What instrument approach category is the T-1A when flying a straight-in approach at 114 KIAS?

The T-1A Jayhawk, when flying a straight-in approach at a speed of 114 knots indicated airspeed (KIAS), falls into Category B for instrument approach categories. Understanding approach categories is based on the aircraft's stall speed in a landing configuration, which is the speed at which it can safely operate during an approach and landing phase.

Category B is defined for aircraft with a stall speed of 61 to 120 knots in the landing configuration. Since the T-1A's approach speed of 114 KIAS lies within this range, it correctly qualifies for Category B.

Category A applies to aircraft with a stall speed of 0 to 60 knots, while Category C covers those with a stall speed from 121 to 140 knots. Category D is for higher performance aircraft with stall speeds above that, making B the correct category for the T-1A's performance at the specified speed. This classification is crucial for determining the minimum visibility and decision altitude required for instrument approaches.
