What is the absolute ceiling of a 737-200? We're trying to find the official absolute ceiling for the 737-200 for a school project.  So far have only been able to maximum and service ceilings for this craft. Can anyone point us to the correct information for absolute ceiling?  Thanks!
Find the pertinent  performance charts for Vx (Max climb angle)and Vy (Max climb rate). You may have to extrapolate, but the altitude where Vx and Vy converge is the Absolute ceiling.
