Weight and balance for a C172P

Asked by: 1278 views Flight Instructor

I am getting ready to instruct in a C172P.  Reviewing the wt and bal section, I noticed that the moment graph for the front seats stops at 400lbs.  I have always been told at Flight Safety that you can not extropolate any lines to include the moment chart.  If the front seat occupants weigh more than 400 lbs, without extropolating, how can one be legal to fly?  There is no limitation indicated in the POH.

    I’ve never heard of a loading graph line being a limiting factor in computing W&B. If you compute the weight in the front seats using the station arm, and it’s within the CG envelope, then you’re complying with CG limits. Unless there is a limitation of weight for a particular station, you’re good to go.
