detection of anomalies can help prevent significant complications later in the pre-flight process or during flight.

While other actions such as checking fuel gauge levels, conducting a pre-flight checklist, or ensuring cabin comfort may also be important parts of the pre-flight routine or operational comfort, the immediate concern after starting the engine must focus on the engine's health and readiness for flight.
