Final answer:
The question addresses the importance of a static aircraft during the navigation alignment process in pre-flight, and potential indications of issues if the system's light flashes, such as no position input, bad position, or aircraft movement.
Step-by-step explanation:
The subject of the question is related to the alignment process of an aircraft's navigation system, which is a part of aerospace engineering. During the pre-flight phase, an aircraft must be steady and parked with the navigation system switched on to align itself accurately. The alignment must be done while the aircraft is static to ensure correct readings. If the light on the navigation system starts to flash, it could indicate several issues:
- No Position input: The system has not received any coordinates to begin or complete the alignment process.
- Bad Position: The coordinates inputted into the system differ by more than 1 degree from the actual position, indicating a significant error.
- Move: There has been movement of the aircraft during the alignment process, which can disrupt the accuracy of the system.
These indications are critical for the safety and accuracy of the aircraft's navigational capabilities and must be addressed immediately by the aircraft's crew or maintenance personnel.
