What is the minimum controllable airspeed plus how many KIAS to maintain until established on final after a controllability check?

The minimum controllable airspeed (MCA) is a critical value for pilots to understand, as it represents the slowest airspeed at which the aircraft can maintain controlled flight without stalling. In the T-6A, once a controllability check has been conducted, the recommended protocol is to add an additional margin of airspeed for safety, particularly during the transition to final approach.

The correct answer of adding 20 KIAS to the minimum controllable airspeed provides an adequate buffer to ensure the aircraft remains responsive and controllable as the pilot maneuvers for landing. This additional airspeed helps in managing potential disturbances such as wind gusts and ensures sufficient control authority for maneuvering.

Maintaining this margin assists in enhancing pilot safety and operational readiness, allowing for a more stable approach as the pilot prepares to land. Understanding the significance of maintaining this airspeed margin is essential in effective flight training and risk management.
