Multiple Choice

A category A aircraft has a speed less than ___ knots.

Category A is defined by a speed boundary that groups slower, light aircraft together for safety and performance reasons. The limit is 91 knots, so an aircraft that stays below 91 knots is considered Category A. This boundary helps ensure that the aircraft’s low‑speed handling and stall characteristics stay within a defined, safe regime, which is important for training and regulatory considerations. The other numbers don’t fit: 100 or 101 knots would push the boundary higher, placing the aircraft in a different category, while 81 knots would impose an even stricter limit than the official threshold.
