If ACARS is INOP during wind entry for a static/standing takeoff, what must Dispatch do?

• A. Winds must be entered in ACARS. If ACARS is INOP, Dispatch must manually enter winds into TLR data
• B. Winds must be entered in ACARS. If ACARS is INOP, Dispatch must delete winds from TLR data
• C. Winds must be entered manually by the Captain into the TLR data
• D. Winds are not required for static takeoff

Answer: (A)

Winds are essential for takeoff performance calculations. They influence V speeds, required runway length, and safe handling, so the flight team must have accurate wind data in the planning tools.

When ACARS is operating, winds should be entered there to populate the takeoff data automatically. If ACARS is INOP, the winds must be entered manually by Dispatch into the Takeoff and Landing Data (TLR) so the crew still has the correct wind inputs for their calculations. This keeps the performance data complete even without ACARS.

Deleting winds from the data would remove necessary information, and having the Captain enter winds into the TLR isn’t the standard responsibility when ACARS is down. Winds being unnecessary is false.
