What should a pilot do if they receive a "Pressure Alert" during their flight?

• A. Land immediately
• B. Ignore it, as it's usually a false alarm
• C. Follow established procedures and notify ATC
• D. Switch frequencies to an emergency channel

Answer: (C)

When a pilot receives a "Pressure Alert," it is critical to follow established procedures and notify Air Traffic Control (ATC). This alert typically indicates a potential issue with the aircraft's cabin pressure, which can be a serious safety concern. By notifying ATC, the pilot ensures that appropriate measures can be taken for their safety and the safety of others in the airspace. This communication allows ATC to assist with priorities for landing or provide necessary support.

In contrast, landing immediately could be inappropriate without assessing the situation further, as there may be time to troubleshoot the issue safely. Ignoring the alert dismisses a potentially serious condition that requires attention, and switching frequencies to an emergency channel may not be necessary if communication with ATC can handle the situation. Thus, adhering to established procedures and keeping ATC informed is the most prudent course of action in response to a pressure alert.
