Hi Jeel,
Thanks for joining and thanks for your question.
Cycling of the landing gear CREATES the most drag on an airplane.
Have a look at the question asked by Melvs. Melvs asked the same question. The 2 of you have similar interests. Maybe the 2 of you can share aviation, airport and airplane experiences.
I have a question for the both of you.
Which one of you can first tell me the name of the biggest airplane in the world?
