Which information must be recorded post altimeter test?

The correct information to record following an altimeter test includes the date of inspection and the maximum altitude tested. This is essential because it provides a clear and verifiable record of the altimeter's performance under specific conditions, which is crucial for ensuring that the altimeter operates accurately and safely within the required performance parameters. The maximum altitude tested signifies the limit at which the altimeter was effective, establishing confidence in its reliability for flight operations.

Recording this information is important for compliance with regulatory standards, as well as for future reference. It allows for effective tracking of the equipment's performance over time and contributes to safety by ensuring that altimeters are functioning properly before an aircraft is cleared for flight. This type of record-keeping supports the integrity of maintenance practices and helps fulfill the responsibilities required under FAA regulations.
