When rerouted through the MLU Approach ATA, what must students do with flight plan data?

• A. Update to indicate proper routing or ATA, even if not cleared through ATA.
• B. Do not update the flight plan data.
• C. Only update if clearance to ATA is explicit.
• D. Delete previous routing.

Answer: (A)

When ATC reroutes you into a different sector or approach, your flight plan data must reflect the new routing. Entering the MLU Approach ATA means you’re now under that approach’s sequencing and clearance responsibilities, so you need the plan to show the proper routing or ATA even if you haven’t been explicitly cleared to use ATA at that moment.

Keeping the flight plan up to date ensures ATC has an accurate picture of where you’re headed, helps maintain separation, and keeps your navigation and automatic systems aligned with the actual route being flown. Not updating creates a mismatch between what the aircraft intends and what ATC expects, which can lead to confusion or conflicts. Deleting prior routing would remove situational continuity and isn’t appropriate, while waiting for an explicit ATA clearance before updating would delay essential coordination.
