Final answer:
Altimeter Static testing is mandatory for all certificated aircraft every 24 months to ensure their safe operation and accurate altitude readings, especially for IFR operations.
Step-by-step explanation:
Altimeter Static testing is required for all certificated aircraft within the preceding 24 months. The Federal Aviation Administration (FAA) mandates this periodic testing to ensure the accuracy of the aircraft’s altimeter and static pressure system, which are critical for maintaining appropriate altitude readings and ensuring flight safety. This requirement applies specifically to aircraft that are intended for IFR (Instrument Flight Rules) operations, as accurate altitude information is essential for these flights. However, even those aircraft flying under VFR (Visual Flight Rules) conditions often undergo this test as a part of regular maintenance and safety protocols. Compliance with these regulations is essential for the certification and safe operation of the aircraft.
