What is the minimum approach speed when conducting a landing flaps landing with 1200-1500 feet of straightaway from the threshold?

• A. 110 KIAS
• B. 100 KIAS
• C. 105 KIAS
• D. 115 KIAS

Answer: (B)

The minimum approach speed, particularly during a landing with flaps extended, is crucial for ensuring that the aircraft can safely touch down and stop within the available runway length. This speed is typically calculated based on various factors, including aircraft weight, flap settings, and environmental conditions.

In this scenario, the approach speed of 100 KIAS is optimal because it aligns with safe operational practices when landing in a situation with limited straightaway available. A lower approach speed increases control and stability during the landing phase and helps to manage the landing distance effectively. It provides a buffer for any unexpected circumstances, such as wind gusts or minor distractions in the cockpit, allowing the pilot to maintain better control.

Choosing this speed helps ensure the aircraft descends appropriately, promotes fuel efficiency, and reduces the risk of stalling on final approach. It is also instrumental in providing the best performance during a landing, ensuring safety when considering the available landing surface.
