What is the first step in airborne navigation after confirming system setup?

Initiating engine power checks is a critical step in airborne navigation as it ensures that the aircraft is mechanically sound and ready for flight operations. Before engagement in navigation tasks, the pilot must confirm that the engine and its associated systems are functioning correctly. This verification is crucial for establishing a safe flying environment since any issues with engine power could affect the ability to navigate effectively or respond to traffic advisories from Air Traffic Control (ATC).

While reviewing navigation charts, communicating with ATC, and conducting systems checks are all important activities in the navigation process, engine power checks are fundamental to the operational readiness of the aircraft. If an aircraft cannot maintain power due to engine failures, navigation becomes secondary, as the aircraft must first be capable of sustained, controlled flight. Thus, prioritizing engine checks maintains safety and establishes a solid foundation for the following navigation and communication tasks.
