Post a screenshot of your cockpit set uphow do i do that ?what program do i use?thanks

You set vs at 3000fpm and it climbs at progressively higher vertical speeds until it finally stalls? Is that correct?no i set max alt 3000ft then rate of climb to 1200-1300 ft and climb to 3000ft most off the time its ok the i climb to atc req level as directed but the prob is that the aircraft for some reson suddnly starts to climb at far more then set to if its set 1200 it will go up and up till 9000 and more p.s if its better to use vnav i will dose it need to be set on the fmc to do this?
