Instrument Rating Checkride Practice Test

Question: 1 / 400

What is the requirement for an aircraft's altimeter under IFR?

Must be checked every 12 months

Must be inspected every 24 months

Under Instrument Flight Rules (IFR), the requirement for an aircraft's altimeter is that it must be inspected every 24 months. This regulation is crucial because the altimeter is essential for maintaining proper altitude during flight and ensuring compliance with air traffic control instructions. Altimeter discrepancies can lead to altitude deviations, which can be dangerous in busy airspace or during instrument approaches.

The 24-month inspection ensures that the altimeter system, including static port integrity and the altimeter itself, is functioning correctly and accurately reflects the aircraft's altitude. Regular checks and calibrations help prevent potential discrepancies that could lead to unsafe conditions in IFR operations.
