Research on the Improvement of Calibration Experiment Ability of Civil Aviation Special Measuring Instruments——Taking Aircraft Weighing Platform Measurement Comparison as an Example
In order to promote quality control of laboratories and improve the ability of relevant inspection institutions to test and calibrate special measuring instruments for civil aviation in laboratories,10 representative civil aviation metrology laboratories are selected to take part in the comparison based on the measurement results of the Civil Aviation Metrology and Testing Center of Beijing Aircraft Maintenance Engineering Co.,Ltd,the comparison experiment of measuring capability of aircraft weighing platforms is carried out.The experiment adopts the normalized deviation En evaluation model to evaluate the consistency of the measurement results of the reference laboratories.The results show that the En absolute values of 9 reference laboratories range from 0 to 0.87,and the differences between the measured values of each reference laboratory and the reference values are within the reasonable range.The experiment can effectively ensure the accuracy and consistency of measurement values,and has certain guidance and reference value for the future work of the testing and calibration experiment ability improvement of civil aviation special measuring instruments.
