VSI stands for which term?

• A. Weather
• B. Regular Reserve
• C. Visual Service Indicator
• D. Unaccompanied Minor

Answer: (C)

Interpreting acronyms by what they describe is key here. VSI is best understood as Visual Service Indicator, a term that refers to a display or sign used to convey service status at a glance. That aligns with the idea of a visual cue that communicates whether service is available or in progress. Weather, Regular Reserve, and Unaccompanied Minor describe concepts far removed from signaling service status. Weather is about atmospheric conditions, Regular Reserve is a financial term, and Unaccompanied Minor refers to a passenger category. None of those imply a visual cue for service, so Visual Service Indicator is the term that fits the notion of a status indicator seen by people.
