What happens at a cabin altitude of 14000 ft according to the CPAM sequence?

At a cabin altitude of 14,000 feet, the CPAM (Cabin Pressure Acoustical Monitoring) system triggers a cabin pressure aural warning to alert the crew about the situation. This warning serves as an important indication that the pressurization status of the aircraft might be compromised, requiring the crew's immediate attention. Such an alert encourages timely actions to ensure passengers' safety by assessing the cabin's pressure status and determining the necessary operational measures to maintain safety standards.

In this scenario, the other options imply different responses or actions that are not directly related to the CPAM's response at this altitude. An immediate descent or emergency landing would usually be considered if there were further complications or a continued rise in altitude beyond safe thresholds. Altitude hold activation is not relevant to this specific situation, as it pertains to maintaining a pre-set altitude rather than responding to a pressure warning.
