In the 1801 annotation GEO/N0270/A045, what does A045 denote?

• A. New Airspeed
• B. New Level
• C. Point
• D. Time Zone

Answer: (B)

In this annotation scheme, the letters and numbers label a specific note about how the vertical profile changes along the route. The code A045 is the label for a “New Level,” meaning at this point the vertical constraint or altitude level changes to a new one. So when you see this annotation, you should expect a shift to a different altitude or flight level as defined by the chart’s vertical profile. The other options describe things that aren’t indicated by this particular annotation code, so the best match for what A045 denotes is a new level.
