FLIP planning documents are updated by what three things?

• A. NOTAMs, PCN, and UCN
• B. NOTAMs, METAR, and UCN
• C. NOTAMs, PCN, and WIND
• D. NOTAMs, AIRMET, and UCN

Answer: (A)

Understanding how FLIP planning documents stay current involves recognizing three update sources: external notices, formal publication updates, and unit-specific changes. NOTAMs deliver timely information about changes that may affect routes, airspace, navigation facilities, or procedures, so flight planning reflects current conditions. Publication Change Notices officially report updates to the FLIP publication itself between editions, describing changes to routes, procedures, and other reference data. Unit Change Notices capture local, unit-specific modifications—like temporary procedures or local frequency assignments—ensuring the plan matches how the unit operates in its area. Together these keep planning documents accurate and relevant. Weather items like METAR, WIND, or AIRMET provide current weather context for flight planning, but they don’t serve as the formal updates to FLIP publications.
