Altimeter Test Sets

QUESTION: What is an altimeter test set used for in aviation?

ANSWER: An altimeter test set is used to calibrate and verify the accuracy of altimeters in aircraft

QUESTION: How often should altimeters be tested using an altimeter test set?

ANSWER: Altimeters should be tested using an altimeter test set at least once every two years, or whenever there is a suspected issue with their accuracy

QUESTION: What are the key components of an altimeter test set?

ANSWER: The key components of an altimeter test set typically include a pressure chamber, digital display, and various connections and adapters for different types of altimeters

QUESTION: How does an altimeter test set simulate different altitude and pressure conditions?

ANSWER: An altimeter test set uses a pressure chamber to create varying levels of pressure, simulating different altitude conditions that an aircraft may encounter during flight

QUESTION: What are the benefits of using an altimeter test set for aviation maintenance?

ANSWER: Using an altimeter test set can help ensure the safety and accuracy of altimeters, reduce the risk of in-flight discrepancies, and comply with regulatory requirements for altimeter calibration

QUESTION: What are some common procedures for conducting radio altimeter tests?

ANSWER: Radio altimeter tests typically involve connecting the tester to the aircraft's radio altimeter system, selecting various altitude settings, and comparing the readings displayed by the altimeter with the known values provided by the tester. Tests may include checks for accuracy, resolution, response time, and signal stability across different altitude ranges. Additionally, testers may perform self-tests to verify their own calibration and functionality before conducting tests on the aircraft.
