ACS element text (the applicant demonstrates understanding of)

Operate the pressurization system, if equipment is installed.

Bottom line

Throughout the entire climb and cruise above 25,000 ft MSL, emphasis should be given to monitoring cabin pressurization. Careful monitoring of pressurization levels is essential during the descent to avoid the onset of hypoxia from a slow decompression. Particular emphasis should be given to cabin pressurization and procedures for equalizing cabin and ambient pressures before landing.
