A Study of Airplane Touchdown Data Measuring Devices Used during Carrier Suitability Structural Tests

摘要

The report contains the results of a statistical study of the reading accuracy of the Photo-Sonics 35mm - 4M camera. The reading accuracy limits of the Photo-Sonics camera must be increased (a decrease in accuracy) above those stated for the Cameraflex. However, this should not imply that the Photo-Sonics camera is less accurate than the Cameraflex. The opposite of this is the case. Additionally, the improvement in the reading accuracy of the Photo-Sonics camera coverage is supported by the data showing the reduction in the sink speed standard deviation from 0.34 fps for the Cameraflex to 0.27 fps for the Photo-Sonics camera.
