Which among the following completes the process of Landing Gear retraction?

  1. Closing of the flaps

  2. Closing of Under Carriage door

  3. Closing of the Gear

  4. Closing of the slats
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

When landing gear is retracted in an aircraft, the wheels and struts fold up into the wheel wells. To maintain aerodynamic smoothness, the undercarriage doors (which cover these wheel wells) must close after the gear is fully retracted. This completes the retraction process. The flaps, slats, and gear itself are separate components. Option B (Closing of Under Carriage door) is correct.
