Which system component does the FDR relate to in the pushback procedure?

The Flight Data Recorder (FDR) is designed to collect and store data that is crucial for analyzing various phases of flight, including the pushback procedure. This data includes parameters such as aircraft speed, altitude, heading, and other relevant flight metrics recorded throughout the flight. By capturing this information, the FDR plays a significant role in post-flight analyses, safety assessments, and operational evaluations.

In the context of the pushback procedure, data gathered by the FDR can help evaluate the effectiveness of pushback operations and identify any anomalies or issues that may arise during this phase. Such analysis is vital for ensuring safety and improving procedures over time. The FDR's primary function of data collection for flight analysis aligns perfectly with its importance in thoroughly understanding and assessing various flight operations, including the pivotal pushback phase.
