When performing a static pressure system test, as required by 14 CFR 91.411, the technician must?

Answer 1

When performing a static pressure system test, the technician must follow specific steps to ensure the system is functioning correctly and provide accurate altitude readings.

Step-by-step explanation:

When performing a static pressure system test, as required by 14 CFR 91.411, the technician must follow certain steps. Here are the key steps:

1. Ensure the aircraft's static pressure system is properly installed and functioning.
2. Connect a calibrated pressure source to the static system, ensuring it matches the aircraft's static source ports.
3. Verify that the pressure indicated on the aircraft's altimeter matches the calibrated pressure source within specific tolerances.
4. If there is a discrepancy, make the necessary adjustments to bring the indicated pressure within tolerance.
5. Record the results of the test in the aircraft's maintenance records for regulatory compliance.

These steps ensure that the static pressure system of the aircraft is functioning correctly, which is important for accurate altitude readings during flight.
