How often must an altimeter be inspected?

Explanation:
Maintaining accurate altitude indications is essential for safe flight, especially when flying under instrument conditions. In the United States, the altimeter system must be inspected and tested for accuracy every 24 months. This check is done by a certified instrument shop and verifies that the altimeter reads correctly across standard pressure settings and at various altitudes. If the altimeter doesn’t pass, it must be repaired and re-inspected before it can be used again for IFR operations. The 60-month interval is not the standard requirement for this inspection.
