Which item is not among the three that update FLIP planning documents?

• A. METAR
• B. NOTAMs
• C. PCN
• D. UCN

Answer: (A)

Understanding what updates FLIP planning documents: FLIP publications contain routes, procedures, and airfield data that may change. They are updated by notices that reflect those changes, including NOTAMs (Notices to Airmen), Plan Change Notices, and Urgent Change Notices. METARs, on the other hand, are weather observations. They provide current weather for planning and operational decisions but do not revise the FLIP planning documents themselves. So METAR is not among the items that update FLIP planning documents.
