Which term defines the speed limits for the Medium Speed category?

• A. Heading Track Velocity
• B. Track Speed Thresholds
• C. Medium Speed Thresholds
• D. Medium Speed Category Limits

Answer: (D)

In systems that classify speeds into categories, each category has a defined range of speeds. The phrase that names the bounds of that range for the Medium Speed category is Medium Speed Category Limits. This term directly communicates the minimum and maximum speeds allowed within that category, making it the clearest and most informational choice.

Other phrasings either point to the boundaries between categories (thresholds) or use awkward or less precise wording, so they don’t convey the complete range as cleanly. For example, thresholds imply the points where you move from one category to another, not the full set of speeds permitted inside the medium category. If you’re thinking in practical terms, the category limits would be the actual speed values that define the lower and upper ends of the Medium Speed range.
