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

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

Answer: (A)

In this GEO annotation, the N0270 part is signaling a change to a flight parameter, with the prefix N meaning a “New” value. The four digits that follow are the target value in knots. So N0270 is read as a new airspeed of 270 knots. The rest of the code (A045) would denote a different parameter (not the speed), but the N0270 portion specifically conveys the updated speed. The other interpretations don’t fit the format as cleanly: a speed value is what would be encoded here, not a level/altitude change, a point identifier, or a time zone. Therefore, the correct interpretation is that N0270 denotes the new airspeed.
