Try to do a load check particularly with your load tending toward aft C of G so you can experience the porpoising ( phugoid ) oscillations at climb speed. The aircraft tends to be a little unstable in pitch until you can afford to increase CLIAS (above LSALT). Be aware of this characteristic coz it could cause you some concern the first time you're in that configuration (e.g. PJE ops)and didn't know it's normal.
