High altitude flight.

ACS element text (the applicant demonstrates understanding of)

High altitude flight.

Bottom line

In order to fly at higher altitudes, the aircraft must be pressurized or suitable supplemental oxygen must be provided for each occupant. Supplemental oxygen or cabin pressurization systems help pilots fly at higher altitudes and overcome the effects of oxygen deprivation.
