I was watching a video and it said that switching seats on a commercial airplane would be fatal. "Switching of seats from the rear of the airplane to the front seats would result in probable accident". I think if a person weighing between 40-110kgs would be considered as of negligible weight relatively to the aircraft weight. Do such acts by passengers really affect the controls?

    $\begingroup$ Welcome to aviation.SE. One useful tip is to do a quick search before you post a question. I clicked the tag you included (weight-and-balance) and not surprisingly found that several of the first 30 questions were asking basically the same thing. $\endgroup$ – bclarkreston Dec 23 '19 at 18:25
  • $\begingroup$ By the definition of the word "negligible," negligible weights don't have any significant effect at all. When you wrote "negligible," did you mean to write "very small"? $\endgroup$ – Terran Swett Dec 25 '19 at 21:38
