Which requirement is associated with the static and altimeter check?

The requirement associated with the static and altimeter check is every 24 months. This check is critical for ensuring that the altimeter and static pressure systems function accurately and reliably, which is essential for safe navigation and altitude reporting in IFR operations. The 24-month interval is established by the Federal Aviation Administration (FAA) and reflects the importance of maintaining accurate altimeter readings for the safety of flight operations.

Regular checks help identify any inaccuracies that could lead to dangerous discrepancies in altitude readings, which can impact a pilot's ability to maintain proper flight levels, especially during approaches and departures in IFR conditions. Therefore, adhering to this 24-month requirement is crucial for aircrew and aircraft compliance and ensures operational safety.
