What is the minimum approach speed for a stabilized approach criterion?

The minimum approach speed for a stabilized approach criterion is 130 knots. This speed is established as a threshold to ensure that the aircraft remains in a safe and controlled descent profile during the approach phase of flight. A stabilized approach is critical because it allows the pilot to maintain optimal control while ensuring that all parameters, such as descent rate, configuration, and heading, are within prescribed limits.

Setting the minimum approach speed at 130 knots aids in minimizing risks associated with low airspeed, such as stall, and helps pilots manage the aircraft's energy state effectively. Flying at this speed allows for better maneuverability and responsiveness in the event of any last-minute adjustments needed during the approach.

Higher speeds correspond with increased aerodynamic control, which is particularly important when approaching an airport environment where various factors, such as wind shear or changes in terrain, can affect performance. Therefore, adhering to the minimum approach speed criterion as part of a stabilized approach increases safety and enhances the likelihood of a successful landing.
