For aircraft maintenance, how often must altimeter and pitot-static system checks be performed?

The requirement for altimeter and pitot-static system checks is standardized in aviation regulations to ensure the accuracy and reliability of these critical instruments. According to the regulations, these checks must be performed every 24 calendar months. This timeline reflects the need for maintaining operational safety by ensuring that the altimeter readings and the function of the pitot-static system are accurate, which is vital for altitude measurement, airspeed indications, and overall aircraft performance.

Regular checks not only help in avoiding discrepancies that could lead to dangerous situations during flight but also align with maintenance schedules that are designed for consistent monitoring of aircraft systems over time. By adhering to this 24-month requirement, pilots and maintenance personnel can ensure that any issues are caught and rectified periodically, contributing to safer flight operations.
