What is rate of climb in aircraft? In aeronautics, the rate of climb (RoC) is an aircraft's vertical speed, that is the positive or negative rate of altitude change with respect to time.
What is the climb rate of the 737 900?
All these climb rates seem very, very slow. After takeoff & clean up, you should be aiming for 3000-4000fpm until 1000. From 10000 to 20000, as you speed up, you should be somewhere from 2500 (even 3k) to 2000fpm. Towards the cruise altitude, climb speed can be anywhere from 1500 to 500fpm.
