Which of the following is NOT a limitation related to pressurization in the CRJ 200?

The correct answer is related to the limitations concerning the pressurization system in the CRJ 200. Ground handling procedures are not directly tied to the aircraft's pressurization limitations. Instead, they pertain to operational practices on the ground that ensure safety and efficiency during taxi, takeoff, and landing but do not impose limitations on how the pressurization system functions in the aircraft.

In contrast, the maximum differential pressure is a critical limit that ensures the structural integrity of the aircraft while it is pressurized. Pack overheating refers to the temperature limits of the environmental control system, which must be monitored to maintain proper functioning and safety. The APU maximum operating altitude relates to the conditions under which the Auxiliary Power Unit can effectively provide air for pressurization. Each of these factors are essential in understanding the operational limits of the CRJ 200’s pressurization system, while ground handling procedures focus on ground operations rather than pressurization.
