What is the purpose of a meter card?

• A. To assess the performance of equipment
• B. To record the induction of a calibrated item
• C. To document maintenance schedules
• D. To track inventory levels

Answer: (B)

The purpose of a meter card is to record the induction of a calibrated item. A meter card is an essential tool used within aviation and maintenance environments to document specific details about the calibration process of equipment or instruments. It typically includes information such as the calibration date, the item being calibrated, the calibration standards used, and any relevant measurements taken during the process.

By maintaining accurate records on a meter card, personnel can ensure that all equipment remains within specified tolerances and performs reliably during operations. This is crucial for safety and operational readiness, particularly in aviation, where equipment precision directly impacts mission success and crew safety. The meter card serves as an official record that can be referenced during inspections or audits, confirming that necessary calibrations have been completed and are up-to-date.
