In the Aircraft Flight Manual of the Bombardier CRJ700, the Minimum Flight Weight is listed as 42,000lbs. What is the meaning of Minimum Flight Weight?

    $\begingroup$ Welcome, Takeshi. Could it be that "What is the meaning of Minimum Flight Weight" is a better title to your question? $\endgroup$ – Peter Kämpf May 18 at 11:29
  • $\begingroup$ Do you simply want to know the definition of this phrase and how to ensure its complied with, or do you want to know why the limitation exists? $\endgroup$ – nexus_2006 May 19 at 14:10
  • $\begingroup$ Thank you for your comment. I'd like to know the definition and why the limitation of the weight. If flight with less than this weight, how harmful is it to operating the aircraft? $\endgroup$ – Takeshi May 20 at 1:14
  • $\begingroup$ Could it possibly be the case that if the aircraft is below the minimum flight weight, then if it encounters a strong vertical or horizontal gust that generates X pounds of additional lift, the resulting acceleration will be so strong that heavy items with lots of inertia such as batteries, engines, etc might be ripped loose from their mountings? In other words the airspeed - G-load envelope is only valid down to a certain minimum weight and the specified maneuvering speed etc does not adequately protect the plane in turbulence, or if the pilot makes rough control inputs, below that weight? $\endgroup$ – quiet flyer May 25 at 16:49
