No-flap approach and landing will cause landing distance to

• A. Increase approximately 40%.
• B. Decrease by 20%.
• C. Remains unchanged.
• D. Increase approximately 10%.

Answer: (A)

Flaps increase lift at lower speeds, letting you approach and land at a slower, more controllable speed with less energy to dissipate. When you fly no-flap, you must maintain a higher approach and touchdown speed to stay over the stall and remain controllable, which means more kinetic energy on touchdown and a longer rollout. In the Beechjet 400A, this typically results in a landing distance about 40% longer than a normal flap landing. So the no-flap configuration increases the required landing distance significantly.
