What type of maintenance is essential for the pitot-static system?

Periodic inspections are essential for the pitot-static system because this system is crucial for accurate measurement of airspeed and altitude, which are vital for safe aircraft operation. Regular inspections ensure that the components, such as the pitot tube and static ports, are free from blockages and that they maintain accurate and reliable functionality. These inspections also help identify any wear or damage that could affect performance.

Unlike regular oil changes or complete system replacements, which are not specifically applicable to the pitot-static system, periodic inspections provide the ongoing checks needed to ensure the system remains in good working condition. Calibration checks, while important, are part of the broader scope of inspections and do not address all the potential physical issues that might arise. Therefore, periodic inspections are the best practice for maintaining the integrity and functionality of the pitot-static system.
