A small business jet aircraft falls into which SRS category?

• A. Twin
• B. CATS
• C. CAT B
• D. CAT III

Answer: (D)

The main idea is instrument landing system capability. CAT III is the designation for an aircraft that is certified to perform precision approaches in very low visibility, often with autoland capability. A small business jet, with its high-performance avionics and capability for Category III approaches, fits this category, which is why it’s the best answer. The other terms don’t refer to this performance category—“Twin” describes engine count, not approach capability; “CATS” isn’t an official SRS category; and “CAT B” isn’t part of the CAT designation used for precision approaches.
