What must be recorded in 4th line data for coordination purposes?

The correct approach for recording 4th line data for coordination purposes involves capturing headings, speeds, and weather deviations. This comprehensive data collection is essential for ensuring effective communication and operational safety among air traffic controllers and pilots.

Headings and speeds are vital for tracking aircraft position and movement, while documentation of weather deviations is crucial for situational awareness, especially when weather conditions can affect flight paths and safety. The inclusion of weather deviations allows for adjustments in air traffic coordination based on real-time conditions, helping to minimize potential conflicts and enhance overall safety.

The importance of this information cannot be overstated, as it contributes to the strategic management of air traffic flow and assists in maintaining separation standards between aircraft in various weather conditions. This level of detail ensures all parties involved are informed and can respond appropriately to changes in the environment or flight dynamics.
